Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • such layers must be relatively thick and in particular formed without gaps.
  • the document WO 2009/056355 discloses a laminate body having the features of the preamble of Ansprüchs. 1
  • the laminate body should be safe against delamination and also simple and therefore inexpensive to produce.
  • 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.
  • At least one of the three laminate layers is a cover laminate layer.
  • 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.
  • 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.
  • 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 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.
  • 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.
  • 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.
  • first color fields and second color fields further color fields can be provided in the laminate body.
  • 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.
  • 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.
  • the laminate body When viewed at this angle, the laminate body would then be transparent or translucent.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 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.
  • 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.
  • 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%.
  • 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.
  • the ink layer areas and the free areas of a color field are formed in a regular arrangement.
  • a flat color layer can be formed, which is preferably opaque.
  • 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.
  • the color layer areas may be color pixels in a screened color field, between which the free areas are located.
  • 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.
  • 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.
  • opacity 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.
  • 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.
  • 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.
  • the respective color fields for this purpose have a size which is smaller than the laminate body surface.
  • 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.
  • 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.
  • the color fields are formed in different color planes with different colorants.
  • different color effects can be achieved.
  • 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.
  • the appearance 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.
  • 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.
  • 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.
  • 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.
  • a window in which there are no color layer areas 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.
  • 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.

  • This laminate layer can then be gathered together with further laminate layers to form a laminate layer stack and laminated to the laminate body.
  • 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.

  • 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.
