The present invention relates to a kind of novel anthracenpyridone sulfonic acid compound and its preparation method and use, particularly as an anthracenpyridone sulfonic acid compound having a carbonyl compound or a salt thereof or a mixture thereof, and as a magenta colorant.
Of the many color recording methods, inkjet printing is known as one of the most typical. Various inkjet methods have already been developed so far, and most of them realize recording by adhering liquid particles of ejected ink to a recording medium (paper, film, woven fabric, etc.). Since the ink head does not come into contact with the recording medium, it has the characteristics of low noise, compactness, high speed, and easy colorization, and has made remarkable progress in recent years.
Conventional inks are prepared as follows. Prepare ink for fountain pens and brushes by dissolving a water-soluble dye in an aqueous medium and adding a water-soluble organic solvent that prevents the tip from being clogged with ink. Unlike conventional inks, inkjet inks are mainly used for printing high-precision images, and are required to have no head clogging, excellent drying property in a recording medium, low permeability, stable storage stability, and the like. Further, an image printed with an inkjet ink is required to have excellent water resistance, light resistance, moisture resistance, ozone resistance, and solubility, and to have these performances for a long time.
As the shape of inkjet printers evolved from compact printers to large industrial printers, higher water resistance, moisture resistance, light resistance and gas resistance were required. Of these, in the case of water resistance, since porous silicon oxide, cationic polymer, alumina sol or special ceramics can usually be adsorbed on the surface of the base material, a dye is applied to the paper surface together with these organic or inorganic fine particles and PVA resin. By doing so, the water resistance can be significantly improved. Regarding the light resistance, of the four primary colors of yellow, magenta, cyan, and black, the light resistance of the magenta color is the weakest, which significantly affects the image quality, so how to improve the light resistance of the magenta dye is a major issue. It has become. In the case of moisture resistance, when the printed image is stored in a high humidity environment, higher penetration resistance to the dye of the recording medium is required. Penetration occurs in the dye, and especially when high color mixing property such as a photograph is required, the image quality may be significantly deteriorated. However, at present, it is more difficult to improve the light resistance, moisture resistance, ozone resistance and solubility of inkjet ink images than the water resistance.
Moreover, in recent years, with the spread of digital cameras, it has become possible to easily print out photographs even in ordinary households. However, in this case, when the printed photograph or the like is stored, there is a problem that the image is discolored by the oxidizing gas existing in the indoor air. Oxidation gas is a gas that reacts with a dye on or in a recording paper to cause discoloration or fading of a printed image. Among them, ozone gas is known as a main substance that accelerates oxidation and fading of inkjet printed images, and therefore, improvement of ozone resistance is an important issue along with improvement of light resistance.
Typical magenta dyes used in inkjet inks include xanthene-type rhodamine dyes and azo dyes synthesized with H-acid. However, although rhodamine dyes have excellent color and vividness, they have extremely poor light resistance. On the other hand, the azo dye H-acid has excellent color and water resistance, but lacks light resistance, ozone resistance and vividness, and in particular, cyan dyes such as copper phthalocyanine and yellow azo dyes. Compared to, its light resistance is not good enough.
In recent years, anthracene pyridone-type dyes have been developed as magenta dyes that are brightly colored and have excellent light resistance. Since the anthracene ring having a molecular skeleton does not have a carbonylpropylsulfonyl group, it has merits such as bright color, light resistance, and ozone resistance.

However, none of the dyes introduced in these patents satisfy all of vividness, light resistance, water resistance, ozone resistance, solubility, and solution stability. Although some dyes have some improvement in light and ozone resistance, their solubility and stability in inkjet inks, especially long-term stability, remain inadequate. The long-term stability of a dye in an ink is sensitive to the solubility of the dye, and in most cases the solubility of the dye in water is far from ideal.

The mixture obtained by sulfonation and decomposition is salted out or salt converted to form a mixed salt. Salting out or salt conversion is carried out by methods commonly used in the industry. In a preferred embodiment, after sulfonated and decomposed, the sulfonated and decomposed product (mixture) is placed in ice water with stirring and kept at a temperature below 40 ° C. for salting out or salting. Make a conversion and obtain a mixed salt.
Preferably, using an inorganic salt, the obtained compound represented by the general formula (I) or (III) is salted out to prepare a salt. The inorganic salt is preferably ammonium chloride, sodium chloride, lithium chloride or the like or a mixture thereof.
When salting out a sulfonated product (for example, a sulfonated product cooled in ice water) using an inorganic salt, the salting out is performed many times to perform the general formulas (I) and (III). It is preferable to obtain a mixture of salts of the compounds represented by.
Another unrestricted concrete method is as follows: For example, salting out and filtration using sodium chloride can be used to obtain wet cakes containing sodium salts. After dissolving this wet cake in water, add hydrochloric acid to adjust the pH to 1-2, and filter to obtain crystals, which is a general formula in the form of free acid (or partially sodium salt). A mixture of the compounds represented by I and III can be obtained. Next, the wet cake of this free acid is stirred with water, neutralized by adding potassium hydroxide, lithium hydroxide, ammonium, organic amine, etc., and then salted by adding a certain salt. Potassium salt, lithium salt, ammonium salt and organic ammonium salt can be obtained. Of these salts, lithium, sodium and ammonium salts are preferred.
Another unrestricted concrete method is as follows: Add water and lime (calcium hydroxide) to the sulfonated product cooled in ice water and keep the temperature below 40 ° C for reaction. Neutralize the sulfuric acid contained in the system until the pH becomes neutral, form a calcium sulfate precipitate, filter, rinse with water until the filter cake becomes colorless, and combine the filter solution, wash solution, and wash solution. NaOH is added until the pH reaches 12 to 14, and after stirring for 2 hours, the pH is adjusted to neutral with citric acid, and the resulting precipitate is filtered and the general formulas (I) and (III) are used. A mixture of sodium salts of the compounds shown is obtained, then concentrated and separated.
In the present invention, a mixture of salts of the compounds represented by the general formulas (I) and (III) prepared by the above method is subjected to adsorption chromatography separation method, step-by-step salting out separation method, and reverse phase ion pair chromatography. Separation can be performed by adopting a conventional separation means such as imaging.
For example, in the case of reverse phase ion pair chromatography, tetrabutyl ammonium bromide, ammonium tetrabutyl iodide, triethylamine acetic acid and the like are used as the reverse phase ion pair to form a hydrophobic ion pair together with the sulfonic acid group on the dye molecule. Since the polarity of the dye, the number of sulfonic acid groups, and the molecular weight are all different, the adsorption ability of the ion pair to the adsorbent (such as a mixture of octadecylsilaneization) is also different. Therefore, each compound in the mixture can be separated by using methanol water as an elution agent, using a gradient elution technique, and using the sequence of elution order of reverse phase ion pairs in a chromatographic column. As a specific procedure, first, a highly polar, high sulfonic acid group, low molecular weight product is eluted using a solvent with high water content, low methanol (containing 5% methanol, etc.) and strong polarity. Gradually increase the proportion of methanol (from 5% to 100%) to finally separate the less polar, less sulfonic acid group, higher molecular weight products. By setting a different elution order, the eluate can be collected at different time intervals to obtain each separated purified product, that is, a salt of each compound within the range represented by the general formulas (I) and (III).
By desalting the salt of each compound obtained by separation, the compounds represented by the formulas (I) and (III) can be obtained.
For desalting, a method such as a high-pressure reverse osmosis membrane generally used in the industry may be adopted.
In practical applications, this mixture can also be used as is without separation. In the case of a mixture, its application effect may be superior to that of a pure compound because of its high solubility, high color density, and clear color. The mixture may be a mixture of a salt of the compound represented by the formula (I) and a salt of the compound represented by the formula (III), or a mixture of the compound represented by the formula (I) and the compound represented by the formula (III). I do not care.

Furthermore, it can react with benzoyl acetate to form V-RB19 corresponding to intermediate V (R5 is ethyl).
