The present invention relates to a method of production of the security or valuable document, and the method of manufacturing a protective element. In addition, the present invention relates to protected or valuable document and a protective element made in accordance with the proposed methods.

Protected or valuable documents, for example banknotes, identity cards and other documents, to protect against counterfeiting are often equipped with various protective elements that help to establish the authenticity of documents and at the same time to protect these documents from unauthorized copying. However, due to the tolerance of the accuracy of the register, due to the manufacturing technology, align relative to each other two or more different protective element in such a way that they complemented each other and formed a common structure, as a rule, very difficult.

Thus, the present invention is to eliminate the disadvantages of the means known from the prior art and, in particular, to offer a secure and valuable documents with a high degree of protection against forgery, with an attractive appearance.

To solve this problem, a method for manufacturing a protected or valuable document and a protective element in accordance with an independent system, the AMI formula. Preferred embodiments of the present invention follow from the dependent claims.

In accordance with the first aspect of the present invention relates to a method of production of the security or valuable document, characterized in that it comprises the following stages:

C) produce a multilayer material comprising a paper substrate, a mask layer provided on the paper substrate in the mask region, and a modified laser marking substance provided in the marked area, and marked the area overlaps the masking region, and

L) a multilayer material in the marked region is subjected to laser exposure order and with precise register to create negative signs in the mask layer and the characters with changed color on the unmasked areas of marked area.

Due to the fact that two different sign made with exact register is formed attractive from the point of view of visual perception marking to verify the authenticity of the document with the original design and formed by two different signs on protected or valuable document. In addition, because of the tolerances register inevitable in a separate manufacturing signs, consider what inoe alignment for third parties will be very difficult. Thus, protected or valuable document has a high degree of protection against forgery.

In accordance with the present invention as a masking layer can be used, for example, a metal layer, and the dielectric layers, in particular dielectric layers that change color depending on the angle, or color printed layers. In the case of metal layers, subjecting the multi-layer material for laser exposure, it is possible to provide matting metal and, thus, with precise registration to migrate from areas with changed color to a brushed metal finish. In the case of thin-film elements with the effect of changing color depending on the angle of observation, which usually contain a translucent absorbing layer of chromium, a dielectric separation layer and the aluminum reflective layer, affecting the laser radiation, it is possible to ensure the removal of only a translucent chrome layer, resulting in a negative sign in the background that changes color depending on the angle, formed by the light grey area.

Preferably in step (L) create characters with changed color and negative signs, which complement each other, forming General information. Characters with changed color and negativespace represent for example, complementary items, letters, labels, sequence numbers, a logo or a single graphic object. In order for these elements complement each other to General information and correctly passed its semantic content and look attractive from the point of view of visual perception, signs with changed color and negative signs must be accurately aligned relative to each other. The correct marking, allowing to establish the authenticity of the document and formed two specified characters, the user can determine without auxiliary means and to understand without comments.

Preferably in step B) a paper substrate and a mask layer covering the marking substance, for example, by printing.

For more color transitions before applying to the paper substrate marking substances some of its sections cover the first layer, which allows for laser action to ensure the change color effect marked area. Alternatively or in addition, the first layer may contain one modified laser marking substance that allows the laser effect on the phase L) in areas covered by the first layer, to create characters with changed color, providing RA is ing color effects.

Instead apply the product with specific properties to the paper substrate, it is advisable to stage C) to introduce a marking substance in the volume of the backing paper. For this marking substance, for example, add a paper weight of the molded sheet, put it in the paper substrate when immersed in a bath or a paper substrate impregnated with a marking substance in the sizing press. Obviously, you can use other methods of coating, such as coating substances with specific properties, method of irrigation or promazyvanie.

In accordance with a preferred embodiment of the invention, before the step (L) to expose the multilayer material of the laser exposure, the mask layer at least in the marked area perform excavation in the form of patterns, characters or a code. In this case, when laser radiation is preferably formed of negative signs, the content of which meaning is associated with the information content of the grooves provided in the masking layer. Two of these information objects are related to each other in meaning, if they are correlated with each other or complement each other. For example, the second information object may indicate the first, fully or partially to repeat it or domanated General information.

According to a preferred variant of the invention, the mask layer in step B) is applied to the film layer and together with the specified layer of the film put on the paper substrate. The mask layer is, for example, the reflective layer is embossed and metallized diffraction patterns or reflecting layer thin-film element to effect changes color depending on the angle of view. However, the present invention is not limited to these options, in particular, the masking layer can also be applied directly to the paper substrate without using a layer of film.

In a variant of the invention, according to which the use of the film layer, the layer may also contain one modified laser marking substance, which allows for phase L) on the unmasked areas of the layer of the film simultaneously and with strict adherence to register to create characters with different color effect. The marks with changed color on the unmasked areas of the paper substrate, signs with changed color on the unmasked sections of the film layer and the negative signs in particular create so that they complement each other, forming General information. In all embodiments, the film layer can be covered with a label substance or marking substance can be entered into about JEM film layer.

At stage L) as the source of laser radiation, preferably using a laser emitting in the infrared spectral region, in particular carbon dioxide laser with a wavelength of approximately 10.6 μm or laser yttrium aluminium garnet doped with neodymium (Nd:YAG), with a wavelength of 1,064 μm.

The present invention also proposed protected or valuable document, made in accordance with the proposed method and containing layered material containing at least one paper substrate, a mask layer provided on the paper substrate in the mask region, and a modified laser marking substance provided in the marked area with laser radiation in a mask layer are formed of negative signs, and the unmasked areas marked area - signs with changed color, these signs are made with exact registration.

According to the second aspect of the present invention relates to a method of manufacturing a protective element, characterized in that it comprises the following stages:

C) make the film layer, the mask field contains a mask layer with grooves in the form of patterns, characters or a code, and in the marked region, overlying the masking region, modified by the laser radiation of the brand is ovochnoe substance, and L) layer of the film in the marked region is subjected to laser exposure order and with precise register to create negative signs in the mask layer and the characters with changed color on the unmasked areas of the layer film.

According to this aspect of the invention, the masking layer is also possible to use a metal layer or dielectric layers, such as dielectric layers, which change color depending on the angle of view, or color printed layers.

At stage L) create characters with changed color and negative signs, which complement each other, forming General information. Also preferably create negative signs and/or signs with changed color, the content of which meaning is associated with the information content of the slots made in the mask layer.

In accordance with the proposed method on the phase L), preferably using a laser emitting in the infrared spectral region, in particular carbon dioxide laser with a wavelength of approximately 10.6 μm or laser yttrium aluminium garnet doped with neodymium (Nd:YAG), with a wavelength of 1,064 μm.

In addition, all variants of implementation of the present invention provides the ability to step L) to create rasterized negative signs. As a result, when the imposition of negative is positive characters and characters with changed color, you can get such options, when, for example, the holographic structure of the metallic mask layer remains visible in reflected light even in the area of negative sign.

Also the present invention relates to a protective element made in accordance with the proposed method and containing layer of the film, in which the mask field contains a mask layer with grooves in the form of patterns, characters or a code, and in the marked region, overlying the masking region, which contains modifiable laser marking substance, and by laser action in a mask layer are formed of negative signs, and the unmasked areas of the layer of film - characters with changed color, these signs are made with exact registration.

The protective element preferably is a security thread, the protective tape, protective film, a patch, a sticker or other conversion element intended for application to protected paper, a valuable document and other similar documents. Along with films, described in more detail below, which are applied to secure the paper or value document, in the present invention can be used, in particular, patches or laminated or necesitaban security threads. In the case of laminated protective threads instead of carbon dioxide l the Zera preferably use a YAG laser grenade doped with neodymium (Nd:YAG), with a wavelength of 1,064 μm beam which penetrates through the laminated film.

In all variants of implementation of the present invention as a modified laser marking substances are used, for example, pigments with an effect that change visible color under the influence of laser radiation, in particular thermosetting colored pigments, such as ultramarine blue. It is obvious that instead of these pigments with an effect, you can use a modified laser marking substance not containing pigments.

In all variants of implementation of the present invention at the stage L) signs with changed color to make color changing when observed in normal ambient conditions. However, monitoring at normal ambient conditions implies the observation in the daylight or artificial light, without a special irradiation protected or valuable document. Alternatively or in addition, characters with changed color on the stage L) pose with the color of luminescence occurring during the coverage of the exciting radiation. When observed in normal ambient conditions specified color luminescence can hardly see, he is only a problem when the lighting is protected or valuable document to the appropriate stimulating irradiation is receiving, moreover, as the excitation radiation, typically use ultraviolet radiation. In these embodiments of the invention as a modified laser marking substance use y, in particular, fluorescent pigments. Y substance with a characteristic properties when observed in normal ambient conditions, preferably manifested as transparent and/or colorless substance.

Further additional embodiments of and advantages of the present invention is explained with reference to the accompanying drawings. To facilitate understanding of the drawings, some elements shown not to scale.

Figure 11 shows a cross-section of the film produced in accordance with an additional embodiment of the invention.

The present invention is explained on the example of the banknote. 1 schematically depicts a banknote 10 containing paper substrate 12 and the through hole 14, is covered with a metalized film 16. Use the first layer film 18 16, as a rule, represents a portion of the embossed metallized diffraction patterns or thin-film element to effect changes color depending on the angle of view. However, the present invention is not limited to the above embodiment. In General, the present invention can be used for the manufacture of multilayer materials containing paper substrate with metal layers, dielectric layers or colored printed layer.

To protect 10 banknotes against counterfeiting along the edge of the metallized film 16 is provided by marking 20 consisting of a coloured sign 22 made in the paper substrate 12, and the negative sign 24 formed in the metal layer 18 of the film 16, and these marks 22 and 24 are made with high precision register.

In accordance with this variant of the invention, the marking 20 is formed by a sequence of letters "PL". However, it is clear that this marking can be represented by any sequence of letters or numbers, graphic patterns or codes. As shown in detail in figure 2, in this embodiment of the invention the upper part of the sequence of letters "PL" formed the sign 22 red in the paper substrate. The lower part of the sequence of letters "PL", fits into the specified upper part, formed by the negative sign 24, located in a metal layer 18, and in this embodiment of the invention indicated a negative sign appears in the form of a white paper on the metal substrate background of the film 16.

To ensure accurate alignment of these marks 22 and 24, thereby to form a solid marking 20 without breaks, first, as shown in section with figa, to the paper substrate 12 is applied to the film 16 containing metal layer 18. Then to the paper substrate 12 and the metal layer 18, a significant surface marked region 30 is applied marking layer 32 containing the modified laser marking substance which under the influence of the laser accordingly changes its color, for example, from transparent to red.

After that, the laminated material comprising a paper substrate 12, a metal layer 18 and the marking layer 32, in marked region 30 influence of laser radiation 34 and, accordingly controlling the laser beam, creating a marking 20 of the required form. As the laser light source is used, for example, carbon dioxide laser with a wavelength of 10.6 microns, which allows high speed to apply the desired marking.

On fig.3b shows a section of the banknote along the line III-III shown in figure 2, after the implementation of laser marking. the ri experiments, the inventors unexpectedly discovered, that is, using the same set of parameters of the laser, it is possible to provide a laser-induced color change marking substance contained in the marking layer 32, and thereby create a color marks 22 in the paper substrate, and to provide local removal of the metal layer 18 of the film and the result is to create in the metallized film 16 negative signs 24.

Thus, due to the fact that the characters 22 and 24 are creating on the same stage, using the same laser beam, they are precisely aligned relative to each other. At this point of the present invention is that, although the markings 20 may be caused by manufacturing deviations register in relation to the edge of the metal layer 18 created at the same time marks 22 and 24 do not have deviations register relative to each other. Thus, these characters complement each other, forming a solid marking 20, without gaps and offset.

In the area of the sign 24 laser irradiation does not cause a color effect in the marking layer 32, and leads only to the formation of the negative sign in the metal layer 18. On the basis of current knowledge it can be explained as follows: when removing the metal layer 18 along with the evaporation of the metal is removed modified laser marking substances is a, as schematically shown in fig.3b. Together with metal, obviously, is the removal of other layers, if necessary, provided on the film, for example an embossed layer of UV varnish (not shown), resulting in a region of negative sign 24 appears white color of the paper substrate 12 located under the film.

According to a variant of the invention shown in figure 4, a metal layer 40 film 16 further comprises a notch 42, made in the form of patterns and microball made, for example, a method of leaching, as disclosed in the patent document WO 99/13157. As shown in detail figa, along the edge of the metal layer 40 within each of the rectangular recess 44, made in the metal layer provided metal microvalve "D" (number 46). Obviously, the example shown here illustrates one of the possible variants of the information provided by the grooves 42, this information may be of any type, in particular, it can represent microprinting.

To create marking 20 film 16 containing a structured metal layer 40, 42, is applied to the paper substrate 12. Then the paper substrate 12 and the metal layer 40, 42 in the marked area on large surfaces cover the marking layer, and then laminated material is subjected to laser environmenta is Yu to create located on top of the marks 20, which is considered in this variant is represented as a sequence of letters "PL".

As shown in fig.4b and essentially disclosed in the description of figure 3, the laser radiation on the sites without the metal layer causes a change in the color of the marking substance from transparent to red. Thus, in the paper substrate 12, and the parts of the film 16 without the metal layer is formed, the mark 48 red. Conversely, when the laser impact on the metallized areas is the removal of the marking substance from the metal layer 40, resulting in these areas 50 you can see the white background of the paper substrate 12.

In particular, in areas that are affected by the laser, microbunny 46 form microprinting white without a metal layer on a red background sign 48. In those places where the laser radiation acts on microvalve 46 partially metallized part of microbooks 46, part of microbooks 46 white color without the metal layer, and the mark 48 red color accurately aligned relative to each other. Importantly, although the markings 20 may be caused by manufacturing deviations register in relation to the edge of the metal layer 40 and grooves 42 made in them microbubble 46, simultaneously created characters 48 and 50 do not have register deviations from siteline each other. Thus, they complement each other, forming a solid marking 20 without breaks and offsets.

According to another variant implementation of the present invention, is shown in figure 5, to the paper substrate 12 is applied the first layer 52, which provides additional color transition marking 20. The first layer 52 is a layer of varnish, which is applied before applying metallized film 16 to the paper substrate 12 and which, as a rule, determines the alignment of the paper, the better the adhesion film 16 and/or brighter appearance of the film.

Unexpectedly, it was found that, accordingly selecting the marking substance and the first layer through the first layer to affect the color change of the marking substance. As shown in the top view presented on figa, and on view in section along the line B-B (figa shown fig.5b, width 54 of the first layer 52 is such that it extends beyond the metallized film 16.

When the laser impact marking substance in the area of the first layer 52 changes its color, for example, from clear to orange, so in the paper substrate 12 is formed mark 62 orange. Moreover, the region 56 located outside of the first layer 52, the color marking substance changes from transparent to red and, thus, in the paper the first substrate is formed mark 60 red. Fits colored marks 60, 62, as described above, also fits with negative signs 64, made in the metal layer.

In addition, the first layer 52 may contain a modified laser marking substance, allowing laser radiation to provide at sections 54, covered with the first layer, different color effects.

In accordance with another embodiment of the present invention, marking 20 create multiple color transitions, as shown in figa in the top view and fig.6b in the cut. In this case, the paper substrate 12 to equip the first marking substance 70, modified by the laser radiation, which under the action of laser exhibits a first color transition, for example, from transparent to red. Partially metallized film 18 16 equip a second marking substance 72, modified by the laser radiation, which under the action of laser exhibits a second color transition, for example, from transparent to green.

In this case, influencing the laser beam, creating a marking 20 "PL" with three visually distinct areas. On the sections of the paper substrate 12 with the first marking substance 70 when laser radiation is formed mark 74 red. On the parts of the film 16 without metal coating, equipped with a second, Markarova the first substance 72, when laser radiation is formed mark 76 green, and metallic parts 18 film 16 as a result of exposure laser radiation is generated negative sign 78, through which you can see underneath a white paper substrate 12. Since all three sites create on the same stage, using the same laser beam, they are precisely aligned relative to each other, even though the markings 20 may be deviation of register relative to the edge of the film 16 and the edges of the metal layer 18.

When this first marking substance is applied, for example by printing on a paper substrate 12 or enter it in the scope of the paper substrate 12. The last of these operations can be carried out either in the process of making paper, adding a marking substance in the pulp in forming sheets or later when immersed in the bath, or in the process of impregnation in the sizing press. You can also use other methods of coating, such as coating substances with specific properties, method of irrigation or promazyvanie.

Provided in the film 16 and the second marking material can be applied onto the film layer is, for example, printing. In addition, the marking substance can be added to the deposited layer, for example to a layer of UV varnish layer, located under paragraph what enkoy, or the adhesive layer. Thus, it is possible, in particular, to create layered effects and additional color, In other embodiments, implementation of the present invention the second marking substance is injected in the manufacture of films, for example in the extrusion process. In this case, the pigments, printed or typed in the deposited layers also allow you to create layered effects and more colors.

Additionally, when printing on paper or a layer of UV varnish, you can create printed patterns such as striped raster.

Obviously, instead of, as disclosed in the description of figure 3, to apply the marking substance on the metallic foil, it can be placed under the metal layer. As shown on the form in the section provided on figa, to the paper substrate 12 is applied marking layer 90, which contains pigment, essentially transparent in the visible region of the spectrum and fluorescent in ultraviolet light, and the fluorescent properties of the specified pigment in the laser impact is lost. In the overlap region on the marking layer 90 impose film 16 containing metal layer 18. For multi-layer material is exposed to laser radiation 34, and accordingly controlling the laser beam, creating a marking 20 of the required form.

In the laser exposure is luorescence properties of fluorescent pigment 90 outside the area of overlap is lost, as a result, the marks 22 with changed color fluorescence. On the contrary, in the area of overlap of the laser beam energy is used to evaporate the metal layer 18, and therefore the fluorescent properties of the marking layer 90 in the area of negative 24 characters do not disappear. On fig.7b shows the proposed multi-layer material after laser exposure.

On figs shows an external view of the proposed multi-layer material when observed under normal conditions, i.e. when observed under natural daylight or artificial light. Under these conditions, it is possible to see only the negative signs 24 within the metal layer 18. The local disappearance of the fluorescent properties of the pigment 90 in the area of the sign 22 remains invisible. On figs specified local extinction schematically indicated by the dashed line mark 22.

In the study of the multi-layered material under ultraviolet light, as shown in fig.7d, marking 20 formed by the marks 22 and 24, is shown completely. Fluorescent pigment 90 when excited by ultraviolet light glows characteristic color fluorescence. While outside the overlapping region in the area of 22 characters fluorescence is absent, as in this place the fluorescent properties of the pigment 90 disappeared as a result of laser irradiation. Thus, mn is key 22 on a light background fluorescence appear dark. The metal layer 18 in the ultraviolet light also looks dark, except for the characters 24, with which a metal layer has been removed, but the pigment 90 is not destroyed. As a result, fluorescence can be observed in the region of 24 characters. In addition, in the present embodiment, the present invention simultaneously created the marks 22, 24 also complement each other, forming a solid marking 20, without breaks and offsets, with full markings, unlike the above options, you can see only when considered in ultraviolet light.

Using some pigments can provide additional visual effects. In accordance with a variant of the invention, shown in Fig, on top of the layer with fluorescent pigment 90 and metalized film 16, 18 put a layer with a pigment 92 changes its color under the influence of laser radiation, it changes its color, for example, from transparent to red.

In this embodiment, when the observation of the multi-layered material under normal circumstances, it will look as shown in figa, and in this case, marking 20 is formed by a negative sign 24, made in the metal layer 18, and the sign 22 red color, made in the layer of pigment 92 changes its color.

As shown in fig.8b, when observing the multi-layered material in ultrafi the violet light marking 20, formed by the marks 22 and 24, also can clearly see, however, in this case, its appearance will be different. In the field of marks 22 fluorescence is absent, as in this area along with the color change pigment 92 has been the disappearance of the fluorescent properties of the pigment 90. On the contrary, outside marks 22 and the metal layer 18 can be observed fluorescence, thus, marks 22 on a light background fluorescence appear dark. The metallic coating 18 in ultraviolet light looks dark, except for the 24 characters, which were removed metal layer located on top of the layer with pigment 92 changes its color, and fluorescent pigment 90 was not destroyed, as a result, in these places you can also observe fluorescence.

Figure 9 shows another variant of implementation of the present invention, according to which use two coats of fluorescent pigments, which are located one on top of another. In this case, use two transparent pigment 90, 94, fluorescent in ultraviolet light of different colors, and the energy of the laser beam is chosen so that in the area of the sign 22 disappeared only fluorescent properties of the top layer with pigment 90.

In this case, when observing the multi-layered material under normal conditions of which will look like this, as shown in figa, and its appearance coincides with the appearance of the multilayer material, depicted on figs. As shown in fig.9b, ultraviolet light metal layer 18 looks dark. As in the area of the sign 22 fluorescent properties of the top pigment 90 laser exposure erased, when observed under ultraviolet light reveals itself only color fluorescence intact lower pigment 94. In other areas, i.e. in the area of the mark 24 and the field outside the metal layer 18 and 22 characters, both pigment 90 and 94 is not damaged, so in these areas you can observe the mixed color of two colors of fluorescence.

In particular, the above-described multilayer structure can be used in combination with additional visual effects, disclosed in German patent application DE 10 2008 019 092.6, the description of which is incorporated into the present application. In short, these additional visual effects are made as follows:

B1) is made of a multilayer material formed of at least one paper substrate containing marked in the field to be modified laser marking substance, and also referred to in the marked area of the protective element, which under the influence of laser radiation becomes the becomes thinner, and

L1) influence the multilayer material by laser radiation to at the same time and with strict adherence to register to create in the protective element is a thin line, and in a paper substrate by modifying the marking substance - signs

or

B2) to produce a multilayer material formed of at least one paper substrate containing marked in the field modified by the laser radiation of the first marking substance, and a film element containing the marked area of the second modified laser marking substance, different from the first, and

L2) affect multilayer material by laser radiation in order by modification of the marking substances simultaneously and with strict adherence to register to create marks in the paper substrate and the film element.

In particular, described in this application can also be used in conjunction with visually recognizable characters, disclosed in the publication WO 2006/079489 A1, and the description of the specified well-known solution is incorporated into the present application. In short, in accordance with the technical solution known from WO 2006/079489 A1, visually recognizable signs in the form of patterns, letters, numbers or images are made as follows:

a) made of a multilayer material, containing the second paper substrate, the first section with a relief structure and a second section,

b) on the first section with a relief structure and the second section put the mask layer, and areas containing mask layer, react differently to laser radiation of a selected laser source, and

c) first and second area are subjected to laser radiation of a selected laser source for laser exposure in at least one of the two above-mentioned parts to create negative signs.

In this part of the paper substrate, in which the laser irradiation is formed negative signs may contain modified laser marking substance of the type indicated above. Thus, when the laser impact on the plot masking layer are formed of negative signs, and on a paper substrate, below, are formed characters with changed color, and these marks are created at the same time and with exact registration.

While the first section of the mask layer, in particular, is made in the form of a relief structure with a lattice image specified by the first lattice constant and a first orientation of the lines of the grating, and the second segment is preferably made in the form of a relief structure with a lattice image specified by the second lattice constant and the Torah orientation of the grid lines. The second lattice constant and/or a second orientation different from the first lattice constant and/or the first orientation. Additional features of the possible embodiments of the above-mentioned parts, the features of the process control and the underlying principle of interaction of different intensities are shown in the above publication WO 2006/079489 A1, incorporated into the present application by reference.

In accordance with another variant of the present invention rastrirovano the demetalization allows to obtain the overlap of the negative characters and characters with changed color, in which the holographic structure of the metal layer remains visible. In this case (figa) on multi-layer material 100 containing the paper substrate 12, a marking layer 32 and the metal layer 102 with a holographic structure 104, influence of laser radiation, and accordingly controlling the laser beam, get rasterized character 20, the required form.

In particular, as shown in figa, perform raster in the form of thin strips, but you can choose any other shape. In order to better distinguish between the strips, they are shown on figa in an enlarged scale. In practice, one should choose such a fine raster, so that the band could be seen without optical vspomogatelnymi, but with difficulty.

In the area of the metal layer 102, influencing the laser beam, is formed simultaneously negative signs 24 and congruent color marks 22 in the paper substrate 12. In a paper substrate outside of the metal layer 102 color marks 22 continue without deviation register relatively non-ferrous detalizirovannym marks 22, 24 of the metal layer 102.

How visually looks the specified marking 20 when seen in reflected light and transmitted light, shown respectively at fig.10b and 10c. While choosing such a fine raster that to the naked eye to detect the separation of the markings 20 on the band raster impossible. Thus, as shown in fig.10b, when considering the multi-layered material in the reflected light due to the raster can be seen as the design color of the mark 22, and the hologram 104 of the metal layer 102. On the contrary, as shown in figs, when observed in transmitted light can be recognized only design color sign 22.

According to another variant implementation of the present invention the marking, as shown at 11, to create directly on the foil. For this film 80 in the area of the metallization, metal layer 82 contains recesses in the form of patterns, characters or a code.
