A method for producing a data carrier

The invention relates to a method for producing a data carrier having a transparent plastic layer at least in partial areas, which is provided wenig¬ least in a partial area with a surface relief in the form of a lens structure. Further, the invention relates to a be¬ easily produced by this process disk and an apparatus for performing the method.

It has long been striving media such as Aus¬-looking cards, to provide credit or securities with besonde¬ ren security features, on the one hand have an eye-catching, not copyable visual effect whilst also ensuring a cost-effective production.

From EP 0219012 Al is for example a multi-layered disk having a transparent Deckfo¬ lie known, in which a surface relief in the form of a lens structure is preferred, a Zylinderlinsenra¬ art, is introduced. By this lenticular hin¬ by means of a laser information einge¬ in illustrated unsuccessful volume areas of the data carrier introduced, which are know to er¬ visually well as blackened areas. Due to the effect of the Focus lenses only narrowly limited areas of the data carrier ge be blackened so that the information can only be observed at the viewing angle which speaks ent angle of incidence of the laser on the lens structure. In this way more recognizable only at certain viewing angles information Data are written using verschie¬ ferent marking angle. This effect is hereinafter referred to as "tilting effect".

This tilt image has a number of advantages sicherheitstech¬ cally relevant. So it is, for example, neither photographic nor with copying technology Mit¬ stuffs reproducible because never simultaneously present at a shooting angle all tilt image information. The fake media thus shows only one of information and these at all viewing angles. The Kippbildeffekt has disappeared. In addition, laser marking offers an additional protection against counterfeiting. Because visible changes are attribut- fen that are not chemically or mechanically removed or changed without vollstän¬ ended damage of the media in the laser marking inside the disk material.

This security feature also provides with respect to the economic production of data carriers some

Advantages. Because the caption of the lenticular portion is performed only after the completion of the data carrier, so that in this case any applicable Committee not be¬ schriftet and therefore complicated processes can be avoided with the same data on a downstream trägliches producing a new disk. This applies insbeson particular for the case that the Kippbildinformation is executed based benutzer¬.

The production of the lens structure has hitherto ent neither during the production of the data carrier or upon its completion by impressing with a stamp Präge¬. By heating of the data carrier material and the pressure exerted thereon, however, it is easy to irreparable distortions and to disturbing Durch¬ embossments on the data carrier rear side, which is often used as a printing surface.

Therefore, the lens structures are preferably introduced during the lamination of the data carrier, by one of La inierplatten with the negative lenticular structure is provided. Since the lamination is usually done in the soil nals, the lamination must have the corresponding negative Re¬ relief structure in the region of each individual copy. This has the disadvantage that the entire lamination must be replaced as soon as the area of ​​a benefit an error occurs.

The invention therefore has the object of proposing a drive Ver¬, even in small quantities chenstrukturen with the media without the disadvantages mentioned of the prior art economically and without delays with Oberflä¬ particular lens structures can be provided.

Solutions of these tasks are stated in the claims independent An¬. Further developments result from the respective dependent claims.

According to a preferred embodiment, the relief structure by means of correspondingly shaped spanabhe¬ reproduced tools, such as planing or grinding tools introduced into the data carrier, which consists of a transparent plastic in the area of ​​einzu¬ bring the lens structure. As from microscope cuts ersicht- borrowed, a very smooth lens surface can be produced with good optical quality by this removal method. This method is suitable for all common data carriers, in particular for thermostable materials such as PC, where the usual embossing methods can not be applied. Auf¬ basic material removal of disk ren produced by this Verfah has a relation to the data carrier surface is slightly recessed lens structure, ie, the thickness of the disk is not changed by the lens structure, as in the known tenträgern Da¬ is the case , This circumstance is particularly during stacking, the data carrier according to the invention is of great advantage. By lowering or quasi embedding the lens structure in the disk which is surface Linsen¬ also optimally protected against wear caused by environmental influences.

According to a further embodiment also ein¬ individual embossing matrices may be used, who work th according to a predetermined stepwise heating and pressing cycle in order to avoid distortions of the data carrier material. For this method, a device is preferably used, which comprises several parallel working Prägestatio¬ NEN. During the running of a single disk in the device a stamping die is placed on the disk that is moved port track with the card along a given vor¬ example circular exported Trans¬. During transport through the embosser of comoving stamper is heated in accordance with the predetermined working cycle or after the data carrier was slowly softened and shaped into the desired shape, cooled. The Mitbe¬ because of the heating or cooling device has the advantage that the whole transport time can be used as process time. Alternatively, the heating / cooling device can also be arranged stationary, which has the advantage that the temperature setting can be carried out centrally and stationary for the entire device. The Datenträ¬ ger be here together with the attached Prägestem¬ traffic lights with stationary heating / cooling stations clocked.

The option of being able to control the temperature and pressure cycle in many areas, without major disadvantages hin¬ clearly need to take productivity into account, also makes it possible in this process to produce media in which the lens structure does not increase the media thickness , By the slow Change in condition can deform the disk material very uniformly and without distortions and the überschüs¬ able data carrier material are uniformly distributed over the entire disk.

In order to minimize the risk of distortions on, the data carrier surface can be provided before the stamping process with a lacquer layer that is thermoplastically deformable during the embossing and is only subsequently fully cured. The cured lacquer layer functions here as a kind of fixation for dar¬ unsuccessful thermally softened zone of the data carrier material, which is now without moving after the actual embossing process, cool completely and may harden in the form prescribed by the lacquer layer. However, it is also possible to memorize only in the lacquer layer. In this case, the risk of distortions is completely eliminated, since the data carrier material itself is not claimed during embossing.

In the event that the data carrier will be equipped with a locally be¬ excluded Kippbildelement, kön¬ NEN distortions and wear are also avoided by the Kippbildelement is manufactured as a separate element single and then placed in an appropriately sized recess of the disk.

The production of the lens element can be performed, for example, in a continuous stamping process in which a transparent film is provided in the roller embossing process with the desired structure. It is also conceivable to provide the film already in the extrusion with the ent speaking surface contour. The film is then punched into the individual elements and in the recess of the data carrier, for example by gluing or Welding attached. Another possibility is the injection molding process, individual elements directly to the desired shape can be produced with the.

There are also embodiments possible in which the data carrier or parts thereof are manufactured by injection molding. For example, injection molded ger a Datenträ¬, which has localized on one of its surfaces, the lens structure, to complete their apex regions preferably flush with the Da¬ tenträgeroberfläche. On the gegenüberlie¬ ing side of the disc, a recess is provided below the Linsen¬ structure, in which a rat sepa¬ molded plastic element is used. This element is especially of the requirements

Laser marking adapted by either the elemental material is mixed with additives which the element is coated on the side facing the data carrier with a suitably prepared lacquer layer or absorb the laser radiation.

Another variation is to use a plastic film on at least one injection of an¬ with a translucent layer having in a portion the lens structure. If the film layer on both sides with a Deck¬ provided by injection, then the second cover layer having a structure Linsen¬ in a particular area. In a specific embodiment, the lens structures can be arranged congruently or at least concentrically. If erfor¬ sary, the plastic can be provided with a for the absorption of laser radiation sensitized ized coating in the field of applied lenticular screen before applying the cover sheets. The last described method can completely dispense with complicated and expensive embossers in¬ within the production line of the media. As a result, economic and are manufactured efficiently. Because the production continuously embossed films or injection molding of individual elements can be cost-effective because it can be manufactured in a continuous process at high volume, which must be only the boundary conditions for this process a justice. Problems such as by embossing dispensed onto the back of the data carrier or distortions.

The method of the invention further have the part Vor¬ that they respect their layer structure FER term card can be carried out at the so Ausschu߬ are problems easy to handle. Because in the case of applying an editing incorrectly executed the media concerned can be immediately scrapped and replaced by a subsequent.

Further advantages and advantageous embodiments wer¬ to be explained with reference to FIGS. It is hinge¬ it showed that the figures merely procedural steps outline the essential Ver¬ and are understood neither as complete nor as to scale, of the individual Vor¬ directions.

Fig. 1 shows a data carrier 1 according to the invention. They may be identification card to a single- or multilayer Aus¬ act whose Kartenkδrper is prepared by one of known methods such as extrusion, lamination or injection molding, and with the commonly accepted data 3 such as the name of the user, ei¬ ner account number and general data is provided concerning the aus¬ giving institution. The user-related data is preferably burned with a laser in the interior volume portion of the card, while the general information, such as printed regarding the ausgeben¬ the institution, with printing methods on one of the card layers. Moreover, the data carrier can also have other, only machine-readable data storage devices, such as FEN an integrated circuit or a Magnetstrei¬. The inventive data carrier 1 has correspondingly shown in FIG. 1, in addition to a partial area an optical authenticity feature in the form of a tilt image 2. The Kippbildelement 2 consists, as already explained, a lens structure, wherein may be cylindrical and / or spherical lenses, which adjoin one another, either directly or can be arranged according ei¬ nem predetermined pattern and which are incorporated into a light-transmissive at least in partial areas plastic layer. It can additionally containing the focal lengths of the individual lenses, for example correspondingly to a predetermined pattern can be varied. Of course, the Kippbildelement 2 can also extend over the entire disk. 1

According to a first embodiment, the Linsen¬ structure, introduced by means of cutting tools, such as grinding or planing tools in one of the surfaces of the data carrier.

Fig. 2 shows a grinding cylinders 5, whose surface has the negative relief of the lens structure 4, and with which the data carrier 1 is brought in the region of Kippbild¬ element 2 in contact. The data carrier is thereby pla¬ sheet position between two elements 7, 8, wherein one of the elements 7 in the region of the einzu¬ bring lens structure 4 having an opening. The actual design of the positioning depends on the local conditions and is selected according to these requirements from the known Vor¬ directions.

During the grinding process the edited Daten¬ can be carriers range additionally cooled. FIGS. 3 and 4 show variants in this regard. The grinding cylinder 5 is moved corresponding to the Bewe¬ shown in Fig. 3a transmission cycle on the disk. Meanwhile, the area to be machined is the air conduction system 6, consisting for example applied from a nozzle or a simple tube, with condenser and cold air, as shown in Fig. 3b. Alternatively, look for a Naßkühlungssystem application, whose basic principle is shown in Fig. 4. Again, the data carrier 1 is in a Spannvorrich¬ device 7 is fixed. 8 The grinding cylinder 5 is similar to the cycle shown in Fig. 3a over the Daten¬ moving carrier area and dive during grinding in the grinding fluid 9, in the simplest case water, which provides the necessary cooling. In order to dissipate the heat produced, the grinding liquid 9 with the aid of a pump 11 moves in a closed circuit via the conduit system 10 and simultaneously cooled to the desired temperature again in a cooling system 12th A filter element 13 also ensures that no sanding residue or similar leak back into the Schleifbad. 9

If the lens structure produced by planing 4 by means of a profile chisel, it may however also be necessary to heat the metal-removing tool in order to ensure a good material removal.

Another options gen einzubrin¬ using metal-cutting method, a lens structure to disk, Fig. 5. The cutting part 81 of the milling tool 80 here has the negative shape of a quarter circle on. During the milling process the Werk¬ 80 rotating tool about the axis 82 and is simultaneously moved linearly in the direction of arrow 83 to produce 4, the cylindrical lenses. The cutting portion 81 of the milling tool 80 may alternatively also rotationally symmetrical be¬ respect of the axis to be executed 82 so that the frä¬ sending part 81 receives an umbrella-like shape. Depending on the desired lens shape, the milling tool 80 can selbst¬ course also have any other shape. Also selectable is the geometric configuration of Lin¬ senelements. In Fig. 5, the lens element extends over the entire disk, but it may also be limited locally and executed on the control of the milling tool with any Umrißkonturen.

This method also offers the advantage that both a single card processing and a processing in arc shape is possible. In addition, no Temperatur¬ occurs burden.

According to a further embodiment, the

Disk 1 in any printing process, ins¬ special in screen, gravure or pad printing, are provided with a thin layer of lacquer 14th the lens structure is then reacted with a punch 15 4 transmitted both in the paint layer 14 as well as in the surface area 17 of the data carrier 1 (Fig. 6). The paint layer 14 can be printed either all over or only to a portion of the disk. Depending upon used coating system 14 can be carried out before embossing a pre-curing of the varnish 14, which puts the paint in a thermoplastic state. The complete curing of the lacquer finally takes place during or after the embossing. There can be used from chemically non-reactive components, for example, lacquer systems, wherein the first component dries physically or thermally hardened and the second reactive curing by radiation. By curing the first component creates the necessary for embossing thermoplastic state, which is only canceled by the radiation curing of the second component. However, also component, especially radiation-curing systems Lacksy¬ find application. If the curing during the embossing process, the embossing die for the curing radiation, for example UV or IR radiation must be transparent. The radiation source 16 may in this case be disposed directly in the Prä¬ Die Cut 15, as shown in Fig. 6. However, it can also retard curing coatings are einge¬ sets. Here, the crosslinking process is initiated in the paint shortly before the embossing process by radiation corresponding energy. The complete crosslinking occurs zeitverzδgert so that in the meantime, the embossing can be carried out in the still soft material. When using heat radiation, however, is also sufficient to heat the die to the required temperature. This method has the advantage that the data carrier is not heavily used, because less material must be forced ver¬, which considerably reduces the risk of distortions. Furthermore, the embossing profile in the PVC¬ layer 14 by the radiation virtually fixed lackar¬ tig and thus serves as a kind Fixierhaut for the underlying softened data carrier material, wel¬ Ches thereby to cool after the embossing process without delays.

Another way to reduce the risk of distortions, provides the method shown in Fig. 7.

Here is only marked in the on disk vollflä¬ guages ​​or partially applied lacquer layer 14th In this case, the data carrier material itself is not affected by the embossing process, so that neither supply nor trains by embossing on the back of Datenträ¬ gers may arise.

The embossing of the individual data carrier inventively in a special stamping device that allows a par- alleles processing of each disk. Here, it is irrelevant whether the disk has previously been provided with a fixing lacquer layer as be¬ above written or not. The special Pro¬ process sequence within the device makes it possible, even without distortion inculcate in the media. Fig. 8 shows an embossing device 20 which consists of a plurality of individual embossing stations 21. The nach¬ each incoming volume - in the Figure 8 schematically indicated by the arrow. 22 - be ation of the individual Präges 21 taken, brought into contact with the die located there and zusam¬ men with the stamping station 21 on a circular path to Aus¬ starting point is moved back, where they again leave the embossing device 20 (arrow 23). The transport recke can of course also have any other shape auf¬. The disk must not notwendiger¬, be transported back to the starting point.

During the circulation of the stamping stations 21 are the data tenträger heated slowly, provided simultaneously with the Linsen¬ structure and finally cooled very slowly. Due to the very slow temperature and pressure distortions can practically avoided wer¬ to. According to a first variant, the temperature change is carried out separately in each embossing station 21, ie

Heating / cooling device is the embossing station 21 mit¬ moved and heated or cooled to the present there Prä¬ Die Cut according to a predetermined temperature curve. Al¬ alternatively, the heating / cooling device can also be arranged stationary, wherein for example be on the track 24 heated slowly er¬ during transport Prä¬ Die Cut and media and cooled as slowly back along the transport path 25th In this case, the Präge¬ station 21, which comprises the data carrier with the mounted embossing dies, clocked by the heating / cooling device.

Fig. 9 shows a section along the line 1-1 through an embossing station 21 of the apparatus 20. During the running of the data carrier 1 in the stamping station 21 is of Prä¬ Die Cut 15 is placed on the data carrier 1 and there, as shown for example in Fig. 9, fi¬ xed by a spring 26. Possible alternatives would also pneumatic or electric or hydraulic chucks. The fixing is released only when leaving the embossing station 21 again. The effect of temperature is done via the plunger 27, which is fixed stationary and the heat of the stamper 15, which must be carried out, of course thermally conductive passes. Chine clock with the next Ma¬ the embossing station 21 is transported to the next heating / cooling piston 27th The very long basically process time is thereby intercepted that individually the media and therefore offset each other can be processed. Only at the beginning of the production cycle is a slight machining gap, just equals the orbital period of an embossing station 21st In the further course of the production leaves with each machine cycle a data carrier, the embossing device 20, such as if it had been marked during a machine cycle. The tatsäch¬ Liche process time a Vielz includes ahl on machine cycles, the other allows a distortion-free Ferti¬ supply of data carriers, in particular of Datenträ¬ like, in which to complete the apex regions of Linsen¬ structure with the data carrier surface or slightly recessed relative to the surface are.

A further embodiment of the invention is shown in Fig. 10. Here the disk 1 with ei¬ ner recess 28, for example, is provided by milling or corresponding injection of the volume. 1 In this recess a separately manufactured single element 30 is inserted and connected by gluing or welding with the media. 1 If the single member welded 30 ver¬ with the disk 1 through ultrasonic irradiation, so 30 direction encoder 31, z. B. have on the individual element will see vorge in the form of knobs or strips that concentrate the incident radiation, heat the material locally and thus a controlled welding permit (Fig. 11). These directors

31 made of the same plastic material as the member 30 and can therefore be very beneficial in the spray cast iron are produced together with the element.

Another way of producing Einzelele¬ elements is the embossing of continuous sheets which are then cut into appropriate individual elements. Fig. 12 shows the layer structure of such an endless film 37. A self-supporting plastic film 32 is embossed with the lens structure 4, or already with the structure Linsen¬ extrusion. The underside of the embossed film

32 is provided with an adhesive layer 33, which may possibly be covered with a layer of silicone 34th The embossed side of the film 32 receives a Trenn¬ layer 35 and a covering layer arranged above 36, which protects the lens structure from damage during storage or the punching process. The cover layer 36 may be aufgeräkelt in the liquid state and subsequently hardened. It is of course also conceivable, minting 4 only in certain partial regions rich film 32 provide.

This endless film 37 has the advantage that it stig regardless of the media production herge¬ provides kostengün¬ and in individual elements of any format comminuted cut can be. carrier for the transfer to the Daten¬ the film 32 is either pre-cut or punched di- rectly during the transfer. Then the cover 36 is withdrawn lien radicals together with the non-bonded Fo¬.

The individual elements must of course not necessarily be used in a recess but kön¬ NEN sticks optional aufge¬ on disk surface or be welded. A further variant, ment to provide a card with a Einzelele¬, FIG. 13. In this case, is introduced in the card 1, in analogy to the Ver¬ shown in Fig. 10, a recess 28. It is then injected into this recess 28 by in-mold technology, the lens element, ie, instead of prefabricating an implantable single element the desired shape element is injected directly into the recess 28 of the card 1 and the card surface. The provided with the recess 28 Map 1 is hereby incorporated caster in a spray. In Fig. 12 is for illustrative purposes only, the mold 40 is darge, which must have the negative Linsen¬ structure 42 of course. Via the spray nozzle 41 the translucent or transparent member 43 material is then injected into the recess 28th When casting materials, for example thermoplastics or light-curing, in particular UV-curing plastics are.

The mold may according to another variant also be designed so that the lens structure is not flush with the plane of the surface of the data carrier, but this projects beyond example.

The single element shown in Fig. 14 45 has a slightly more complicated structure than the 11 dar¬ asked in Fig.. It consists of three plastic layers with different properties. The upper layers 46 and 47 are transparent and differ insbeson particular with regard to their absorption characteristics for laser radiation. The plastic layer 46 is substantially transparent to the laser radiation used in the text of the element, while the plastic layer 47 is highly sensitive to laser radiation, that is, the action of laser radiation in the plastic layer 47 hervor¬ a visually detectable color change calls. The different sensitivity to Laserstrah¬ ment, for example, by a corresponding tion Dotie¬ the plastic layers are call hervorge- with soot, with a higher doping gleichbedeu¬ is synonymous with a faster change of Kunst¬ ingredient. To facilitate to er¬ 45 laser inscription of the element, below the layer 47 is an opaque layer 48 is disposed. In the example shown it is only in the central area of ​​the element 45 in place, but they may also be provided over the entire surface of the layer 47th The matching edge areas 49, however, facilitate the attachment of the element 45 in Datenträ¬ eng 1. It is also conceivable to dispense with the layer 48 completely, so that the element has only a 2-layer structure.

The preparation of the element 45 can be carried out in various ways. So it is possible, for example, 45 to generate the single element directly in injection molding. Alternatively, it is also possible, punch out the element 45 construction of an endless two- or three-layer Folienauf¬. In this case, first, in the two- or three-layer terminally losform film structure (46, 47, 48) by known methods, such as coextrusion or

Lamination generated and hen verse¬ with lens embossing. 4 Embossing can either all over or in be¬ voted carried intervals. Thereafter, the excess portions of the film 48 to be milled out, so that the surfaces are formed 49th However, it is also possible to mill in all three layers 46, 47, 48, so that the surfaces 49 are present in the layer 46th Schlie߬ Lich the single element 45 is punched ausge¬ from the endless belt, which operation can be carried out during the bonding with the data carrier first The element 45 may have any geometries of course, pre- Preferably, it has, however, a round or square shape recht¬.

In the event that the element has a round shape, it can be provided with an additional marking in order to enable an exact positioning of the element in the map. Fig. 17a and 17b show two variants ei¬ ner such registration mark. In Fig. 17a, it may be a flattening 61 of the member 60. Also conceivable derecognition 62 as shown in Fig. 17b would be represented. The cards recess has selbstverständ¬ Lich an appropriately adapted shape.

The element 45 is finally inserted into a correspondingly shaped recess 53 of the data carrier 1 and connected inseparably. Fig. 15 shows schema¬ table, the laminated already in the disk 1 member 45 and the heating die 50 in their gegenseiti¬ gen spatial association.

The heating piston 50 is located during the lamination process, only the boundary between data carrier 1 and element 45 on the disk / element laminated on. In the central area of ​​the element 45 50 has the punch, however, a recess 51 in which the Linsenstruk¬ tur 4 protects against damage during the lamination process. Since the data carrier material and the material of the element 45 is softened by the heat and pressure and in existing cavities between data carrier 1 and element 45 flows, is formed in the support area of ​​the punch 50 a seamless surface structure that prevents the element 45 from the disk l dissolved and can be used in a different medium. At the same time arises in the recess below the punch 50 (here an annular region) is an inseparable bond between the disk 1 and element 45, as soften the area of ​​the heating punch the Da¬ tenträgermaterial and the element material into the region of the faces 49th The lens structure 4 is largely destroyed by the laminating process in the support area of ​​the stamp 50th However, the extending member 45 to the composite region having only a width of about 1 to 2 mm, so that only a small part of the lens structure is destroyed. Further distortions can be prevented in the lamination of the data carrier due to the smaller contact surface of the punch. Of the

Stamp 50 may be due to related parties smooth, matt or performed in a different way superficially structured to hide the contour of the transition between element 45 and Kartenkδrper. Further, the non-stick stamp can be coated to prevent bond zwi¬ rule stamps and maps. Alterna¬ tively, it is also possible to use a silicone-coated film as an intermediate layer. To material accumulations in the edge region of the die 50, caused by the displacement of the material in the pressurizing kön¬ NEN to avoid, has the punch in this area 52 the form of a facet.

The bond between carrier 1 and element 45 can be further improved by the opaque layer 48 is provided with an adhesive layer. The adhesive layer may in this case be provided before making Ein¬ zelelements as full-surface layer in the fourth Her¬ position the film structure. An adhesive may be necessary especially if the Ele¬ ment occupies a very large area. The use of an adhesive, it also enables to use different polymeric materials for carrier and element, such as a particularly elastic or easily deformable material for the single element bares and polycarbonate or PETG for the disk. An alternative embodiment provides vollständi- GClick lamination to solely use a Zweikompo¬ nentenkleber. Here, a component is introduced in the recess and the second component to the element.

According to a further embodiment, the element 45 and the recess may auf¬ 53 trapezoidal side contours show (Fig. 16). Recess 53 and element 45 are described regard to their form adapted to each other that the

Element snaps into the recess 53 upon insertion into the card, creating an additional anchoring of the element in the map. The vividness hal¬ about was the overlapping area between a data carrier geroberfläche 54 and element underside 55 greatly exaggerated über¬ shown. In reality, the overlap area a is moved in the order of 100 microns. After insertion into the card^"is the Ele¬ element, as already described with reference to Fig. 15, laminated or bonded to the card body.

According to the embodiment shown in Fig. 18 may also include the data carrier 1 having the lens structure 4. In this case the data carrier 1 is produced as Spritzgußkδrper having on one of its surfaces 65, the lens structure 4th The lens structure 4 ge lying opposite surface 66 is provided with a recess 67, in which an element 68 is used. The molded body of the data carrier 1 is made of transparent or translucent material, whereas the inserted member 68 can be transparent or opaque, and can be stamped out of a sheet or also by injection. The element 68 can be matched to the inside, the card body side facing the special needs of the laser marking. The inner surface can for example absorbing laser radiation sensitive layer are printed, are in which black by the laser beam exposure, kontrastie¬ Area Rende characters generated. About this lacquer layer, which keeps the laser radiation absorbing additives ent, transparent for laser radiation or less sensitive layer can be arranged, which ensures a good bond to the media. Alterna¬ tively can also the plastic material of the element at least partially be mixed with additives which absorb laser radiation. So could be reaching the element for laser marking sensitized for example, only the card body facing Oberflächenbe¬.

In Fig. 19 another solution of the problem according to the invention. Here, the data carrier 1 of an opaque Folieninlett 70, which is 72 provided on both sides with transparent layers 71 in the injection molding process. One of these layers 71 obtained during the injection molding process locally or all over the Lin¬ class structure. Below the lens portion 4 may be provided on the 73 Folieninlett a sensitive for laser inscription layer z. B. ent in the form of a trans-, appropriately prepared lacquer layer.

According to a variant of the data carrier 1 can also beid¬ side with a lens structure 4 and a laser-sensitive layer darunterlie¬ ing 73 provided (Fig. 20). Here, the lens structure regions need not be necessarily disposed congruent to each other, but may be arranged at different locations and with different arbitrary be¬ Umrißstrukturen. In the case of in Figs. 18 to 20 shown is aligned disks, as with most other embodiments of the invention, the lens structure with the surface of the card, so that there may be avoided by the different cartel tendicke problems when stacking the cards.

After the disc is provided by a process according to the invention with a lens structure, it is supplied to a laser marking station. There wer¬ to the Kippbildinformationen ben eingeschrie¬ through the lens structure and into the translucent material. Usefully, the label as part of any case necessary personalization of the data carrier is carried gers, so that under certain circumstances a dividueller for each user in¬ record consisting of directly into the Da¬ tenträger to lasing data and Kippbildinformationen that possibly may also be designed user-related, collected and handed over to the laser control. In case of labeling error, the faulty disk can be immediately discarded and replaced by a subsequent, not yet labeled Datenträ¬ ger with lens structure.

The material, which is provided with the lens structure must at least be translucent course in the field of lenses, so that the passing introduced by the lens information is legible. transparent materials are given to disiloxane used. However, it is also possible to use colored translucent Kunst¬ substances.
