The present invention relates to a multilayer image, in particular, to a multicolor image, comprising a paper substrate and a single - or multilayer structure deposited using conversion film, preferably a film, hot stamping, or laminated films.

The basis of the invention lies in the task of creating a layered image, in particular, a multicolor image on a substrate comprising a paper material, using conversion film, preferably a film, hot stamping, or laminated films. Multilayer image must have a very high protection against tampering. Should also be possible such options, which is optically very interesting, in particular, with regard to a variety of different colors or different optical effects.

This problem is solved in the invention is a layered image according to paragraph 1 of the claims.

Formed in a layered structure laminated image is composed, therefore, of the laser-induced part of the image and the background layer, and laser induced an integral part of the image contains more colors and/or induced by the laser part of the image and the background layer color and/or optical structure is ur stand out relative to each other. Induced by the laser part of the image is an area sensitive to laser radiation layer, which changes under the influence of the laser. Thus, this variable region is sensitive to laser radiation layer forms a so-called laser-induced part of the image. It is located in such a way that overlaps at least partially located underneath the background layer so that the background layer from the top is visible only on the sites and/or visible more or less translucent. Through laser treatment of stretch sensitive to laser radiation layer, that is, by performing laser-induced part of the image you can create a plot of the background layer, not covered with laser-induced part of the image and thus make it visible. The background layer can thus not be closed in areas, so that it can be observed from above.

Induced by the laser part of the image may be performed as a colorless transparent or colored with shades of transparent or opaque marking. Optical particularly interesting and complex images can be obtained in the variants of implementation, which provides that the near-induced laser part and what the considerations applying preferably joining her in the same sensitive to laser radiation layer placed one induced by the laser part of the image, or not processed by the laser region is sensitive to laser radiation layer, or not sensitive to laser radiation region. This adjacent area can be made transparent and colorless, or colored with shades of transparent or opaque. Adjacent areas may have different colors. Each part of the image may be executed as a single homogeneous induced by laser marking, but may also consist of several different located next to each other induced by laser markings.

Especially interesting optical effects get in the variants of implementation, which provides that near laser-induced part of the image, preferably by joining it made an integral part of the image formed in the background.

A high degree of protection against forgery is achieved in variants of implementation, which are induced by the laser part of the image posted with the exact conversion to associated with her part of the image that is formed on a background layer or through it. Preferably in such options is the preferable implementation is provided, what many laser-induced component parts of the image are placed next to each other with accurate conversion, and that the layered image is composed of many of these are located with the exact bringing together the component parts of the image.

Special optical effects get in the variants of implementation, which provides that induced by the laser part of the image is made of colorless transparent or colored with shades of transparent and that correlated with it an integral part of the image located in the underlying layer, placed in relation to this part of the image in the direction perpendicular to the plane of the layers, axial or lateral displacement. If the underlying layer may be talking about, for example, the background layer, which, for example, is designed as a reflective layer with a diffraction structure, preferably located in a limited area.

Possible diverse different ways of implementation, in which the laser induced an integral part of the image is performed, for example, as color markings and/or graphics, and/or as picture captions. A significant advantage of the laser-induced image formation is that induced by the laser part of the image can be performed with very high that is exactly what thew position and with higher resolution, as the laser beam may be picking up an extremely exact position and shape of the marking with the smallest sizes. Induced by the laser part of the image can thus be formed, for example, micronodes or rosette (a pattern of interlocking wavy lines, such as a watermark), or part or sections specified.

To produce laser-induced part of the image may be provided that is sensitive to laser radiation material is designed as a material which under the influence of the laser may vary due to laser-induced bleaching (whitening) and/or laser-induced color change, and/or laser-induced material removal. This change material occurs through laser processing, preferably with specific material and for the corresponding desired effect under laser radiation. Preferably different colors are produced under the influence of the laser for different setting of the laser, preferably at different laser parameters such as laser wavelength and/or intensity of the laser radiation. If sensitive to laser radiation of the material in question may be a dye, preferably a mixture of different dyes. As dye may be used pigments. In the case of pigments it is preferably about insoluble dyes, in particular of inorganic materials. Alternative or additionally as sensitive to laser radiation material can be used and other dyes, such as soluble organic dyes.

Options for implementation, which is particularly simple method can produce a particularly large number of different color markings, provided that at least one area sensitive to laser radiation layer composed of materials is a mixture of pigments, which consists of at least three different components of pigments, each by means of laser can otmelivatsja under particular conditions of laser radiation for the corresponding components of pigments, and moreover, for each of the three components of the pigments is true that under the conditions of laser radiation that is specific to one component of a pigment, other components of the pigments is not bleached or essentially non-bleached. A particularly effective and simple way of forming full-color images is that the formation of laser-induced part of the image is the fact that at the first stage by means of laser irradiation area is sensitive to laser izlucheniya under conditions of laser radiation, specific for one of the components of pigments, bleached only this one component of the pigment, and that in the second step by laser irradiation of the same area sensitive to laser radiation layer under conditions of laser radiation that is specific to one of the other components of pigments, bleached only the other component of the pigment. Induced by the laser part of the images of different colors can be preferably obtained by the fact that sensitive to laser radiation layer consists of a mixture of pigments, and one of the components of the pigment is a blue pigment, another component of the pigment is a red pigment, and another component of the pigment is a yellow pigment. Especially preferred is an implementation option, when the blue pigment is a pigment, bleach red laser light, the red pigment - pigment, bleach green laser light, and the yellow pigment is a pigment, bleach blue laser light.

Additionally, there are options for implementation, which uses pigments or other so-called dye (chromophore) tools or systems that the irradiation of the respective laser radiation change its color, for example, moving from transparency to color or from color 1 to color .

A particularly simple method is implemented in that case, if we assume a layered structure in which the background layer does not contain material which is sensitive to the effects of laser radiation. But it is also possible to carry out the method with a layered structure, in which the background layer contains sensitive to laser radiation material. A particularly simple method is obtained when the layered structure contains only one sensitive to laser radiation layer and only one insensitive to laser radiation layer. Insensitive to laser radiation background layer means that when used in the way the conditions of the laser radiation does not change the background layer.

In preferred embodiments, the implement is provided that is located under sensitive to laser radiation layer, preferably exclusively in the area of AML induced by the laser part of the image, the background layer is performed as reflecting the laser beam used in the formation of laser-induced part of the image, and/or as an opaque or substantially opaque to laser radiation, in particular for non-mirrored portion of the laser radiation, and/or absorbing the background layer. This background layer can, on the one hand, to serve as salt is total induced by the laser part of the image, especially if the said part of the image is color-coded, i.e. with the colored part of the image. Essentially white background layer can be obtained, if the reflection is visible above specific range, has an almost constant high value. Additionally, the background layer can be introduced and special pigments, in particular white pigments, in order to further improve the action as a clarifier or amplifier color. On the basis of reflection and opacity of the background layer for non-mirrored parts used in the laser processing laser radiation, prevents the possibility of damage to the underlying layer or not is another unwanted laser-induced changes during laser irradiation. Thus, the background layer is effective in this sense as a protective layer for the underlying layer or of the underlying layers. Alternative or in addition to the opacity of the background layer, this layer called non-mirrored portion of the laser radiation can be absorbing. In particular embodiments, the implementation may be preferable if this reflective and/or opaque, and/or absorbing the background layer is located only on the site, which is located above it sensitive to laser radiation layer is formed inducere the data laser radiation integral part of the image. Thus it is possible, the background layer outside of this area freely structured to achieve special optical effects, for example, in conjunction with induced by laser radiation integral part of the image. This located externally the area of the background layer can also be sensitive to laser radiation material to form another induced by laser radiation integral part of the image.

Particularly complex form image, if in a layered structure, there are several sensitive to laser radiation layers. They can be separated from each other preferred manner by means located between at least parts of the background layers. Especially interesting optical effects are obtained if the background layer at least in sections has a reflective structure and/or is designed as a reflective layer, preferably as a metal layer, especially a light layer, for example a white layer of varnish. The background layer can also be in areas of the diffraction structure, for example, a diffraction grating, a hologram, Kinegram etc., especially in the metal layer or with him. Additionally or alternatively, the background layer may also have a printed image, at least in areas. Interesting additional effects poluchaets is, if the background layer by its length has different sections, for example, different color and/or different structure. In a particularly simply manufactured variants of implementation provided that the background layer by its length made constantly uniform.

Induced by laser radiation integral part of the image, which occurs under the action of the laser is sensitive to laser radiation layer on the plot, which is sensitive to laser radiation layer is made transparent in the visible spectral range, can be performed as a positive image over the background layer. Alternatively, induced by laser radiation integral part of the image can be formed also by the fact that under the action of the laser is sensitive to laser radiation layer on the plot, which is sensitive to laser radiation layer is made as a covering layer sensitive to laser radiation layer due to laser-induced bleaching, is fully transparent or partially transparent so that the background layer, previously closed sensitive to laser radiation covering layer, in this area becomes visible.

Induced by laser radiation integral part of the image may also be performed in a similar water znakomstvo part of the image, in which under the influence of the laser is sensitive to laser radiation layer on the area where sensitive to laser radiation layer is made partially transparent, preferably colored with shades of layer induced by laser radiation integral part of the image is preferably partially transparent that stands out from the background layer.

Options for implementation with special high degree of protection against forgery get if induced by laser radiation part of the image is performed as micronodes. A high degree of protection against forgery is achieved principally by the fact that the laser operates with high precision register. The laser can be adjusted by determining the parameters for execution of the background layer, preferably definitions printed and/or diffraction image and/or by determination of performance parameters sensitive to laser radiation layer and/or induced by laser radiation integral part of the image, in particular by means of image processing. This preferably can control the position, the direction of incidence of the laser beam, the laser wavelength, exposure duration, number of pulses and/or the intensity of the laser radiation.

In preferred embodiments, execution, especially if you are rabatyvaetsya multilayer image transfer films and/or films, hot stamping, or laminated films, preferably it is provided that when laser processing is changed extremely sensitive to laser radiation layer, and it is preferably only by selective bleaching or selective color change. Preferably suitable additional layers such as protective layers, for example, one or more protective layers remain unchanged, i.e. there is no damage to these layers when exposed to laser radiation. In variants of the implementation using reflected this layer diffused layer preferably is carried out so that at the proper pointing of the laser beam, the latter may pass through and act, if necessary, to lower situated sensitive to laser radiation layer. A particularly high degree of protection against forgery is achieved if sensitive to laser radiation layer or induced by laser radiation markings, when observed in the direction of the multilayer body and/or on a substrate covered with a film placed under the diffractive structure, and/or hologram structure, and/or a reflective layer, and a particular advantage is achieved if the induced laser marking is placed directly adjacent katou above it structure or layer.

Under the reflective layer or reflective field refers to the layer or the area that has a high light reflection and/or high refractive index. While we are talking about a layer or portion which may be made of metal or a metallic compound, for example, aluminum, chromium, silver, zinc sulfide, titanium oxide, etc. are also possible composition of other materials, for example, compounds of germanium, silicon compounds, etc. we can Talk about flat, preferably sputtered layer or areas. Such a layer or sections can be formed in an interconnected or separated from other areas. Also possible implementation in which the property of reflection is provided by the respective particles or the like, for example, using a metal pigments.

Below with reference to Fig. 1-10 describes the film hot stamping and laminated film in a layered structure which can be formed corresponding to the invention of the multi-layer and multi-color image. With reference to these drawings also describes the main stages of the method of laser processing, by which the processed film, i.e. sensitive to laser radiation layer to obtain the appropriate multi-layered image. Instead of films, hot stamping can also be used other transferable film, and described methods can be used to generate appropriate multi-layer and multi-color images.

First will be described the different shown in the drawings, the film that relates to their layered structure and material composition of the individual layers.

In the case shown in Fig. 1-5 films, talking about films, hot stamping. Film hot stamping shown in Fig. 1, includes a carrier film 1, the removed layer 2, protective layer 3, which are sensitive to laser radiation layer 4, the background layer 5 and an adhesive layer 6.

In the case of the carrier film 1 is preferably of a polyethylene film of a thickness of from 6 to 100 μm, preferably a thickness of from 19 to 38 μm. This carrier film 1 placed one above the other layers 2 through 6. They are applied well-known pic is BOM in the manufacture of foil hot stamping.

Remove layer 2 is intermediate (separation) layer. It is made preferably in the form of razmyagchayuschiesya when the heat generation layer, which when applied film hot stamping on a substrate allows to separate the layers from the carrier film 1. Remove the layer 2 usually has a thickness of 1 μm.

A protective layer 3 made in the form of a protective layer of lacquer. While we are talking about a transparent layer of varnish that is designed to effectively protect the free surface decorated foil hot stamping items from mechanical damage and chemical damage. The thickness of the layer is preferably from 1 to 2 microns.

Sensitive to laser radiation layer 4 made in the form of so-called layer paramaka. In this case we are talking about colored pigment and/or provided with other coloring systems, or dyes the varnish layer thickness of preferably from 3 to 10 μm. The pigments and/or other dye or dyes of this layer paramaka selectively bleached and/or change its color to a different color using a laser beam, the wavelength is preferably in the visible range. Preferably, the pigment concentration of this layer 4 of varnish is from 3 to 15% relative to the solid. System of a binder, the layer 4 of varnish should not optically change the od of the laser, so that the irradiated areas occurs only color contrast marking no visible damage to the surface structure. In variants derived from this implementation is sensitive to laser radiation layer 4 has only bleach the pigment or only another bleach the dye and the pigment or dye has as the only pigment or dye, or in conjunction with other pigments or other colorants. In such scenarios, the implementation due to laser irradiation can be formed by the color coding. The same is true for other embodiments, in which instead of bleach pigment or another bleach dye is used, the pigment or dye, which upon irradiation by the laser exhibits a color change, selective laser radiation.

The background layer 5 made in the form of so-called second layer paramaka. This layer is colored differently sensitive to laser radiation layer 4. Layer 5 is, for example, white or ivory, if sensitive to laser radiation layer 4 black or grey. Layer 5 is used primarily as a light background layer for the color formed is sensitive to laser radiation layer 4 by means of laser radiation. The thickness of the layer 5 is preferably in the range from 15 to 20 MK is.

There is an opportunity to provide background layer 5, as well as sensitive to laser radiation layer 4, not on the entire surface of the foil hot stamping and, therefore, not at all the decorated surface in the same location flowers. Rather, the layers 4 and 5 can individually, and thus different, be drawn from the painted different image sections.

In the case of the adhesive layer 6 we are talking about conventional and well-known layer, in relation to bills of films or foils hot stamping, having a thickness of about 1 to 10 μm, and an adhesive layer for film hot stamping has such a composition that it becomes adhesive only at the proper heat.

Transferable film - in this case film hot stamping is preferably applied to the substrate in the usual way, namely, so that the adhesive layer 8 was converted to the substrate surface. The adhesive layer 6 forms then when the hot embossing adhesive bonding with the surface of the substrate. Then the carrier film 1 after softening deleted layer 2 under the influence of heat during hot embossing is removed. When applied in such a way on the surface of the substrate film hot stamping protective layer 3 forms then turned from the substrate upper surface of the exposed film.

It is shown in Fig. 2-4 foil hot stamping have the background layer is made differently than shown in Fig. 1. In the example of Fig. 2 background layer is made as a reflective layer 5r. In the special case of the reflective layer is made as a metal reflecting layer. A reflective layer may be transparent or casticin is transparent for certain spectral ranges. He may have a higher refractive index than the other layers, and therefore has a high light reflection. In the example of Fig. 3 provides a layer 5C as an additional layer of varnish, which is preferably transparent. In addition, a reflective layer 5, which plots has a diffraction structure 5b. In the embodiment according to Fig. 3 this structure 5b conducted as part of the layer 5C varnish and adhesive layer 6, and located between the layer. Alternative or additional diffraction grating can be performed as an integral part of the layer 5C coating or layer 4 paramaka. The diffraction structure may in this case be carried out on sites or as a continuous layer.

In the example of Fig. 4 background layer 5C in a limited area posted by the print image (print) 5d, and sensitive to laser radiation layer with a lateral offset with respect to it is limited sensitive to laser radiation section 4A.

In Fig. 5A shows the film hot stamping with a modified layered structure. The layered structure similar to that shown in Fig. 3, however, the order of layers is changed, namely in such a way that is sensitive to laser radiation layer 4 is turned on from the substrate side of the reflection layer 5r.

In the film according to Fig. 5A layers are located in the following p is the row: supporting layer 1, remove layer 2, protective layer 3, which are sensitive to laser radiation layer 4, an additional lacquer layer 7 and an adhesive layer 6. Performed on both sides of the reflection layer 5r sensitive to laser radiation layers 4 can be made identical, i.e. reflecting layer is then placed in this sensitive to laser radiation of a shared layer. However, sensitive to laser radiation layers can be made different. In adjacent to each other areas sensitive to laser radiation layer 4 and the reflecting layer 5 is made of a diffraction structure 5b. An alternative structure 5b may be performed as a hologram structure. Increased protection against tampering is ensured in this embodiment that two sensitive to laser radiation layer adjacent to the diffractive or holographic structure and can be made equal or different. The lacquer layer 7, which is optional, in this case made as a transparent layer or light background layer. Alternative lacquer layer 7 and the adhesive layer 6 can be omitted, and shown in Fig. 5A under the reflective layer 5r second sensitive to laser radiation layer 4 can be made as sensitive to laser radiation adhesive layer.

In the film according to Fig. 5b layers are in the following order: carrier plait the ka 1, remove the layer 2, which are sensitive to laser radiation layer 4, an additional layer 5C varnish, a reflective layer 5, an adhesive layer 6. Layers 5 and 6 can be made of the same material or from different materials. If sensitive to laser radiation layer 4 in this embodiment, we are talking about a protective layer of varnish, which is made sensitive to laser radiation due to the fact that it contains the appropriate comparable pigments. In adjacent to each other areas additional layer 5C lacquer reflective layer 5 and the adhesive layer 6 is made of a diffraction structure. It can be done as a diffraction grating. An alternative structure 5b can also be made as a hologram structure.

After transfer film, in this case, foil hot stamping, deposited on a substrate, the laser processing is performed to form a sensitive to laser radiation layer 4 is transparent and/or colored marking. To form in a certain position-sensitive laser radiation layer 4 corresponding colour markings, this place is irradiated by laser radiation.

In the case of laser processing film with a layered structure according to Fig. 5 laser irradiation is performed through the reflective layer 5r, including diffractive structure is at 5b. The laser beam is directed preferably from above perpendicular to the film plane. The reflective layer 5 is transparent to laser radiation, especially for perpendicular irradiation. Also diffractive or holographic structure 5b layer, forming in the rest of the area of the reflection layer 5r is transparent to laser radiation, and radiation on the diffraction structure to a greater or lesser extent can also be diffracted or partially reflected. Sensitive to laser radiation layer 4 placed under the layer forming the rest of the area of the reflection layer 5r, even within the diffraction patterns and 5b below, changes under the influence of the laser, at a certain place there is a change in color due to bleaching.

The following describes the bleaching process, as it is shown in the examples of implementation in the respective sensitive to laser radiation layer.

When bleaching at the first stage produces blue or green or red colour marking, while a given area is irradiated by laser radiation with a certain wavelength, whereby certain components of the pigments are bleached. To form a blue color should otmelivatsja yellow pigment component. For this it uses blue laser light To whiten requires a certain minimum intensity. In addition, should not be exceeded a certain pulse width.

So the first step is to get the green color coded, must otmelivatsja red component of the pigment. To do this, use the green laser light. So the first step is to get the red color coded, must otmelivatsja blue component of the pigment. It uses the red laser light.

In order for this site to generate color coded in blue, red or yellow, this area is subjected to laser processing in the second stage, namely laser radiation with wavelength, by means of which on this site is not yet bleached bleached pigment component. If the first stage is formed blue color code on this site is not bleached are the blue component of the pigment and the red pigment component. To elaborate on this site blue color, in this second step should otmelivatsja red component of the pigment. It is a green laser light. Thus in this area is formed blue color marking.

If the second stage instead of this blue markings must be received red colour marking, obtained at the first stage of the blue colour of the markings should be treated with red light laser. Thus, the blue pigment in this teaching is de bleached, so this site remains unbleached red pigment. Therefore, this area formed the red colour marking.

Accordingly obtained from the first stage of the green color marks formed by the remaining unbleached blue pigment and a yellow pigment, to form a blue color coded or yellow color scheme, namely, by treatment with blue light laser or red laser light.

Accordingly, you obtained in the first stage, the red color marking on the second stage to convert to yellow or red color scheme, namely, by laser processing in the second stage green laser or blue laser light.

In order to processed on the first and second stage area to get the transparent area, that is to get a white area, if the background layer 5 is white, the third stage should this site be processed by a laser beam, the wavelength of which is chosen so that the remaining in this area after the second stage unbleached component of pigment bleached, i.e. yellow colour marking should otmelivatsja blue laser, red color marking must otmelivatsja green, and blue color marking should whiten the I red laser light.

In the same way after that is sensitive to laser radiation layer 4 is processed in other adjacent areas to form other colour markings in the layer 4 foil hot stamping. Thus it is possible to produce full-color image.

Laser treatment can also be used to dye or dyes sensitive to laser radiation layer to form a color marking or full-color image by changing color. Laser treatment may suitably be carried out through successive stages of the method. As dyes, i.e. coloring substances may be used pigments. They are often insoluble, and, as a rule, we are talking about inorganic substances. As the dyes can also be used mostly soluble organic dyes. The color change occurs under particular conditions of laser processing, which are used in the laser processing on a separate stages.

Accordingly, the methods of bleaching and color conversion can also be used when sensitive to laser radiation material consists of only one or two components of the dye. In the laser processing can also be used and other components of the dyes and the other conditions of laser processing, in particular, the wavelengths of laser radiation.

Laser processing conversion film or foil hot stamping for forming colored markings can alternatively be carried out before application of the film, namely, if the protective layer 3 is as opaque to laser radiation layer or as a layer that is opaque to laser radiation in a certain wavelength range, or if an additional absorbing ultraviolet radiation protective layer. Laser processing is carried out then before applying the film, while the laser beam is directed on the reverse side of the film, i.e. on the background layer 5, and thus sensitive to laser radiation layer 4 is processed with the other hand to get it color-coded similarly. The background layer 5 and an adhesive layer 6 in such applications are transparent or at least partially transparent for the respective laser radiation.

Accordingly, the color marking can be formed and laminated films. Such laminated film shown in Fig. 6-10. Laminated film 6 includes the so-called covering film 30, an optional intermediate layer 31, which are sensitive to laser radiation layer 40, the intermediate layer 50, brazowski the background layer also which is optional, and an adhesive layer 60. In the process of laminating the laminated film is applied on a substrate facing the surface of the substrate, an adhesive layer 60. Through the adhesive layer 60 is bonded joint with the surface of the substrate. Covering film 30 then forms the upper protective layer, turned from the substrate surface which forms the outer surface of the film. Thus, the covering film 30 and remains there after the application of laminated films. It corresponds to the protective layer 3 film hot stamping according to Fig. 1. Sensitive to laser radiation layer 40 corresponds sensitive to laser radiation layer 4, that is, the first layer 4 of the lacquer film hot stamping of Fig. 1. The intermediate layer 50 corresponds to the background layer 5, that is, the second layer 5 of the lacquer film hot stamping of Fig. 1. Adhesive layer 60 corresponds to the adhesive layer 6 foil hot stamping of Fig. 1. Laminated film of Fig. 7 and 8 are variants of the laminated films according to Fig. 6, in which the background layer is changed accordingly, as the background layer in the film hot stamping shown in Fig. 2 and 3.

Laminated film according to Fig. 9 has a layer structure with a modified compared with Fig. 6-8 order placed one above the other layers. The sequence of layers which corresponds to the structure of the film hot stamping according to Fig. 5. Here, the layer 70 is an optional background layer.

In Fig. 9a shows a variant, modified compared to the embodiment according to Fig. 9, with the sequence of layers corresponding to the structure of the film hot stamping of Fig. 5A.

Laminated film shown in Fig. 10 is a variant of laminated films according to Fig. 9. In this embodiment, the covering film 30 has a deposited film hot stamping. This applied where the film hot stamping replaces provided in the laminated film of Fig. 9 layers 31, 50 or 50r, 40, 70 and 60 corresponding layers of film hot stamping. In the case of film hot stamping used for manufacturing this laminated films, unlike film hot stamping according to Fig. 5, the reflection layer 5r and sensitive to laser radiation layer 4 is posted in reverse order, so that in the case of laminated films according to Fig. 10, in accordance with the fact, as in the case of laminated films according to Fig. 9, the reflection layer 5r posted on turned from the substrate side is sensitive to laser radiation layer 4. In accordance with the fact, as shown in other embodiments, implementation, adjacent to other areas of the layers 4 and 5 in the laminated film of Fig. 10 is made of a diffraction structure 5b. The lacquer layer 5 while the imp is replaced as a transparent layer.

Laminated film according to Fig. 10A is similar laminated film according to Fig. 10. In the embodiment according to Fig. 10A covering film 30 has a deposited film hot stamping, which is shaped similar to film hot stamping in the embodiment according to Fig. 5A. This tape hot stamping, printed on the covering film 30, replaces provided in the laminated film of Fig. 9a layers 31, 40, 50, 50r, 40, 70 and 60 corresponding layers of film hot stamping. Laminated film according to Fig. 10A is a sequence of layers that is located in the following order: covering film 30, an adhesive layer 6, an optional layer 5 of varnish, sensitive to laser radiation layer 4, a reflective layer 5r, sensitive to laser radiation layer 4, an additional layer 5C varnish and protective layer 3. Performed on both sides of the reflection layer 5r sensitive to laser radiation layers 4 can be made identical, i.e. reflecting layer is then placed in this sensitive to laser radiation of a shared layer. However, sensitive to laser radiation layers 4 can be performed and different. The lacquer layer 5 is made as a transparent layer or as a light background layer.

Laminated film according to Fig. 10b is an implementation option, in which the covering film 30 also on esena foil hot stamping. This caused the film hot stamping is made like a film shown in Fig. 5. It replaces provided in the laminated film of Fig. 9a layers 31, 40, 50 or 50r, 40, 70 and 60 corresponding layers of film hot stamping.

Laser treatment of the laminated films is carried out appropriately, as described for film, hot stamping, i.e. by the corresponding serial whitening or sensitive to laser radiation color change of the dye contained in the sensitive to laser radiation layer 40, that is, components of pigments or other sensitive to laser radiation dyes.

The following describes embodiments of multi-layer images, shown in Fig. 11-30, which may be formed by laser processing using a variety of films shown in Fig. 1-10. Presents a layered image are composed, respectively, of the laser-induced part of the image formed in the sensitive laser emitted is th layer, and part of the image formed by the background layer or above him the foreground image. Fig. 11-30, which show various embodiments of the formed multi-layer images, are using types in cross section substantially schematically sensitive to laser radiation layer 4 at the top or bottom layer of the film and placed underneath or above the background layer 5 at the bottom or top layer of the film. In the presented schematic images shown, respectively, only one sensitive to laser radiation layer 4 top or bottom film layer and only one background layer 5 of the lower or upper layer film. Appropriate other layer of the layered structure and the corresponding adjacent layers, as well as above - and the underlying layers and other layers corresponding film for simplicity is not shown. Preferably the reflective layer is placed directly on or under sensitive to laser radiation layer.

In the first embodiment shown in Fig. 11a-d, coming from film, in the case which is sensitive to laser radiation material contained in the reservoir film layer 4 in a limited area 4A. Region 4A in Fig. 8A and b, which show the state before laser processing is a rectangular field. Feelings is positive to laser radiation material can also be modified variants of implementation to run on the entire surface or on a larger area of the reservoir film. The background layer 5 in the shown embodiment, contains a printed image 5d, which is placed in the reservoir of the film under sensitive to laser radiation region 4A. Sensitive to laser radiation region 4A covers printed image 5d. Sensitive to laser radiation layer is made as a more or less fully optically covering (shielding) layer, which is located underneath the print and the 5d image before laser processing from the top is invisible or only more or less translucent. Sensitive to laser radiation material preferably black or grey, or has, in particular, dark, in any case more or less covering color. Through laser processing film, based on the state shown in Fig. 11a and b, sensitive to laser radiation layer, i.e. in the area 4A, by means of laser-induced bleaching or laser-induced color change is produced marking, in the example according to Fig. 11C and d transparent marking in the form of A. due to this marking is located underneath the printed image 5d in marking freely observed or observed translucent to a greater or lesser extent. In this way we obtain a marking, which may be of any color or multi-color representation, depending on C the ETA form or complete a printed image of the 5d and depending on the degree of transparency or coloring region labeling in layer 4A. In any case, get an image that is combined from laser-induced part of the image and educated background layer integral part of the image. Induced by the laser part of the image in the case shown in Fig. 8 variant implementation is a negative image, consisting of region 10, more or less transparent due to laser processing, and the property around it is not processed by the laser covering the area sensitive to laser radiation layer 4A. Another integral part of the image formed by the free, because of changes sensitive to laser radiation layer, the background layer, i.e. the free area of the printed image 5b.

In the embodiment shown in Fig. 12, we are talking about the image formed accordingly. The only difference compared with the embodiment shown in Fig. 11a-d, is that of Fig. 12 printed image 5d formed in the background layer has the characteristic of changing color and so after the treated area is marking with a corresponding change in color.

A third variant embodiment of the invention, which is shown in Fig. 13A-13d, implemented and structured appropriately, as shown on the I variant implementation according to Fig. 11 and 12. The only difference is that, in comparison with the embodiment according to Fig. 11a-d, the background layer instead of the printed image to the 5d has a diffraction pattern 5b. The diffraction pattern 5b may be made in the metal layer with an appropriate surface quality and/or in the layer of lacquer and covered with a metal layer. Option implementation according to Fig. 13A-13d, due to visible in marking 10 diffraction pattern 5b, is particularly interesting optical effect. In this way it is possible to create individualized diffraction patterns, because the diffractive structure is visible only in the field of laser-induced part of the image. In modified embodiments, the implementation is sensitive to the laser radiation region 4A and the diffraction pattern 5b can be placed with a lateral offset relative to each other, that is not fully aligned one above the other, as shown in the variants of the implementation shown in Fig. 13A-13d. This version of the implementation shown in Fig. 14a-14d. The background layer 5C or 50 contains a limited area 5b of the diffraction pattern in the entire area is designed as a reflective layer or contains a reflective layer. The region with the diffraction pattern 5b is not aligned under sensitive to laser radiation region 4A, and when the observation direction is perpendicular is about to the film plane with a lateral offset. Coaxially under sensitive to laser radiation region 4A reflecting layer does not contain the diffraction pattern 5b, and has a matte metal or metallic glossy plot. Sensitive to laser radiation region 4A coated with various marking 10 with a laser, namely, by means of laser-induced bleaching or laser-induced color change. Corresponding to the treated areas 10 be as a consequence more or less transparent. Location-based with lateral displacement of the diffraction patterns, depending on the angle of observation, in the field of labels 10 can produce different effects, in particular, different color forms. Thereby, it is possible to form a special encoding.

In the described embodiments, the implementation shown in Fig. 11-14, laser marking 10 can be performed by an appropriate guidance of the laser beam in the laser processing simple way in any form. For example, can be formed letters, labels in any shape and any size, for example, certain private labels. But also marking can be implemented as any graphic form. Due to the application of different conditions of laser processing at different sites can be formed by marking with different degree is otbelivanie or multicolor labeling.

In addition, embodiments of, respectively, Fig. 11-14 possible as lottery cards, the amount you win in the manufacture of film is printed on the background layer 5, which is applied to the layer of film sensitive to laser radiation layer. Alternatively, the winning amount may be printed on the substrate, which layer is applied. Using a suitable laser device, i.e. when the specific conditions of laser processing, sensitive to laser radiation layer may then otmelivatsja, thereby making the winning amount visible.

In the embodiment shown in Fig. 15A-15d of Fig. 15A and b originate from the structure of the layers, which corresponds to the layer structure of the above-described variant of the implementation according to Fig. 12-14. However, in contrast to this, in the embodiment according to Fig. 15A-15d sensitive to laser radiation layer 4A laser processed outside area surrounding the marking. Due to bleaching or color change, this area becomes transparent or translucent. In this embodiment, the resulting image is composed, therefore, as shown in Fig. 15C and d, of the residual region 10r, remaining sensitive to laser radiation layer - Fig. 14C and d formed in the form of the letter a from the outer region, the transparent due to bleaching of the OS is the real sensitive to laser radiation region 10, through which visible printed image 5d.

In the embodiment shown in Fig. 16A-16d, the marking is produced by the method similar to that used in the embodiment according to Fig. 15A-15d. In this case, sensitive to laser radiation layer 4A is made, for example, as a green covering layer. By selective bleaching at different wavelengths of laser get different colored marking 10x, u, 10z. Green sensitive to laser radiation layer by irradiation of laser light in the blue spectral range is changed to blue, but due to the irradiation of the laser light in the red spectral range is changed to yellow. By sequential or simultaneous application of the two wavelengths outside area 10 fully bleached, i.e. running as a transparent area. In this embodiment, the formed image is an inscription in the form of a name consists of the name of 10x and part of the name 10y, underlined by the structure of the lines 10z. The first word "Peter" can be formed as described above as the blue label and the second word, in this case "Müller", as the yellow label, and the structure of the lines in green lines. Located around these markings region 10 fully bleached, so that this area becomes visible in the background layer is a diffraction pattern 5b or printed image, etc.

An implementation option, shown in Fig. 17A-17d, modified in relation to the alternative implementation of Fig. 16A-16d in such a way that is sensitive to laser radiation layer 4 placed on the facing substrate side diffraction patterns 5b, and therefore the diffraction structure covers the laser-induced marking 10. This ensures a higher degree of protection against counterfeiting, in particular, if one is sensitive to laser radiation layer made laser-induced marking is directly adjacent to the diffraction structure 5b or is itself part of the diffraction patterns.

In the embodiment according to Fig. 18a - 18d in the case of Fig. 18a and 18b extend from the film, which is sensitive to laser radiation layer 4A is translucent green. By selective bleaching or selective color changes may be formed is shown in Fig. 18C and 18d image, similar to watermarks. It consists of a translucent color patterns of lines, namely, translucent blue line 10x and translucent yellow line 10y. The corresponding line is formed through individualized micronodes 10xs, 10ys. Line 10 can also be formed blue micronodes, and the line u yellow micronodes. In the shown embodiment, prospecive is the one blue line 10x should consist of micronodes as ordered sequentially name "Peter Mü ller", and translucent yellow line u from micronodes as ordered in line dates "20.4.2000, or any other personal data. The area is sensitive to laser radiation layer 4A outside the lines 10A and 10b in this embodiment, fully bleached by laser treatment, but also due to the particular laser treatment to stand out, prosvechivali, regarding the structure of the lines by coloring in a different color.

In the embodiment shown in Fig. 19, in contrast to the variant according to Fig. 18, extend from sensitive to laser radiation layer is made in the form of a colored transparent layer, for example, as a green transparent layer. Sensitive to laser radiation layer 4A by means of laser-induced color change is formed inscription. The inscription consists of blue and yellow parts.

An implementation option, shown in Fig. 20A and 20d, is modified compared to the embodiment according to Fig. 18a-18d in such a way that is sensitive to laser radiation layer 4 placed on the facing substrate side diffraction patterns 5b, and the diffraction structure covers induced by laser marking 10x, u. In the rest of this alternative implementation is shown in Fig. 20A and 20d corresponds to the version of the implementation in Fig. 18a-18d.

A variant of the implementation of the population, it is shown in Fig. 21A-d, based on the use of film, which is sensitive to laser radiation layer 4A is made more or less cover (mask) in green or another color in area 4A. The background layer 5 is in the underlying region of the reflective layer is separated from other areas of the diffraction pattern 5b. By means of laser radiation with precise guidance on the situation sensitive to laser radiation layer 4A are separate marks in the form of alternating, spaced from each other a square field 10x and u. Through appropriate laser treatment under various conditions is achieved that the field is 10x blue, preferred blue, and the field u is yellow. The area around the field 10x and u not subjected to laser processing and remains in its original color, e.g. green. Due to the precise targeting on the position of the laser beam to perform field 10x and u with exactly defined locations relative to the diffraction fields. Field 10x and u are more or less transparent, so that on the basis of light diffraction on the diffraction structures 5b arise colour shades depending on overlapping at every moment of colors is dependent on the wavelength of the reflection of emitted light. Due to the fact that the background layer 5 contains cerebus the Xia, located coaxially with the laser induced fields 10x, u, diffraction pads 5b and metal mirror sites, in cooperation with painted due to laser irradiation sites occur representation of the image, changing depending on the angle of irradiation and observation.

In the particular implementation shown in Fig. 21 variant implementation can be provided that the metal layer is made only on the separated individual plots 5r as a reflective layer, and the rest of the area is designed as the structure of the lattice. Sensitive to laser radiation layer can be irradiated with a laser so that the alternating field 10x, u was otbelivanie different way, that is acquired different color. These fields 10x, u, forming a laser-induced colour markings can be placed in such a way that they are, when seen in a direction perpendicular to the plane of the layer, are arranged coaxially above the reflective fields 5r. Depending on the angle of illumination and observation, with out changing optical effects.

In the modified embodiment shown in Fig. 22A-22b, sensitive to laser radiation layer 4A by means of laser bleaching is performed in a circular field 10x and u in alternating sequence with razlichnyje. They are, when seen in a direction perpendicular to the plane of the layer coaxially above the diffraction fields 5b, which in the top view also have a circular contour. Diffraction field is performed in the reflective layer, which is located under sensitive to laser radiation layer 4, preferably directly below it. Option implementation according to Fig. 23a-23d modified in respect of option implementation according to Fig. 22A-22d in such a way that the circular reflecting field 5r placed in the diffraction structure 5b, and laser-induced circular color field 10x, u located coaxially above the reflective fields 5r.

In the case of the variant of the implementation shown in Fig. 24A-24g, proceed from the film, in which the partially transparent reflective layer 5 is over sensitive to laser radiation layer 4. Sensitive to laser radiation layer 4 made in more or less cover (mask) layer, for example, green or other color in area 4A. A reflective layer 5 contains plots of the diffraction structure 5b, and separated from each other separate fields 5r reflecting layer 5 is made as a flat layer without diffraction patterns. A reflective layer 5 applied by spraying directly onto sensitive to laser radiation layer 4. The diffraction structure 5b to perform the s in the reflective layer sensitive to laser radiation layer 4 and lasts sensitive to laser radiation layer 4.

By laser irradiation through the reflecting layer 5 exclusively in the field of flat reflective fields 5r when the exact position pointing the laser head are formed accurately located in the underlying sensitive to laser radiation layer 4 separate marking in the form of alternating spaced from each other a square field 10x and u. These laser-induced marking in the form of a square field 10x and u are located in the embodiment according to Fig. 24 respectively coaxially and accurate wiring according to the size and location under the flat reflecting fields 5r reflecting layer 5. By an appropriate laser treatment under various conditions is achieved in that field 10x and u are in different color, for example, field 10x are blue, and the fields a yellow. The area around the field 10x, u not subjected to laser processing and retains its original color, e.g. green.

Based on the light diffraction on the diffraction structure 5b, in conjunction with various colors field 10x, u, there are changing color hues, which depend on the type of radiation and the angle of irradiation and observation. Thus are formed respectively changing the representation of the image. A diffraction pattern or laser-induced color image becomes alternately and the changing, for example, in the case of oblique movement of the film from which the irradiation angle and/or viewing angle changes depending on the light source, as schematically shown in Fig. 25A and 25b. In the position according to Fig. 25b areas 5r are presented in color, and the diffraction structure is not valid. In the position according to Fig. 25A, on the contrary, the diffraction pattern is observed and is superimposed at least partially on the coloured areas.

Option implementation according to Fig. 26a-26d modified in relation to the alternative implementation of Fig. 24A-24d so that the diffraction field 5b is performed in the reflective layer 5r, placed over sensitive to laser radiation layer 4, and induced by the laser field 10x, u made with the exact combination of position under the diffraction fields 5d, and are aligned with one another diffraction field 5b and induced by the laser field 10x, u respectively have a square base.

In the embodiment shown in Fig. 27, sensitive to laser radiation material layer 4 is placed in a limited area, in the area of rectangular shape. Layer 4 outside the region 4A is transparent so that the printed image is made in this area in the background layer 5d is visible. Printed image 5d may be performed in a separate background layer of the multilayer film or can be done is but directly on the surface of the substrate. In the case of the printed image 5d we are talking in this case about verbal image Bank von Island" and the verbal image "Pass-Nr". The last placed between two parallel, also printed or fictitious, that is, mentally spent the lines alignment 5df, with a fine cast.

Due to the accurate position of the pointing of the laser beam can continue applying labels with accuracy in the micron range relative to the printed image 5d sensitive to laser radiation region 4A by selective bleaching or selective color change. When this marking is formed, which continues both lines alignment 5df printed images that are located on both sides of the sensitive to laser radiation field 4A or exist only as a dummy, i.e. mentally drawn line alignment, zone 4 as an induced laser line alignment 10f. Between the lines 10f is formed with an exact conversion corresponding induced by laser inscription 10x, u, in the shown embodiment, the sequence of digits"5 7 6 4 9 3 7". While individual figures 10x, u can be made in different color and respectively represent the characteristic color change, for example, due to different bleaching or different color changes on different participants is Oh, or based on the run beneath them, if necessary, translucent printed image. Separate figures 10x, u can be performed by micronodes. Due to this, may be provided with a high degree of protection against forgery.

Option implementation according to Fig. 28 modified compared to the embodiment according to Fig. 27 thus, to increase the degree of security over sensitive to laser radiation layer 4A posted by diffraction structure 5b. It can be executed directly adjacent to sensitive to laser radiation layer, for example, in the reflecting layer, which in this limited area napalan, or in the reflective layer that covers the entire depicted in Fig. 28 surface structure in this embodiment. This reflective layer in the present embodiment, performed only on the site, covering sensitive to laser radiation field 4A, in the form of a diffraction structure, which is also transparent. Laser processing is carried out by laser irradiation through the reflecting layer or the diffraction structure 5b. In a similar manner as in the embodiment of Fig. 27, thus formed laser-induced marking with accurate casting. Due to the fact that over the laser-induced marking in VA is iante implementation according to Fig. 28 posted by diffraction structure, which is directly linked with the corresponding layer, which contains the marking, provides an increased degree of protection against forgery.

In the embodiment shown in Fig. 29A and 29b, also implemented by providing accurate casts correlation diffraction fields induced by the laser colored patches, and that an implementation option as laser-induced image a contains full-color portrait image formed by a laser processing. Induced by the laser in the image is sensitive to laser radiation layer 4. Provided by diffractive elements 5b, which are made as gelosi and supplemented with an accurate cast adjacent induced color Gelosie 10x. This structure, consisting of a adjacent to each other arcuate sections, made with alternating as diffraction gelosi 5b and laser-induced colored gelosi 10x placed in the form of a closed circle around the laser-induced portrait image u. In the marginal areas of laser-induced color images we additionally performed diffraction gelosi 5b in the shape of a snake, which cover the areas of laser-induced image u.

The layer structure of variationbetween, presented at Figo and b, similar to the structure in the embodiment according to Fig. 28. Over sensitive to laser radiation layer which contains laser-induced image u and laser-induced gelosi 10x, are elements 5b diffraction patterns. They are preferably located in the layer in a remaining area of the reflection layer 5r, but can be performed solely and directly sensitive to laser radiation layer 4A.

Laser processing for forming a laser-induced full-color image W and colored gelosa 10x is carried out appropriately, as in the above described embodiments implement.

In Fig. 30 shows an implementation option, a variant on option implementation according to Fig. 29. It also features a laser-induced portrait W, which is performed as a full color image. But instead induced by laser kilosa and diffractive elements in the embodiment according to Fig. 29 on the four edges of the portrait image u are diffractive elements 5b star-shaped in such a way that they are his one and a half go to the appropriate regional area of laser-induced color images u, and their other half go in the area surrounding the Yu-induced laser image u, standard stamp or seal, confirming the authenticity of the document. The structure of layers in the embodiment according to Fig. 30 can be performed similarly to that found in the embodiment of Fig. 29A and 29b. The structure of the layers can be formed, deposited on a substrate film, it is preferable conversion film, and on the facing substrate side posted sensitive to laser radiation layer made induced by laser portrait image u, and diffractive elements 5b posted on turned from the substrate side is sensitive to laser radiation layer and thereby cover and cover with a laser-induced image u. Embodiments of Fig. 29 and 30 may refer to a personalized ID cards. In the embodiment of Fig. 30 as signatures induced by laser portrait image u applied the name "Tamara Testfrau" in laser-induced marking, preferably multicolor. The inscription can be done by the microlettering to improve the protection against forgery.

In Fig. 31A and 31b shows an implementation option, a modified relative to the embodiment of Fig. 29 and 30. This implementation provides for the carrier, forming a substrate made of paper material, which caused plait the ka hot stamping, which, as shown in cross section in Fig. 31b is only sensitive to laser radiation layer 4 and the upper protective layer 3 and has an adhesive layer 6, which represents a connection to a surface of the substrate. Sensitive to laser radiation layer 4 as the laser-induced image made full color image similar to that shown in Fig. 29 and 30. Unlike the previous embodiments, the layer structure of the film hot stamping is not provided the background layer 5. On the contrary, the background layer is made on the surface of the substrate 8 as a separate coating 315 or as an integral part of the substrate 8. In this case we are talking about the different characters that respectively rayed through laser-induced image u, namely, protective seal 315d, which may be performed as gelosi and the like, and fluorescent threads 316, which, for example, can fluorescamine in ultraviolet radiation and daylight are not visible or are represented as black strings. In addition, the carrier 8, preferably consisting of a paper material made watermarks. In addition, the carrier 8 is placed protective strip 310, which crosses the laser-induced image u and continues in the area where no laser-induced depicts the e u. Induced by laser image u in the shown embodiment, is rectangular and is placed only on part of the surface of the carrier 8. Preferably the transfer film that is sensitive to laser radiation layer 4, which is also made in this limited area. Rectangular region of the laser-induced image a, as shown in Fig. 31A is transparent, that is, the specified area is sensitive to laser radiation layer by laser processing bleached so that the colored portions of the image become transparent painted, and the area around labels bleached to fully transparent. This provides the advantage that existing on the substrate 315 marks visible through laser-induced image u. This achieves a particularly high degree of protection against forgery.

In Fig. 32 shows an implementation option, a modified relative to the variant according to Fig. 31A, b. In contrast to the implementation according to Fig. 32, in the area of laser-induced image u made the background layer 5. This background layer 5 is part of the conversion film. Thus, unlike film according to the variant according to Fig. 31b, in the embodiment according to Fig. 32 used film, p is the established levels which corresponds to the film, shown in figure 1. The background layer 5 is made on facing the carrier 8 side of the film and thus when applied on the substrate film is between sensitive to laser radiation layer or laser-induced part of the image and the surface of the substrate. The background layer 5 covers in this area placed on the substrate and in the substrate marking elements. The advantage of the background layer 5 is that the laser-induced image is very distinct and the formation of laser-induced images may not cause damage to the substrate or located underneath layers. The background layer 5 is reflective for the laser radiation used to image formation, and for non-mirrored portion of the laser radiation is substantially opaque and absorbing. Thus, when the laser irradiation in order to form a laser-induced image u damage or other unwanted laser-induced changes of the background and the substrate are eliminated. Due to the reflection of the background layer 5 and preferably by adding a special whitening ingredients color effect induced by laser image is enhanced, and the color is preferably lightened.

In Fig. 33 shows an implementation option, a variant on option on the IG. 31 and 32. In the embodiment according to Fig. 33, only the left half of the laser-induced image u is the background layer 5, so that only left in this partial area, which made the background layer 5, marking 315 on the substrate 8 is covered and not visible. In the rest of the field induced by laser image a background layer is absent, so in this area colored transparent laser-induced color image u viewed through the surface of the substrate, and accordingly is visible marking 315. In this embodiment provides a particularly high degree of protection against forgery, as the laser-induced image u especially diverse optically interacts with the rest of the marks.

Sensitive to laser radiation layer 4 in modified embodiments, the implementation can also be performed as a layer under the action of laser radiation only blackens, for example, as a layer with an impurity of carbon or soot. It can carboniteservice under the influence of laser radiation, in particular Nd:YAG laser with a wavelength of 1064 nm. Due to this, you may receive the image grayscale, if the conditions of laser radiation, preferably laser power, irradiation vary accordingly.

In Fig. 34 on the azan card structure in view of the diversity of elements. We are talking about the base, laminated on various covering film 30, 32 and the insert 90. Insert 90 can preferably consist of a paper material, but can also be made of synthetic material. On the top of the insert 90 is placed alloyed with carbon or soot covering film 32, which is applied to the covering film 30. This covering film 30 corresponds to the structure of the laminated film, as shown in Fig. 10. It has a carrier film 30, on the lower side which caused the transfer film, preferably a film, hot stamping, which contains an intermediate layer 5C and the reflection layer 5r and sensitive to laser radiation layer 4. In the reflecting layer 5r and sensitive to laser radiation layer 4 is made of a diffraction and/or hologram structure 5b. Not shown in the drawing modification options corresponding to Fig. 33, between sensitive to laser radiation layer 4 and alloy covering film 32 can be made more background layer 5 as a separate covering film or as the bottom layer of the laminated film 30. In addition, between alloy covering film 32 and the insert 90 may be such additional background layer 5 as a separate covering film or the alloy layer covering the captives and 32 or insert 90. These background layers 5 can be designed in such a way that they are induced by the laser in the image formation in the overlying layer of the impinging laser radiation reflected and/or non-absorb part or in any case do not pass into the underlying layer. Can also be provided that the background layer 5r placed only in a partial region, located above it sensitive to laser radiation layer is formed by laser induced part of the image.

In the embodiment shown in Fig. 33 sensitive to laser radiation material sensitive to laser radiation layer 4 may contain dyes which, by the method described for the above embodiments, under the influence of laser cause bleaching or discoloration, so that laser-induced image in this layer 4 may be implemented as a color image.
