The present invention relates to a method of manufacturing the media, first of all IDs in the form of maps, securities and the like, when such a data carrier supply protective element having a layer with optically variable properties and effects of laser marking, carrier information, manufactured in this way and to the workpiece for its production.

From the application WO 97/19818 known method of napechatanie on the media, some of the information which color contrasts with the rest of the surface of the media. Then appropriately sealed parts covered with translucent layer with optically variable properties, while the optically variable effect created in this layer is clearly seen only in those areas where napechatannaya information forms the dark and thereby a light absorbing background. Under optically variable effect refers to the ability to create different perceived by the human eye at different angles of view of the visual effects, which, for example, change the color or shades of color.

From DE 19530495 (the closest analogue of the invention) is also known a method of manufacturing a data carrier with an optically variable properties of the protective ale is Tom, having at least one visually perceptible marking and at least one translucent layer with optically variable properties, which at least in some areas covered with markings. The known method is that the media put a translucent layer with optically variable properties and then through this layer with optically variable properties in or marked with a laser layer media the influence of the laser radiation do the marking, while the layer with optically variable properties remains under the influence of laser radiation constant.

The disadvantage of known methods is that to obtain a light-absorbing background and layer with optically variable properties printing must be carried out in several stages, optionally with intermediate intervals for drying. If advectively contains important information you want to protect data, produced by the above method, the media provide only a low degree of protection against forgery and illegal manipulation with them, because napechatannaya information is easily accessible including for illegal manipulation with it.

Based on the foregoing, the present invention was based on the task develo what is needed is a simpler and thus more economical method of making media with optically variable properties of the protective element, and develop manufactured in this way the media, which among other things would have a high degree of protection against forgery and illegal manipulation with them.

This task is solved according to the invention due to the fact that the application of the proposed invention, a method of manufacturing the media on the media put a translucent layer with optically variable properties containing material, creating an optically variable effect.

The object of the invention is also the media, first of all ID card or securities, and preparation for manufacturing. The media has a translucent layer with optically variable properties and a second layer, marked by laser radiation through the layer with optically variable properties. The above marked layer is performed using laser radiation visually discernible marking, and layer with optically variable properties is addressed to the human side marked with a laser layer and at least some areas overlap with this marking. In accordance with the invention it is proposed to use this translucent layer with optically variable properties, which sod is RIT material, creating an optically variable effect.

The influence of the laser radiation in the marked layer, or it can create high contrast and thereby visually distinguishable markings. Are marked on the layer with its appeal to man the parties put translucent layer with optically variable properties. After that marked the layer or by using laser radiation do visually distinguishable markings, affecting laser radiation when performing at least part of the label through the overlying layer with optically variable properties. While the layer with optically variable properties is virtually transparent to laser radiation, and does not change under the influence of laser radiation appropriately selected intensity, the marked layer absorbs the energy of the laser beam, the resulting color is subjected to laser radiation parcels marked layer is changed with the formation of visually distinguishable markings.

To perform the marking can be used laser, the wavelength of the primary radiation is in the infrared or visible region of the spectrum. In addition, since the layer with optically variable properties is translucent, created optical effect in su is the natural enemy impact of the background color. Napechatannaya laser marking is preferably dark, especially black, and, therefore, passing through a layer with optically variable properties radiation substantially or completely absorbed. When observed in reflected light optically variable effect of the overlying layer with optically variable properties, most clearly seen in the plot marks, while the surrounding areas and primarily on a light or white background this layer with optically variable properties virtually invisible.

Because the layer with optically variable properties is transparent to the laser radiation, another advantage of the invention method is that the label on the storage medium can be performed after applying a layer with optically variable properties through him. This makes it possible to produce media unified procurement identical for all media layer with optically variable properties. When this light-absorbing background on which the optical effect layer with optically variable properties, visually perceived most clearly, you can get and at later stages, which allows you to specify the information content is of a light-absorbing marking and to correlate it with specific media only at a later point in time. Due to the simplicity and flexibility of control of laser radiation is proposed in the invention, the protective element can be economical and simple way to provide for each individual media marking, i.e. the individual light-absorbing background.

Proposed in the invention has, in addition, all the advantages which are inherent in the method of laser napechatanie information. When this marking after its corresponding execution on the storage media is not, as is the case with a simple numbering, on its surface, and is reliable and long-term persists in its volume. For this reason, obtained using laser marking is effectively protected against unauthorized manipulation with it, as proposed in the invention, the media in General have a higher degree of protection against forgery compared to the media on which the marking is applied by conventional methods of printing. Laser numbering information is preferably used for the application of data about the owner ID or securities. Proposed in the invention method is suitable primarily for application-specific media personal identification information, such as serial the Omer. Since the operation for personalization or individualization of media proposed in the invention method can be carried out on the last working stage for such an operation for personalization or individualization fall with the appropriate control only defect-free pre-made blanks for the media. If personalization process will fail or crash, this process because it is the final working stage can be repeated with minimal costs across the workpiece from the same batch. In the result, there is no need for extremely time-consuming and thus associated with significant costs to the process of making copies of already equipped with individual data storage media in accordance with the multistage technology of its production and individualization.

Because the individualization of media by laser napechatanie the necessary information you can implement immediately prior to its issuance or delivery in the hands of the user, becomes excessive, in addition, coupled with a certain risk, the transportation or shipment of media between geographically remote from each other paragraphs of their customization and delivery. In addition to this is proposed in the invention method allows you to keep a certain point fewer yet personalized media. Thus, in particular, appears the possibility to store only the required number of media a few basic types, the subsequent marking by which napechatanie on them with a laser, for example, logos, symbols, serial numbers and other similar information, you can split them into smaller subgroups or individual groups or in small batches on the last working stage. For example, organization or enterprise can pre-store in the centre of issuance only one basic type of blanks for the identity of an employee of the company and applying typical for certain groups of employees alphanumeric information or symbols to designate the owner of the certificate to one of the subsidiaries, or one of the branches of this organization or enterprise without the need to maintain for each of such subsidiaries or for each of such branches of certain stock blanks for passes, respectively, semi-finished maps of other types.

General marking characteristics that must be present in all types of media, you can put on them or run into them already on those business operations that precede the personalization process, which consists in laser nadica is Ivanyi necessary information. In this case, to perform similar operations, such as printing a uniform background pattern or picture, you can use the most economical and suitable for large scale production technologies and equipment.

Proposed in the invention method is primarily suitable for the manufacture of such media, as ID cards, membership cards, credit and money cards (cards for withdrawing cash from an ATM), driving license and other securities and counterfeit documents type of banknotes that (the media) are required to provide certain data or information so that they could not be faked by using common tools and that they are protected from illegal attempts to manipulate them. The numbering of the media necessary data using a laser, it is preferable to carry out at last, the final stage of processing before it is released into circulation or delivery to the user, with such laser numbering is primarily suitable for application information designed for personalization of media within the same party or similar media. Made using laser radiation markings may contain information about, for example, is licnosti user, such as his name, date of birth, address, personal or serial number, but may also be a serial number, signature or portrait of any specific logo, information about the rank or title or company logo.

Layer with optically variable properties is translucent. This means that generates an optically variable effect of the materials, and if any additional fillers, binders or carriers are almost transparent at least to visible radiation region of the spectrum and for the primary radiation of the laser used. As materials with optically variable properties you can use primarily net liquid crystal polymers, which can be represented in compact layers or in the form of pigments.

Compact liquid crystal layers to facilitate the handling of them and their application, respectively the introduction, the information carrier is preferably subjected to appropriate processing on a thin transparent polymer substrate and pigments to process together with a transparent plastics film or coating materials. Instead of the liquid crystal polymer to obtain a layer with optically variable properties you can use the interference pigments. But in any case the used pigments or ins is with optically variable properties of the materials should not have, or should have only a minor own coloring or color. To extend the display capabilities and reproduction of certain information can, if given surface, respectively, contour, cover with optically variable properties form alphanumeric characters, logos or symbols. For the application layer with optically variable properties primarily suitable methods such as a method of screen printing, printing method, transfer or pad printing method. For this purpose you can also use foil for stamping.

If the material with optically variable properties are presented in the form of a compact layer, it can be a simple way to paste on the media, what is of particular advantage. In this case, however, the adhesive should provide a permanent bond between the media and glued it to the layer.

Media with optically variable properties of the coating effectively protected from copying using the copy technics, because depending on the angle optical effect cannot be reproduced by using the most common methods of reproduction, such as Photocopying and printing with conventional printing inks.

For protection from exposure to weather, mechanical damage and abrasion layer with optically variable properties PR is doctitle to cover the transparent protective or covering layer. With this purpose, as the outer layer, covering the underlying multi-layer structure is applied a transparent varnish layer or a layer of a polymeric film containing with optically variable properties of the pigments. When using protective films for their reliable and durable connection with the information carrier is preferably applied by hot lamination, providing for the application of pressure and creating a high temperature. Thus, when the lamination layer with optically variable properties is between the basis of the medium and the transparent protective layer.

Layer with optically variable properties can be applied to the entire surface or only on part of the surface of the media.

In another embodiment of the proposed invention, the information carrier can also produce, performing a first stage with a laser marked appropriately and putting then in the second stage layer with optically variable properties. The advantage of this variant embodiment of the invention also consists in the fact that labeling is present in the amount of media protected against forgery.

Other advantages and embodiments of the invention described in more detail below on the example of the preferred options with reference to pilage what's drawings, showing:

figure 1 is a view in plan proposed in the invention of the media, made in the form of maps,

figure 2 - section of a multilayer structure proposed in the invention of the media

figure 3 - section proposed in the invention of the media, made according to another variant, and

figure 4 - proposed in the invention of the media, made in the form of banknotes.

Figure 1 in the form of the plan as an example of the carrier 1 showing the identity card, executed in the form of maps. The basis of such cards sealed General, not individual data 2. Other data 3 on the map contain information about the date of issuance of the document and marked by laser napechatanie. Limited broken line area is covered with a layer 4 with optically variable properties. Through this with optically variable properties of the layer visible napechatannaya laser marking information 5, 6, reproducing the logo 5 and name 6 of the holder. This caused due to the impact of laser marking information 3, 5 and 6 has a black color and has a high coefficient of absorption of radiation in the visible region of the spectrum. The specified marking information due to its visually distinct contrast stands out on a light background the basis of the s or enclosure card. However, the translucent layer 4 with optically variable properties does not occur on a light background and only faintly visible on without marking information sites. This layer with optically variable properties visible to the naked eye and creates different angles of view of different color effects only in those areas where marking information 5, 6 forms for him dark light-absorbing background. When using a special liquid crystal pigments marking information 5, 6 takes, if you look at it at the right angle, for example, green color, and if you look at it under a gentle, respectively, an acute angle, this information takes the blue or black color. In contrast, the total print data 2 and napechatannaya laser date 3 certification always look the same regardless of the angle of view, since such information is applied to some areas not covered by the layer 4 with optically variable properties.

Figure 2 shows the layered structure of the preferred carrier 1 information, which is extremely simple structure. The base or housing of such an information storage device 1 is self-supporting layer 7, which is preferably made of plastic and which can be sensitized for MF is t add to his material in small quantities of substances with a high coefficient of absorption of radiation with wavelength, corresponding to the radiation used to napechatanie laser. On top of this marked by laser radiation layer 7 is a layer 4 with optically variable properties. The influence of the laser radiation through the almost transparent layer 4 in the marked layer 7 "imprinted" dark light-absorbing marking information 6. Depending on the angle optical effect layer 4 with optically variable properties, is clearly seen only in the area where the marking information 6. If marked layer 7 is virtually transparent to radiation with a wavelength lying in the visible region of the spectrum, the marking information 6 in principle can also be applied to exposure to laser radiation from the sides of the data carrier, which is not covered with a layer 4 with optically variable properties.

Figure 3 shown in the cross section of the multilayer structure of the media, made according to another preferred variant, and in this drawing, as in figure 2, presents a fundamental schematic image, which does not necessarily accurately reflect the ratio between the thickness of the individual layers. The information storage device 1, a fragment of which is shown in figure 3, consists of a layer of the substrate 9 (the base layer), which is preferably made in the form of an opaque layer and the em white color. As a material for manufacturing this substrate layer, you can use the first polymer film, typically used in the manufacture of such cards. However, for the same purpose, you can use paper, first and foremost protected from a fake paper. At the layer-substrate caused General print data 2. On top of the substrate layer 9 is marked by laser radiation layer 7, which in this embodiment is made in the form of a thin transparent film. On top facing toward the observer side of the layer 7 provides layer 4 with optically variable properties. This layer 4 is performed by the method of screen printing, for example, in the form of a transparent lacquer layer, which contains pigments with optically variable properties. And, finally, the covering layer is formed outside the transparent protective layer 8, which protects the underlying layers from the influence of atmospheric factors, mechanical damage and abrasion. This protective layer 8 is preferably applied by hot lamination. If necessary to improve the adhesion or adhesion between the individual layers optionally, you can include adhesive layers, especially layers of hot-melt glue. After fabrication of multilayer structures marked in layer 7 by exposure to laser radiation can be performed marking information is July 6, which is inaccessible from the surface of the card, because it is formed inside, respectively, in the volume of the media. Since the layers 8, 4 and 7 are transparent, napechatannaya laser marking information 6, as well as print data 2 clearly visible to the human eye.

Figure 4 shows proposed in the invention, the carrier 10 of the information in the form of banknotes. Sealed banknote substrate preferably made of tamper-resistant paper and sealed commonly used in the technology of printing banknotes methods not individual data 2, which is shown in figure 4 the example is the denomination of the banknote in the form of 500, the portrait and the background pattern or picture. Each bill also contains individual information in the form of its serial number 11, napechatanogo with a laser. At the site, which contains the serial number 11, a layer 4 with optically variable properties. In order to ensure the possibility of laser napechatanie information substrate banknotes, i.e. the basis of the information carrier, at least that section of it, where is the serial number 11, provide marked by laser coating. Such coverage can be obtained, for example, applying a lacquer layer sensitized to the laser radiation, for example, due to added the I to it small quantities of fine particulate pigments. However, there is also the possibility to choose for manufacturing base material or to modify it by introducing suitable for this purpose additives so that it can be directly marked, respectively, directly do you print the necessary information with a laser without causing additional coverage.
