ARTICLE COATED WITH LOW-E COATING WITH
ABSORBING LAYER (S)
FIELD OF THE INVENTION
Certain exemplary embodiments of this invention relate to a coated article that includes a glass substrate that supports a low-E coating, where the low-E coating includes at least one absorbent layer to control the color and / or reflectivity of the coated article. . The coated article can be used in an insulating glass (IG) unit in certain exemplary embodiments.
BACKGROUND OF THE INVENTION
Coated articles are known in the field for use in window applications such as insulating glass (IG) window units, vehicle windows, and / or the like. It is known that in certain cases, it may be desirable to heat treat (eg heat temper, heat flex and / or heat strengthen) these coated articles for quenching, flexing or the like.
Insulating glass (IG) windows are well known in the field. Conventional IG window units include at least a first glass substrate and a second glass substrate (one of which may have a solar control coating on an interior surface thereof) that are coupled to each other via at least one seal (s) or separator (s). The resulting gap or opening between the glass substrates may or may not be filled with a gas and / or evacuated at low pressure in different cases. Some IG window units are tempered. Thermal tempering of the glass substrates for these IG units typically requires heating the glass substrates to a temperature (s) of at least about 580 ° C for a period of time sufficient to enable thermal tempering. Architectural, monolithic windows for use in homes or buildings are also known in the field and may include a coating supported by a glass substrate. Fixed home windows can be made of glass sheets. Optionally, these monolithic windows can also be thermally tempered for safety. Heat treatment (eg, thermal tempering) of coated articles typically requires the use of temperature (s) of at least 580 ° C, more preferably of at least about 600 ° C, and even more preferably of at least 620 ° C.
In certain situations, designers of coated articles frequently strive for a combination of desirable visible transmission, desirable color, low reflectance, low emissivity (or emission coefficient), and low sheet resistance (R<sub>s</sub>). The low emissivity (low-E) and low sheet resistance characteristics allow these coated articles to block significant amounts of IR radiation in order to reduce for example undesirable heating of the interior of the vehicle or building. Designers of coated articles also seek to have particular color appearances (eg, when viewed from outside a building or vehicle in which the coated article is mounted) and / or low visible reflectance. Typically, thick reflective layers of IR radiation (eg, silver-based layers), while blocking IR radiation, cause the visible reflectance to increase. Thus, in the past it has been difficult to achieve a combination of good IR radiation blocking and at the same time low or relatively low visible reflectance.
In view of what. above, it will be apparent to those skilled in the field that there is a need in the field for a coated article having one or more of a desirable visible transmission, desirable color, low reflectance, low emissivity (or emission coefficient), and / or low laminar resistance (R<sub>s</sub>). In certain exemplary embodiments, it will be apparent that there is a need in the field for a coated article (eg, for use in an IG window unit) that can achieve a desirable color combination (eg, a * and / ob * desirable), fairly low visible reflectance, low emissivity and / or sheet resistance, and desired visible transmission.
BRIEF SUMMARY OF THE INVENTION
A coated article including a low-E coating supported by a substrate (eg, a glass substrate) is provided in certain exemplary embodiments of this invention. In certain exemplary embodiments, the coated article has one or more than one desirable visible transmission, desirable color, low reflectance, low emissivity (or emission coefficient), and / or low sheet resistance (R<sub>s</sub>). In certain exemplary embodiments, the coated article (eg, for use in an IG window unit) may achieve a desirable color combination (eg, desired * and / or b * reflective values), fairly low visible reflectance, Low emissivity and / or laminar resistance and desired visible transmission. As used herein, a coated article may or may include a coated article, monolithic and / or a unit of
IG.
In certain exemplary embodiments of this invention, an absorbent layer for adjusting the color and / or reflectivity of the low-E coating is included for the purpose of allowing coloration and / or reflectivity of the coating (and coated article) to be selectively controlled. The coated article may have a bronze, green, neutral, blue or other color tint in different exemplary modalities. The visible reflectance on the glass (or outer) side of the coated article can be advantageously reduced. In certain exemplary embodiments, the absorbent / breaker layer is included to form a coated article with color and / or reflectivity properties that are more easily controllable / adjustable, and which may have reduced glass side reflectance (Y<sub>g</sub> and / or Rfuera) · Advantageously, it has been discovered that the inclusion of the absorbent layer to adjust the color and / or reflectivity between dielectric layers, together with the manipulation of the thickness of the other layer (s) present (s) in the low-E coating, reduces the reflectance of the glass side and produces desirable, adjustable tints such as bronze, green, neutral and blue, while at the same time allowing it to be used, if desired, a relatively thick reflective layer of IR radiation. In other words, it has been discovered that the inclusion of an absorbent layer to adjust the color and / or reflectivity provides articles coated with adjustable tint of bronze, green, neutral and / or blue color which indicates that the desired color can be achieved and / or allows a combination of acceptably low visible reflectance and low emissivity and / or sheet resistance.
The color of the glass (or exterior) side (for example, values a *<sub>g</sub> and / ob *<sub>g</sub>) can be optimized based on the thickness and materials / composition of the individual layers in the low-E coating in certain exemplary modalities, which is advantageous from aesthetic and architectural perspectives. Additionally, good solar properties (eg, low laminar strength and acceptable visible transmission) are also possible in certain exemplary embodiments of the coatings disclosed herein. I know

DETAILED DESCRIPTION OF THE INVENTION
Articles coated in accordance with exemplary embodiments of this invention can be used in applications such as IG window units, vehicle windows, monolithic architectural windows, residential windows and / or any other suitable application including single or multiple glass substrates. Similar reference numbers in the various figures refer to similar parts / layers in this document.
Laminar resistance (R<sub>s</sub>) is indicative of the emissivity or emission coefficient. Low sheet resistance is achieved in certain exemplary embodiments of this invention, in combination with desired values of color and reflectance, due to the presence of the absorbent layer (s). In certain exemplary embodiments of this invention, a coated article develops a laminar strength (R<sub>s</sub>) not greater than approximately 10.0 ohms / square, more preferably not greater than approximately 9.0 ohms / square, even more preferably not greater than approximately 5.0 ohms / square, even more preferably not greater than approximately 4.0 ohms / square and possibly or much more preferably less than or equal to about 3.5 ohms / square. These laminar strength values, applicable to any embodiment of this invention, may be before and / or after optional heat treatment such as thermal tempering of the coated article. In certain exemplary embodiments, a laminar resistance of not greater than 3.0 ohms / square may be possible. Low laminar resistance values are indicative of low emissivity.
In certain exemplary embodiments of this invention, a low-E coating comprises an individual IR radiation reflective layer comprising silver and / or gold, although this invention is not limited in this way in all cases. While other numbers of reflective layers of IR radiation may sometimes be provided, the use of one is preferable in certain cases where a low mission coefficient can be achieved and no more of these layers are required which does so. coatings are easier and more cost-effective for manufacturing and less susceptible to performance problems.
In certain exemplary embodiments of this invention (eg, see Figures 1-5), the coated articles may or may not be heat treated (eg, heat tempered). In certain exemplary embodiments (eg, see Figures 15), the coated articles may have an emissivity (normal and / or hemispherical) not greater than about 0.12, 0.11 and / or 0.10, more preferably not greater than about 0.06, even more preferably not greater than about 0.05 and much more preferably not greater than about 0.04 (eg 0.037). In certain exemplary modalities, after heat treatment and measured in monolithic form, coated articles (eg, see Figures 1-5) before and / or after HT are capable of developing visible transmission (111 ° C, degrees ) of up to about 60%, more preferably up to about 50% and much more preferably not higher than 45% or 40%. In certain exemplary embodiments, the coated article has a visible transmission of about 20-50%, more preferably about 30-48%, in monolithic and / or IG unit form.
The solar factor (SF or g-value), calculated according to the EN 410 standard, refers to a relationship between the total energy entering a room or the like through a glazing with respect to the incident solar energy. Thus, it will be appreciated that the lower SF values are indicative of good sun protection against undesirable heating of rooms or the like protected by windows / glazing. For example, a low SF value is indicative of a coated article (for example, an IG unit such as double or triple glazing) that is capable of keeping a room quite cool in summer months during hot environmental conditions.
While low SF values are typically desirable for coated articles such as IG window units, achieving lower SF values typically originates at the cost of visible transmission and / or staining. It is often desirable, but difficult, to achieve a combination of acceptable visible transmission, desirable glass side coloration, and a low SF value for a coated article such as an IG window unit or the like. In this respect, the relationship between visible transmission (T<sub>vis</sub>) with respect to SF is sometimes referred to as selectivity. In other words, the selectivity of a coated article is defined by T<sub>vis</sub>/ SF. High selectivity values are frequently desirable, as this combines a desirable or high visible transmission with a low SF value which is indicative of good IR radiation blocking.
In certain exemplary embodiments of this invention, a coated article is provided with a stack of layers which can allow the coated article to achieve one or more of a good selectivity (T<sub>v</sub>i<sub>s</sub>/ SF), an acceptable solar factor (SF) and / or low emissivity. One, two, three, or all of these features can be achieved in different embodiments of this invention (eg, see Figures 1-5). When good selectivity is achieved (T<sub>vis</sub>/ SF), a higher visible transmission ratio is provided (T<sub>V</sub>i<sub>S</sub>) with respect to the solar factor (SF), which will be appreciated by those experts in the field.
In certain exemplary embodiments of this invention (eg, see Figures 1-5), a coated article such as an IG window unit develops a selectivity value (T<sub>vis</sub>/ SF) of at least about 1.12 or 1.20, more preferably at least about 1.30, even more preferably at least about 1.35 and in certain cases at least about 1.40 or 1.43. In certain exemplary embodiments of this invention, good selectivity is achieved without sacrificing SF values. In other words, good selectivity values are achieved in combination with fairly low SF values. In certain exemplary embodiments of this invention, the coated articles develop a good selectivity value, in combination with an SF not greater than 31 and more preferably an SF not greater than approximately 30, even more preferably an SF not greater than approximately 29 and still more preferably an SF not greater than about 28. This allows IG coated articles and / or window units, for example, to develop desirable visible transmission while at the same time blocking the possibility of significant undesirable radiation (eg IR) reaching the interior of a building or Similary.
In certain exemplary embodiments of this invention, coated articles having a single IR radiation reflective layer are capable of reduced glass side reflectance. In certain exemplary embodiments, before and / or after HT, coated articles such as IG window units according to certain exemplary embodiments of this invention have a glass side (Y) reflectance of not more than about 16%, more preferably about 15% or less, even more preferably about 14% or less, while maintaining a desirable color.
The terms heat treatment and heat treatment used herein mean to heat the article to a temperature sufficient to achieve thermal tempering, heat bending and / or heat strengthening of the glass inclusive article.
This definition includes, for example, heating a coated article in an oven or incinerator to a temperature of at least about 580 ° C, more preferably at least about 600 ° C, for a period of time sufficient to allow tempering , flexion and / or strengthening with heat. In certain cases, the HT can be for at least about 4 to 5 minutes. The coated article and / or IG unit may or may not be heat treated in different embodiments of this invention.
Figure 1 is a side, cross-sectional view of a coated article according to an exemplary, non-limiting embodiment of this invention. The coated article includes substrate 1 (eg, a clear, green, bronze-colored, or greenish-blue colored glass substrate approximately 1.0 to 10.0 mm thick and a low-E coating (or layer system) 30 provided on substrate 1 either directly or indirectly. The coating (or layer system) 30 includes, for example: a bottom dielectric layer 3 which may be silicon nitride (eg Si<sub>x</sub>N<sub>and</sub> I do<sub>3</sub>N<sub>4</sub>), silicon oxide and / or silicon oxynitride in different embodiments of this invention, an absorber / breaker layer for adjusting the color and / or metallic or substantially metallic reflectivity 4 (eg, of or including one or more Ni, Cr, NiCr, Nb, Zr, NbZr, Si, Ti, Zn, Sn, Cu, Al, V, Mn, Mo, Pd, Ta, W, In,
InSn and / or stainless steel and / or a mixture (alloy) thereof; the above materials may be partially and / or fully oxidized and / or nitrided), a dielectric layer 5 which may be of or may include silicon nitride (eg Si<sub>x</sub>N<sub>and</sub> I do<sub>3</sub>N<sub>4</sub>), silicon oxide and / or silicon oxynitride in different embodiments of this invention (and which may be of a material and / or composition substantially similar to or equal to layer 3 in certain embodiments), a lower contact layer 6 ( which contacts the reflective background IR radiation layer 7), a conductive and preferably metallic or substantially metallic infrared (IR) reflective layer 7, an upper contact layer 8, a dielectric layer 9, an absorbent layer for adjusting color and / or ref ectivity 10 (eg, of or including one or more of Ni, Cr, NiCr, Nb, Zr, NbZr, Si, Ti, Zn, Sn, Cu, Al, V , Mn, Mo, Pd, Ta, W, In, InSn and / or stainless steel and / or a mixture (alloy) thereof; the above materials may be partially and / or completely oxidized and / or nitrided), one coat dielectric 11 and an outer coating layer 12. Similar layers 3 and 5, layers 9 and 11 may be of the same material and / or composition in certain exemplary embodiments, so that the dielectric layers are divided by the intervening absorbent layer. It is noted that all of the above layers may or may not be included in the low-E coating 30 in certain exemplary embodiments. In particular, only one of the absorbent layers for adjusting color and / or reflectivity 4, 10 may be present in some embodiments (eg, see Figures 3 (a) and 3 (b)), or both may be present (eg For example, see Figure 1, Figure 4 (c) and Figure 5 (c)). Contact layers 6 and 8 each contact IR radiation reflective layer 7 (eg, an Ag-based layer). The aforementioned layers 3-12 constitute the low-E (ie, low emissivity) coating 30 that is provided on the glass or plastic substrate 1. Additional layers may also be provided.
In monolithic cases, the coated article includes only a glass substrate 1 as illustrated in Figure 1. However, the coated, monolithic articles in this document can be used in devices such as laminated vehicle windshields, IG window units and the like.
Figure 2 is a cross-sectional view of an IG window unit, showing that the coating 30 can be provided on the inner side of the glass substrate 1. However, the invention is not limited in this way and it is observed that the Coating 30 can be provided on any glass substrate, preferably on the side of the substrate closest to opening 17.
As Figure 2 depicts, an IG window unit can include two separate glass substrates 1 and 50. An exemplary IG window unit is illustrated and described, for example, in US Patent Document No. 2004/0005467, the description of which is hereby incorporated into this document by way of reference. A window unit
Exemplary IG may include, for example, the coated glass substrate 40 shown in Figure 1 (or any of Figures 3-5) coupled to another glass substrate 50 by way of spacer (s), sealer (s) or the like (15), with an opening 17 that is defined therebetween.
This opening 17 between the substrates in the IG unit modalities can in some cases be filled with a gas such as argon (Ar). An exemplary GI unit may comprise a pair of separate clear glass substrates each approximately 3-4 mm thick, one of which is coated with a low-E 30 coating of this document in certain exemplary cases, where the opening between substrates can be approximately
5 at 30mm, more preferably from about 10 to 20mm and much more preferably from about 16mm. In certain embodiments, the coating 30 is provided on the interior of the glass substrate farthest from the center (eg, closest to the outside) 1 as shown in Figure 2. However, in other embodiments, the coating 30 can be provide on the interior surface of any substrate that faces the opening. A GI unit may also include additional substrate (s), such as three glass substrates, in certain exemplary cases.
Figures 3-5 show other exemplary embodiments of this invention, the coatings of which can be used in conjunction with Figures 1 and / or
2.
It has been advantageously found that the inclusion of an absorbent layer to adjust the color and / or ref ectivity (4 and / or 10) of varying thicknesses in the above-mentioned layer stack (eg see Figures 1-5) in one or more locations can result in desirable optical qualities. More specifically, in certain exemplary embodiments, by adjusting the thickness of the absorbent layer (s) to adjust the color and / or reflectivity 4 and / or 10, the staining of the glass side of the coated article ( values a *<sub>g</sub> and b *<sub>g</sub> on the glass side) can be adjusted to appear a certain color when the window unit is viewed from the outside. The absorbing or breaking layer (s) 4 and / or may be conductive in certain exemplary cases. Unless stated otherwise, values a *<sub>g</sub> and b *<sub>g</sub> Refers in this document to reflective coloration on the glass side, as seen from the glass side of a coated, monolithic item or from the side of a GI window unit adapted to face the exterior of the building or structure . Similarly, visible glass-side reflectance (Y) refers to visible glass-side reflection, as seen from the glass side of a coated, monolithic article or from the side of an IG window unit adapted to be oriented towards the exterior of the building or structure.
More particularly, in certain exemplary embodiments, the inclusion of the absorbent layer 4 between two dielectric layers 3 and 5 can result in a coated article having desirable optical qualities. In certain exemplary embodiments, the dielectric layers 3 comprise substantially similar equal materials / composition.
Indeed, in certain exemplary embodiments, a silicon-based layer is divided into two layers, 3 and 5, and an absorbent layer for adjusting color and / or reflectivity is provided between the two dielectric layers. Layers 3 and 5 can be of different thicknesses in certain exemplary embodiments. In other embodiments, layers 3 and 5 can be substantially the same thickness. The thicknesses of layers 3 and 5 can be altered to contribute to achieving desirable glass-side color (for example, desirable values a *<sub>g</sub> and b *<sub>g</sub>). The desirable color of the glass side may be different in certain cases.
In certain exemplary embodiments, the glass side color of the coated article (a * and b * for the glass side) may be bronze, green, neutral, or blue. In this way, a coating 30 can be applied on a clear glass substrate 1 and the coated article (monolithically, or when measured as a unit of GI) will appear to be colored while still having desirable characteristics such as those of a traditional low-E coating, such as a laminar resistor (r<sub>3</sub>) not greater than about 10.0 ohms / square, 9.5 ohms / square, or 9.0 ohms / square, more preferably not greater than about 5.0 ohms / square, even more preferably not greater than about 4.0 ohms / square, and much more preferably less than or equal at approximately 3.5 ohms / square before and / or after optional heat treatment such as tempering, an emissivity less than approximately 0.12, 0.11 and / or 0.11, more preferably less than about 0.06, even more preferably less than about 0.05 and much more preferably less than about 0.04 (eg 0.032). The resulting coated article may have a reduced glass side (or building exterior) reflectance (Y) of 16% or less, more preferably about 14% or less (eg, one IG unit) in certain embodiments. exemplary, depending in part on the desired color.
In certain exemplary embodiments, depending in part on the material selected for the absorbent layer (s) 4 and / or 10, and the thicknesses and materials of layers 3-12, a coating made in accordance with certain embodiments Exemplary can be provided on a clear glass substrate, providing the glass substrate with a desired color appearance (eg, bronze color). For example, a 3 0 coating can produce a coated article that, when viewed from the glass side (or the exterior of the building in Figure
2), in certain exemplary modalities, it has a tint that is bronze, neutral, green, deep navy blue and / or other colors made from combinations thereof.
The absorbent layer (s) is (are) advantageous because the glass and / or exterior side reflectance is decreased and desirable visible transmission, color and low SF can be achieved, without sacrificing laminar resistance. For example, and without limitation, it is often more aesthetically pleasing when a structure such as a building has windows with a lower glass side reflectance. Architects may thus prefer that the visible reflectance on the glass (or exterior) side be lower, but may not wish to sacrifice the visible laminar, color and / or transmission resistance for this purpose. In certain exemplary embodiments, the thickness of the IR radiation reflective layer (s), which may comprise silver or gold, can be increased. Increasing the thickness of layer 7 can increase the reflectance of the glass side; thus, if the glass-side reflectance is decreased by the inclusion of the absorbing layer (s) 4 and / or 10, but is increased by thickening layer 7, the net change in the reflectance on the glass side can be minimal or even zero or substantially zero. Increasing the thickness of the IR radiation reflective layer 7 is desirable because it increases the ability of the IG unit to block / reflect IR radiation, which would reduce the amount of IR radiation entering a building, structure, vehicle, etc., through the window.
In certain exemplary embodiments, layers 3-12 are cathodically deposited on a glass substrate.
This may be applicable for any of Figures 15. The target (s) for cathodic deposition may be target (s) for cathodic rotary or cylindrical magnetron deposition (which are not shown) in exemplary embodiments of this invention. Metal and / or ceramic lenses can be used.

The absorbent layer 4 can be of or can include any of the following materials, or a mixture (alloy) of any of the materials: Ni, Cr, NiCr, Nb, Zr, NbZr, Si, Ti, Zn, Sn, Cu, Al, V, Mn, Mo, Pd, Ta, W, In, InSn and / or stainless steel. Optionally, the materials can be partially or completely oxidized and / or nitrided. Preferably, the absorbent layer 4 can comprise or consist essentially of Ni, Cr, NiCr, Nb, Zr, NbZr and / or oxides and / or nitrides thereof. Layer 4 may be from about 10 to 150A thick in certain exemplary embodiments, more preferably from about 20-70A thick. However, in other embodiments, layer 4 may be thicker, sometimes significantly, than 150A.
Still referring to Figures 1-5, contact layers 6 and 8 may comprise Ni, Cr, and / or NiCr, or oxides thereof, in certain exemplary embodiments. Also, or instead, other suitable materials can be used. Contact layers 6 and 8 can be partially or completely oxidized and / or partially or completely nitrided in certain exemplary cases. In certain exemplary embodiments, layers 6 and 8 can help protect the reflective layer from IR radiation 7 from oxidizing during deposition of other layers and / or during heat treatment. Instead, other materials can be used in alternative ways. Contact layers 6 and 8 can each be from about 10 to 150A thick in certain exemplary embodiments, more preferably from about 10-60A thick.
Continuing reference to Figures 1-5, the dielectric layers 9 and 11 may comprise or consist essentially of silicon nitride, and in other exemplary embodiments, they may comprise or consist essentially of silicon oxide and / or silicon oxynitride. Layers 9 and 11 can be fully or partially oxidized and / or nitrided. In certain exemplary embodiments, the dielectric layers 9 and 11 may comprise the same or substantially similar materials and / or composition. It is noted that all layers of silicon nitride, silicon oxynitride and / or silicon oxide in this document (eg see 3, 5, 9 and / or 11) can be optionally doped with aluminum (eg 1- 5%), stainless steel or the like. In certain modalities, the thickness or
of the dielectric layers 9 and 11 can be the same or substantially similar. Layers 9 and 11 can each be from about 70 to 12 00 Á in certain exemplary embodiments. In certain exemplary embodiments, only one of layers 9 and 11 may be present; however, in other embodiments, both layers can be provided.
Layer 10 may be an absorbent layer for adjusting color and / or reflectivity in certain exemplary embodiments (eg, see Figures 1-5). With respect to the absorbent layers 4, 10, a stack of layers can comprise layers 4 and 10, layer 4 only, or layer 10 only. Layer 10 can be of or can include any of the following materials, or a mixture (alloy) of any of these materials: Ni,
Cr, NiCr, Nb, Zr, NbZr, Si, Ti, Zn, Sn, Cu, Al, V, Mn, Mo,
Pd, Ta, W, In, InSn and / or stainless steel. The materials can be partially or completely oxidized and / or nitrided. Preferably layer 10 can comprise or consist essentially of Ni, Cr, NiCr, Nb, Zr, NbZr and / or oxides and / or nitrides thereof. The absorbent layer 10 may be approximately 10 to 150A thick in certain exemplary embodiments. However, in other embodiments, the absorbent layer 10 may be thicker than 150A. Layer 10 may not be included in certain embodiments, or may be included in place of layer 4, or both layers may be present.
Layer 12 is an optional outer coating. Layer 12 can be provided on top of the IR radiation reflective layer 7 and on the dielectric layer (s) 9, 11. Layer 12 can comprise a zirconium oxide, nitride and / or oxynitride and / or aluminum (eg ZrO<sub>x</sub>, ZrO<sub>x</sub>N<sub>and</sub> and / or AlO<sub>x</sub>N<sub>and</sub>) in certain exemplary embodiments of this invention.
The coated article that is made in accordance with the above embodiments (eg, see Figures 1-5) can be used in a GI unit (eg, see Figure 2). The IG unit may or may not be a vacuum IG unit. In other exemplary embodiments, the coated article can be used as a monolithic window unit.
A coated article and / or GI unit made in accordance with the above modalities is advantageous because it can decrease the reflectance of the glass side due to the absorption properties of the absorbent layer (s) to adjust color and / or reflectivity. In certain exemplary embodiments, it may be possible to achieve better selectivity to a given glass side reflectance by increasing the thickness of the reflecting layer of IR radiation (eg silver based) 7. A coated article and / or IG unit made in accordance with certain exemplary embodiments of this invention it may also have improved thermal, mechanical, and chemical durability compared to silver-divided reflective coatings.
It is possible to achieve items coated with reflectance colors on the neutral glass side, green, blue, bronze, golden, etc. It has been discovered that coated articles and / or IG units made in accordance with certain exemplary embodiments of this invention may have the lowest glass (or outer) side reflectance of a silver (or double silver) partitioned coating with the variety of colors of a coated article containing a reflective layer of individual IR radiation.
In certain exemplary embodiments, the desired glass-side reflectance and transmission color can be combined for a desirable film-side reflectance color, which includes a lower film-side reflectance. The inclusion of layers 4 and / or 10 in a low-E layer stack allows the color, reflectivity and solar performance of the coated article to be balanced and adjusted.
Coated articles that are made in accordance with the embodiments of this document are advantageous because clear glass 1 can be provided with a coating 30 that provides the appearance of a mass inked glass - but in fact, the glass substrate 1 it can be a light color or substantially light on its own. By reducing the glass / exterior side reflectance with an absorbing layer to adjust the color and / or reflectivity (4 and / or 10), a thicker 'IR radiation reflective layer 7 is possible. Typically, a thicker IR radiation reflective layer increases the reflectance on the glass side, but the absorbing layer (s) allows for the thicker IR radiation reflective layer 7 without a significant increase in the reflectance of the glass side.
Exemplary modalities with the bronze color (eg, glass-side reflective color) are described above - see Figures 1-5. This section is in addition to the above regarding bronze color modalities. A bronze colored inked coated article may have a visible transmission of from about 10 to 55%, more preferably from about 20 to 50%, and much more preferably from about 30 to 48%. A GI unit that includes a bronze colored inked coated article can still have a visible transmission of no more than about 43%. When the desired tint of a coated article and / or IG unit is bronze in color, layers 4 and / or 10 may comprise or consist essentially of Ni and / or Cr. However, a nickel nitride and / or oxynitride. chrome can also be used for layers 4 and / or 10. Nb, Zr and / or NbZr can also be used in certain exemplary embodiments for absorbent layer 4 and / or 10. An oxide and / or oxynitride of Nb, Zr and / or NbZr can also be used.

In different exemplary embodiments, layer 10 may be present while layer 4 may not be present. In other embodiments, however, layers 4 and / or 10 can both be included in the coating. Layers 4 and / or 10 can be fully or partially nitrided and / or oxidized. Layers 4 and / or 10 in certain embodiments of a bronze colored inked article and / or IG unit may be from about 10 to 150A, more preferably from about 25 to 75A and much more preferably from about 30 to 70 TO.

The silicon-based layer (s) can be deposited by sputtering to a Si or SiAl target in certain embodiments of this invention. Oxygen can also be provided in certain cases in silicon nitride layers.
The above descriptions of the composition and thickness of the layers are not limited to the modalities of a specific color.
Another layer (s) may also be provided under and over the illustrated coating. In this way, while the layer or coating system is on or is supported by the substrate 1 (directly or indirectly), another layer (s) can be provided between it. In this way, for example, the coating of Figure 1 can be considered to be over and supported by substrate 1 even if another layer (s) is provided between layer 3 and substrate 1. Moreover, certain layers of the illustrated coating can be removed in certain modalities, while others can be added between the various layers or the various layers can be divided with another layer (s) added (s) between the divided sections in other embodiments of this invention without departing from the whole spirit of certain embodiments of this invention.

As can be seen above, through the inclusion of an absorbent layer between dielectric layers 3 and / or 5, the glass side reflectance of a coated article can be reduced. The simulated layer stack according to the exemplary embodiments of this invention shows that a 50% reduction in reflectance on the glass side is possible, as well as a less reddish color on the glass side. The color of the film side is also improved. Furthermore, the visible transmission is not substantially affected and the emissivity of 0.03 is good. In the simulation, the low-E coating was applied to a substantially clear glass substrate. The value a *<sub>g</sub> of 1.2 and a b * value<sub>g</sub> 2.8 will cause the coated item to appear bronze in color (but less reddish) when viewed from the side of the glass / exterior. There will be less reflection from the glass / exterior side, which is advantageous from an architectural and aesthetic point of view.

In Example 14, the SiN layer<sub>x</sub> Background was divided and the thin metallic NiCr based layer was introduced as the absorbent layer to adjust color and / or reflectivity. The main function of the NiCr inclusive layer is to reduce transmission and reflectance. Placing this layer between two SiN layers<sub>x</sub> reduces changes in the layer with heat treatment.
In Example 15, a NiCr based layer was also placed between two SiN layers<sub>x</sub> to reduce visible transmission and reflectance on the glass / exterior side. Thickening the NiCr layer (eg 3.4nm instead of 1.0nm or 34A instead of 10) improves the reflected color R<sub>outside</sub> from a positive * value (red) and a slightly negative b * value (light blue) to a negative * value (green) and a notably negative b * value (blue). However, the thickness of the NiCr based layers surrounding the silver layer should be reduced in this embodiment.
In Example 16, the NiCr based layer is reduced from Example 15 and the thickness of the second silicon nitride layer was increased. Although the g value can be increased, this stack has good visible transmission and good reflectance values on the glass side.
Example 17 - Neutral
Another exemplary neutral color inked coating is the following stack, with thicknesses at
Pressure gauges:
<img file="MX2012012166A_D0001.tif" />
The NbZrN<sub>x</sub> it has a refractive index of approximately 2.81 at 550 nm and k is approximately 2.12. The g (Solar Factor) value of this stack is approximately 3% better than one without an absorbent layer and this stack allows the same visible transmission. In this way, selectivity is increased. The t<sub>V</sub>i<sub>S</sub> it is between 41.5 and 44.5 for monolithic coated glass sheet. The reflectance of the glass side is between 19 and 22% and the value a *<sub>g</sub> is between -0.5 and 1.0 and the value b *<sub>g</sub> it is between -4.0 and -1.0. The U value of this stack is between 1.1 and 1.2. An optimal g-value (Solar Factor) for this stack is 0.28.
Example 18 - Blue
A coated, blue inked article was produced. The next stack was sputtered<sub>;</sub>on a 6mm clear glass substrate. The coated, inked blue item was layered with the approximate thicknesses listed below:
