Description

The invention is based on a laminate body formed from at least three laminate layers, wherein the laminate body comprises at least two color fields, which are arranged one above the other, each in at least two mutually parallel, lying in the laminate body inside and spaced apart color planes, each by at least a color layer region and at least one free region are formed, wherein the at least one color layer region is formed by a colorant preparation and there is no colorant preparation in the at least one free region.

A security document consisting of several layers, for example, is in DE 197 31 968 A1 specified. Apart from at least one machine-testable magnetic layer, this document is equipped with a further layer which is partially transparent in the visual spectral region, this further layer being arranged above the magnetic layer so that the magnetic layer is concealed. The partially transparent layer may be formed, for example, by a screened layer, wherein the individual grid elements are made opaque. The raster elements can be produced by means of any printing ink, preferably with a white or light printing ink.

Furthermore, such security and / or value documents are also in DE 10 2008 012 424 A1 described. These documents consist of a polymer layer composite, which is formed from a plurality of substrate layers and in which a personalizing and / or individualizing information is or will be stored by printing technology. These documents are prepared by the following method: providing the polymer layers, printing a personalizing and / or individualizing information on at least one polymer layer, assembling the polymer layers into a layer stack, and laminating to the polymer layer composite. The personalizing and / or individualizing information, for example a multicolored facial image of a person, is first broken down into at least two printing extracts for the printing process, each of which comprises partial information, namely for example in each case a monochrome and / or multicolor printout of the facial image. Then, the print separations are printed on at least two different polymer layer surfaces matched, so that the printed print separations in the polymer layer composite over one another in register and together reproduce the personalizing and / or individualizing information. The polymer layers are collected in such a way that the polymer layer surfaces printed with the pressure separations are internal surfaces in the layer stack. The print separations are preferably generated by means of an inkjet printing process.

For the free design of a value and / or security document, it would be advantageous to cover layers as in DE 197 31 968 A1 provide, with which devices, such as the semiconductor chip and the antenna of an RFID circuit can be hidden within the document. However, this presupposes that the cover layers are sufficiently opaque in the visible spectral range and that they thus sufficiently absorb in the visible spectral range or at least scatter the light. For this purpose, such layers must be relatively thick and in particular formed without gaps.

However, it has been found that such developed documents, at least in the area of these layers, are not sufficiently safe against delamination, since the opaque cover layers counteract a firm, flat bond between the surfaces of adjacent laminate layers. This problem facilitates falsification of a document, since the individual layers can be relatively easily separated. Although a primer can be applied between the cover layer and the laminate layers to increase the peel strength. However, this additional measure does not eliminate the problem of lack of adhesion of the ink layer to a laminate layer.

Efforts have continued to hide internal devices with opaque polymer layers and foil cutouts laid in recesses in the laminate layer. However, problems arise with such a structure, such as unevenness on the outer surfaces of the document, which result from the fact that the cutouts, which are inserted into cut laminate layers, can not be produced with arbitrarily high precision, so that in the region of the recess edges unevenness on the Form the outsides of the document. In the same way, transparent windows in an opaque laminate layer could also be produced by inserting a transparent film cutout into the opaque laminate layer For example, to make a look-through window for an electronic display. In this case too, unevenness would inevitably form on the outsides of the document. Moreover, the insertion of foil cutouts is labor intensive and therefore costly, since the cutouts must be made very precisely and placed in the recesses and it may also be necessary to fix the cutouts prior to stacking the laminate sheets in the laminate sheet having the recesses, in one additional lamination step first a prelamel is produced. If, for the production of windows, only a recess is formed in an opaque laminate layer and no transparent film cutout is inserted, there is also the risk that air bubbles accumulate during lamination within the recess. Finally, it is not possible with these clips to achieve any graphic designs of the document.

The document WO 2009/056355 discloses a laminate body having the features of the preamble of Ansprüchs. 1

It is therefore an object of the present invention to provide a laminated body consisting of a plurality of laminate layers, which has opaque areas and possibly optically transparent windows, for example to conceal an electronic circuit inside the laminate body, but visibly displays a display element of the circuit from outside receive. In addition, the laminate body should be safe against delamination and also simple and therefore inexpensive to produce.

This object is achieved by the laminate body according to claim 1, the method for producing the laminate body according to claim 8 and the use of the laminate body according to claim 9. Preferred embodiments of the invention are specified in the subclaims.

The laminate body according to the invention is formed from at least three laminate layers and comprises at least two color fields, which are arranged one above the other and which each lie in one of at least two color planes. The color planes are parallel to each other, lying inside the laminate body and spaced from each other. Because the color planes are arranged inside the laminate body, manipulation of the color layer areas lying in the color planes is greatly impeded because the color layer areas have to be extracted for manipulation and the laminate body must be delaminated at least in the area of these color layers.

The color fields are furthermore formed by at least one color layer region and at least one free region, the at least one color layer region being formed by a colorant preparation and no colorant preparation being present in the at least one free region. The colorant formulation may be translucent (semi-transparent) or opaque. In principle, the colorant preparation can also be transparent. The ink layer areas are preferably produced in a grid.

In accordance with the invention, there is above and / or below none of the at least one free area of a first color field in a first color plane an open area of a second color field in a second color plane.

1. (a) Bereitstellen der mindestens drei Laminatlagen,
2. (b) Erzeugen von mindestens zwei übereinander angeordneten Farbfeldern in jeweils einer von mindestens zwei zueinander parallelen und voneinander beabstandeten Farbebenen auf Oberflächen mindestens einer der mindestens drei Laminatlagen,
3. (c) Zusammentragen der mindestens drei Laminatlagen zu einem Laminatlagenstapel, sodass die Farbebenen im Laminatlagenstapel innen liegend angeordnet sind, und
4. (d) Verbinden der mindestens drei Laminatlagen durch Laminieren.

The following procedure is used to produce a laminate body formed from at least three laminate layers:

1. (a) providing the at least three laminate layers,
2. (b) generating at least two color fields arranged one above the other in each case one of at least two mutually parallel and spaced-apart color planes on surfaces of at least one of the at least three laminate layers,
3. (c) collating the at least three laminate layers into a laminate ply stack so that the color planes in the laminate ply stack are disposed inside, and
4. (d) bonding the at least three laminate layers by lamination.

Preferably, at least one of the three laminate layers is a cover laminate layer.

In accordance with the invention, the color patches are formed with the formation of color layer areas and open areas, so that above and / or below none of the at least one free area of a first color field in a first color plane is a free area of a second color field in a second color plane. The color patches in the two planes at least overlap. They can also be arranged in register with one another.

The laminate bodies according to the invention are preferably used as value and / or security documents or for the production of valuable and / or security documents, for example identity cards, passports, ID cards, access control cards, visas, tickets, driver's licenses, motor vehicle papers, securities, credit cards , Chip cards, Banknotes and the like. The document can be in the format ID-1, ID-2 or ID-3, and thus, for example, in the form of a map.

By forming the free areas in the color patches, laminate layers which adjoin one another during lamination can readily bond to one another by contacting the materials of the adjacent laminate layers in the free areas, so that an intimate bond is achieved between the materials of the laminate ply to be joined. The ink layer areas enclosed in the laminate material during lamination do not affect the adhesion of the laminate layers to each other.

The disadvantage of the lack of optical opacity due to this measure due to a first such color field having at least one free area is compensated by at least one second such color field in a second color plane. Because, according to the invention, any of the free areas of the second color field are above and / or below none of the free areas of the first color field - i. in a projection of the first free areas perpendicular to the laminate body surfaces on the second color field in the second color plane there are no free areas, and in the same way is in a projection of the second free areas of the second color field perpendicular to the laminate body surfaces on the first color field no there free area -, A sufficient optical opacity is achieved by the colorant preparation, at least as far as the laminate body is considered in the direction of the surface normal of the laminate body. The fact that the two color fields lie in different (spaced apart) color planes, ensures that the adhesive strength is not affected by the color layers.

By dividing the color layer areas on color fields in multiple color planes, it is therefore possible to connect the laminate layers better and more firmly together, so that delamination is excluded or at least made more difficult. According to the invention, the division of the ink layer areas also presupposes that the ink layer areas in one color plane overlap with the open areas in another color plane in order to achieve complete ink coverage. The division of the ink layer areas on multiple color planes can be used as a security feature in a value and / or security document. Because the division may, for a suitable design (type of arrangement of the ink layer areas and free areas within a color field) lead to special optical effects, for example, if at least on the visible side of the laminate body translucent or optionally transparent colorant preparations are used. On the other hand, the division itself is suitable as a security feature in that several color planes and superimposed color fields must be present whose free areas must not overlap.

If the ink layer areas themselves have a sufficient opacity, which is achieved by a sufficiently large pigment concentration in the colorant preparations and thus in the ink layer areas and / or by sufficiently large pigment particles, by means of the ink layer areas, which preferably overlap one another, a complete or at least almost complete Opacity of the color fields are created.

In addition to first color fields and second color fields, further color fields can be provided in the laminate body. For example, in a further preferred embodiment of the invention, it may be provided that the laminate body has at least one third color field with at least one color layer region and at least one free region in a third color plane, wherein the third color field above or below the first and the second color layer region or between the first and the second color coat area. Namely, if the free areas of the first color field and the second color field are about the same as the distance of the color planes from each other, sufficient opacity would be unattainable with regular arrangement of the free areas in their color fields in certain viewing directions relative to the laminate body surface, since the free areas under this viewing angle with each other would be aligned. When viewed at this angle, the laminate body would then be transparent or translucent. By a third color field in a third color plane, which in turn is spaced from the first and second color plane, this transparency or translucency can be prevented, so that there is sufficient opacity through the color fields from all viewing angles. For if the free areas of this third color field are aligned with the free areas of the first and second color fields so that they also block a free view at a suitable viewing angle by aligned free areas in the latter color fields, a complete opacity of the document is achieved in the color fields. By the third color field and in particular when the screening in this color field is finer than that in the first and / or second color field, a greater overlay of the color layer areas is achieved, which gives an impression of higher color coverage.

Of course, the light transmission of the laminate body can be further reduced as more, fourth, fifth, sixth, etc. color patches are introduced into the laminate body in further, fourth, fifth, sixth, etc. color planes. Of course, the prerequisite for creating an increased opacity is always that the color fields are arranged one above the other, i. overlap each other, so that in this overlap region, the desired low light transmission preferably in the visible spectral range and / or optionally in the UV and / or IR spectral range results.

The geometrical conditions for producing an opacity of the color fields (which can be produced in the entire laminate body or only in a part thereof) depend on the light transmittance of the color layer areas, their respective lateral extent, ie extension in the color plane, of the respective lateral extent of the free areas in the color fields and the thickness of the laminate layer between superimposed color planes. It is assumed in each case that a laminate layer, individual laminate layers or all laminate layers of the laminate body and in particular that (s) which is / are located between adjacent color planes, are / are transparent or translucent. The light transmittance of the laminate body is lower when the light transmittance of the ink layer portions is lower. This can be achieved by an increased pigment and / or dye content and / or by larger pigment particles and / or by pigments and / or dyes with higher light absorption in the colorant preparation and / or by a greater thickness of the ink layer areas. In addition, the light transmittance of a color field is reduced by the fact that a larger proportion of a color field is occupied by color layer areas and a smaller proportion by free areas. The angular range around the surface normal of the laminate body, in which a sufficient opacity is obtained, is particularly great if the ink layer areas occupy the largest possible area proportion of the color field and the free areas as small as possible area and if the thickness of a laminate layer between the two color planes as small as possible is. By contrast, if the thickness of this laminate layer is much greater than the lateral extent of the ink layer regions, this angular range is small. However, any reduction in the proportion of free areas in a color plane is not advantageous because the adhesion of the adjacent laminate layers can be reduced if the proportion of free areas is very low. Therefore, the area ratio of the free areas in a color plane is preferably at least 5%, more preferably at least 10%, and most preferably at least 20%. The maximum area proportion of the free areas is preferably 70%, more preferably 55% and most preferably 40%. The area fraction of the free areas is most preferably at least 15% and at most 45%.

In addition, in order to minimize the light transmittance of the laminate body, the aforesaid third, fourth, fifth, etc. color patches may be provided in a third, fourth, fifth, etc. color plane, in particular a transparency / translucency along visual axes at an angle> 0 ° perpendicular to Laminate body surface to block through the free areas of different color fields.

In a further preferred embodiment of the invention, the ink layer areas and the free areas of a color field, preferably at least within a predetermined area element of the color field, are formed in a regular arrangement. With such an arrangement, a flat color layer can be formed, which is preferably opaque. By a regular arrangement is meant a matrix-like arrangement of the ink layer areas and free areas in a color field, i. the color layer areas and free areas are arranged two-dimensionally at regular intervals and in a regular pattern relative to one another. For example, the color layer areas may be color pixels in a screened color field, between which the free areas are located. In this case, for example, the color layer regions may be arranged equidistant from one another in straight and mutually parallel rows, with the color layer regions in a first row with color layer regions in an adjacent second row being in gap or face each other. In the former case, a densest arrangement ("graphite lattice") with 60 ° angle forming connecting lines of adjacent color layer areas and in the latter case an arrangement with 90 ° angle forming connecting lines of adjacent color layer areas in a color plane is formed.

Decisive for the opacity (opacity) of the laminate body in the area of the color fields are also the size of the color layer areas and the size of the free areas in one color plane compared to the size of the color layer areas and the size of the free areas in another color plane. If, for example, the size of the color layer areas and the size of the free areas in color fields of adjacent color planes are each exactly the same and in each case significantly smaller in a third color field, an effective reduction of the light transmission with a preferably opaque colorant preparation over all viewing angles can be effective be achieved. For example, the lateral extent of the color layer areas and the lateral extent of the free areas in color fields in the first and second color planes may be three to four times greater than the lateral extent of the color layer areas in a color field in the third color plane or the lateral extent of the free areas in FIG this third color field. Of course, any combinations of the sizes of the ink layer areas and free areas in color fields of multiple color planes are possible to influence the light transmittance.

In addition to the overlapping color fields which form a design element in a first region of the laminate body, it is of course also possible to provide further color fields in the sense according to the invention in order to design second and further regions of the laminate body in the manner according to the invention. In this case, the respective color fields for this purpose have a size which is smaller than the laminate body surface. In addition, the respective color fields are in this case in different regions of the laminate body and thus not on top of each other, so they do not overlap. Namely, in the sense of the invention, a group of color fields in different color planes forms the effect according to the invention if the color fields of this group are also superimposed, i. at least overlap each other. For example, different groups of color patches in different regions of the laminate body may be used to form an RFID chip having an antenna in a peripheral first region of the laminate body by means of a first group of color patches and also a magnetic bar code in a second region using a second group of color patches to cover up.

In a further preferred embodiment of the invention, the color fields are formed in different color planes with different colorants. Thus, different color effects can be achieved. For example, mixed colors can be produced in this way, which vary at different viewing angles (generation of optically variable hues). Because with two color fields in two color planes in different colors, both colors are visible when viewed vertically, forming a mixed color. When viewed at an angle> 0 ° perpendicular to the surface of the laminate body, the appearance may change because the above color field then optionally at least partially obscures the color field below, so that it dominates the perceived hue. If, in a color field, the color layer areas are also formed with a laterally varying size and / or the open areas with a laterally varying size, they can also merge into one another Shades are generated. Yet another optical effect can be generated if one of the two color fields are formed with different colors merging into one another.

By way of example, the first color layer regions of an overhead first color field can also be formed in a first color plane with a first translucent or transparent colorant preparation and the second color layer regions of a second color field below in a second color plane with a second colorant preparation, which is however opaque. In this case, the second color layer areas in the second color field below are visible through the first translucent or transparent color layer areas lying above, so that in turn a still different optical effect can be achieved, which can also be evaluated as a security feature.

The color layer areas of at least one color field can be formed by color pixels in a screened representation. The color pixels may be fused together or at least partially spaced apart. In the latter case, there is a free space between two color pixels. A color pixel may also be spaced from all adjacent color pixels such that an open area completely surrounds that color pixel. The color pixels may be arranged irregularly or regularly in the manner indicated above.

In a further preferred embodiment of the invention, within a region formed by at least two color fields lying one above the other, there is a window in which there are no color layer areas. The windows in the at least two color fields are preferably one above the other in register. For example, a color field may be formed in each case a color plane surrounding an area in which no color layer areas are located. In this area, the laminate layers on which the color patches are located are not rendered opaque, i. their transparency or translucency is maintained. Such a configuration may serve, for example, to conceal an electrical circuit within the laminate body with the ink layer areas, but to obtain an indication of the electrical circuit visible through the window to the outside.

The color fields are preferably formed on at least one laminate layer of the document, for example applied, preferably printed with printing inks, in particular with an offset printing method. In principle, a gravure printing process can also be used.

In a preferred embodiment of the invention, a laminate layer has a first and a second surface, so that the first color field can be applied to the first surface and the second color field to the second surface of this laminate layer. This laminate layer can then be gathered together with further laminate layers to form a laminate layer stack and laminated to the laminate body. In order for the two color planes to be arranged inside in the laminate body, in each case a further laminate layer is laminated on each surface of the laminate layer in this case. The provided with the color fields laminate layer is placed inside to protect the ink layer areas against tampering.

For example, white ink can be printed as a screened structure in at least two layers by a double-sided offset printing on a laminate layer. In the process, the structures overlap in such a way that a surface appears white to the viewer and also opaque or translucent. By screening the print pattern and distributing it over several layers in the laminate body, the ink coverage required for the desired opacity can be reduced in a single layer, so that a connection of the laminate layers occurs in the color gaps (free areas) during lamination.

In principle, the first and the second color field can also be formed on different laminate layers, wherein the color planes are spaced from each other.

The laminate layers may be formed by a film or paper, or they may contain a film and / or paper material. The laminate layers may be in a sheet format or alternatively in roll form. In principle, materials which are customary in the field of value and / or security documents can be used as materials for the laminate layers. The polymer materials may be identical or different and are based on a polymer material from the group comprising polycarbonate (PC), in particular bisphenol A polycarbonate, polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), thermoplastic polyurethane elastomers (TPU), polyethylene (PE) , Polypropylene (PP), polyimide (PI), poly-trans-isoprene, polyvinyl chloride (PVC), and copolymers of such polymers. The laminate layers may consist of or contain these polymers. Alternatively, the laminate layers may be made of paper, paperboard or fabric or contain these materials. Alternatively, they may consist of a mixture of the aforementioned materials or contain or consist of a composite of individual of these materials. The laminate layers are preferably transparent or translucent. At least in the regions in which the color layer areas are formed, they are transparent or translucent.

To produce the ink layer areas, the printing inks commonly used in printing technology can be used.

Due to the flexibility of the conventional printing methods with regard to the layout, it is possible with the laminate body according to the invention and its production method to introduce opaque, translucent and / or transparent graphic elements into the laminate body which can not be realized by using transparent or translucent film cut-outs in an opaque laminate layer. By dividing a layout in the manner according to the invention onto a plurality of color layer areas in different color planes, the laminate body design can be expanded by a targeted design with transparent, translucent and / or opaque areas. Further, run-off zones may be created from opaque areas to transparent areas. As stated, electronic components in the laminate body can be covered and optionally display elements (for example displays) of these components can be integrated into recesses in the opaque areas. As also stated, optical effects can be achieved with a variation of the viewing angle. Moire effects can also be generated inter alia by combining different colors in halftone printing. A layout of a laminate body can be adapted to changing product requirements.

The inventive construction of the laminate body to form opaque areas in the regions of the color fields can also be used for the graphic design of the laminate body, for example by arranging opaque field regions in a checkerboard pattern. If, for example, outside of an opaque color field region, the free areas in a color plane overlap only partially with the color layer areas in a color plane arranged above or below, so that the free areas in the adjacent color planes partly overlap, further graphic effects can be generated in regions outside the opaque regions formed according to the invention , For example, the degree of overlap of the exposed areas in the adjacent color planes parallel to the color planes may continuously change, resulting in a gradual change in the translucency of the laminate body from one location of the laminate body to another. In addition or in addition The sizes of the color layer areas and / or the free areas in a color plane, in individual color planes or in all color planes can also change, and / or the arrangement of the color layer areas can be varied in one color plane, in individual color planes or in all color planes, for example one regular arrangement to an irregular arrangement. In this way, the most varied graphic designs of the laminate body can be produced in addition to the opaque regions, in which the free areas in one color plane completely overlap with the color layer areas of another color plane.

In the figures, like reference numerals designate elements having the same function.

The in Fig. 1 shown construction of a laminate body, such as a security and / or security document, comprises a plurality of laminate layers, which are laminated to a laminate stack 1 after the collation. In the laminate stack 1, there are the following laminate layers (from below): a stack of a plurality of laminate sheets 5 constituting the lower document part, a core sheet 10, a first transparent sheet 20, a second transparent sheet 30, a third transparent sheet 40 and a transparent one Cover film 50. The films of the laminate layers 5, the core film 10 and the transparent films 20, 30, 40, 50 may in principle consist of any of the conventional materials for the production of value and / or security documents, in particular PC, PVC or TPU. The stack of several laminate layers 5 forms the underside of the laminate stack 1. Its structure, like the upper part, can be formed with the layers 10, 20, 30, 40, 50 in order to make this side also at least partially opaque.

On the two surfaces of the second transparent film 30 are each a pressure field (color field) in the form of raster prints on print layer areas (color layer areas, print pixels) generated, namely a first screen printing 32 and a second screen printing 34. Further, on one of the two surfaces of the first transparent Foil 20 generates a pressure field in the form of a third screen printing 22. These pressure fields 22, 32, 34 are located in different pressure planes (color planes), which are spaced apart from each other. They are arranged one above the other. In the regions of the screen prints 22, 32, 34 are also superimposed surfaces 25, which are not printed and therefore together form a window in the screen prints. Due to the transparency of the films 10, 20, 30, 40, 50, the document is completely transparent in this area, so that, for example, an electronic display, which is located in this area below the area 25, is visible from above.

The first raster print 32 is formed by first print pixels 321 and respective first free areas 322 lying between them. The second screen printing 34 is formed by second printing pixels 341 and in each case lying second free areas 342. The first free areas 322 overlap with the second print pixels 341, and the second free areas 342 overlap with the first print pixels 321. The first and second print pixels 321, 341 and the first and second free areas 322, 342 between the print pixels 321, 341 are compared to the third print pixels 221 and free areas 222 between these print pixels 221 on the surface of the first transparent film 20, relatively large. As a result, a greater superposition of the printing pixels 221, 321, 341 is achieved, so that an impression of a higher color coverage is obtained. When viewing the document from above at any angle to a viewing direction B, the document appears opaque in the region of the ink layer areas 22, 32, 34, except for the window in the area 25. As a result, for example, an electronic circuit located below the pressure fields 22, 32, 34 can be hidden.

When laminating the laminate stack 1, the adjacent laminate layers 10, 20, 30, 40 come into contact with each other via the free areas 222, 322, 342, so that the layers 10, 20, 30, 40 firmly connect to one another in this area.

In Fig. 2 is shown on the basis of the second transparent film 30, as the offset of the print pixels 321, 341 and free areas 322, 342 printed thereon on one another has an effect on the opacity of this film 30 under different viewing directions. In this case, it is first shown that over the free areas 322 in the lower printing plane, in the the print field 32 is formed, no free areas 342 of the upper printing plane, in which the pressure field 34 is formed, are located. That is, the free areas 322 of the lower printing plane completely overlap with the printing pixels 341 of the upper printing plane. In the same way, the free areas 342 of the upper printing plane completely overlap with the printing pixels 321 of the lower printing plane. As a result, the document is opaque, at least in the viewing direction B, perpendicular to the surface of the film 30 (parallel to the surface normal), since respective printing pixels 321, 341 prevent the passage of light through the film 30 in this direction. However, the opacity of the film 30 in the viewing directions A, C at an angle> 0 ° to the surface normal is not opaque, since the free areas 322, 342 are aligned in these directions.

In Fig. 3 For example, another embodiment in the form of cutouts of two print fields 32, 34 printed on the two surfaces of a film 30 is shown. In the upper illustration ( Fig. 3a ) is a section of the pressure field 34 shown and in the middle representation ( Fig. 3b ) a section of the print field 32. The upper print field 34 is formed by a print layer area 341 and free areas 342. The lower pressure field 32 is formed by a print layer area 321 and free areas 322. The printing fields 32, 34 are printed on the two surfaces of the film 30 in such a way that they lie one above the other in registration in the manner shown. As a result, the free areas 322 of the lower pressure field 32 are below the print layer area 341 of the upper pressure field 34, and the free areas 342 of the upper pressure field 34 are above the print layer area 321 of the lower pressure field 32. The resulting view of the film 30 when viewed from above (FIG. or below) is in the lower diagram ( Fig. 3c ): The free areas 322, 342 are each covered by the print layer areas 321, 341, so that an opaque area appears. Moreover, if the upper and lower print layer regions 321, 341 were differently colored, for example, the upper print layer region 341 yellow and the lower print layer region 321 blue, mixed colors would result in the overlap regions because the blue color of the lower print layer region 321 passes through the upper open regions 342 would seem.

2. Laminated body according to claim 1, characterised in that the laminated body comprises a third colour field (22) with at least one colour layer area (221) and at least one free area (222) in a third colour plane.
3. Laminated body according to any one of the preceding claims, characterised in that the colour layer areas (221, 321, 341) in different colour planes are formed with different colorant preparations.
4. Laminated body according to any one of the preceding claims, characterised in that located inside a colour field (22, 32, 34) is a window (25), in which there are no colour layer areas.
5. Laminated body according to any one of the preceding claims, characterised in that the colour layer areas (221, 321, 341) and the free areas (222, 322, 342) of a colour field (22, 32, 34) are arranged in regular fashion.
6. Laminated body according to any one of the preceding claims, characterised in that a laminate layer (30) comprises a first and second surface, and that a first colour field (32) is formed on the first surface, and a second colour field (34) on the second surface of the same laminate layer (30).
7. Laminated body according to any one of the preceding claims, characterised in that the colour fields (22, 32, 34) are formed by offset printing.
8. Method for the production of a laminated body according to any one of claims 1 to 7, which is formed from at least three laminate layers (5, 10, 20, 30, 40, 50), comprising:

   (a) preparation of the at least three laminate layers (5, 10, 20, 30, 40, 50),

   (b) production of at least two colour fields (32, 34), arranged above one another, in each case in one of at least two colour planes, parallel to one another and spaced apart from one another, on surfaces on at least one of the at least three laminate layers (5, 10, 20, 30, 40, 50),

   (c) assembling the at least three laminate layers (5, 10, 20, 30, 40, 50) to form one laminate layer stack (1), such that the colour planes in the laminate layer stack (1) are arranged lying inwards, and

   (d) connecting the at least three laminate layers (5, 10, 20, 30, 40, 50) by
   laminating,
   characterised in that the colour fields (32, 34) are produced with the formation of colour layer areas (321, 341) and free areas (322, 342), such that a free area (342) of a second colour field (34) in a second colour plane is found above and/or below none of the at least one free area (322) of a first colour field (32) in a first colour plane.
9. Use of the laminated body according to any one of claims 1 to 7 as a value and/or security document or for the production of a value and/or security document.
