Description

Process for producing a polymer layer composite and polymer layer composite with colored security feature

The invention relates to a method for producing a polymer layer composite from a plurality of substrate layers, in which at least one first, preferably personalizing and / or individualizing, information is stored by printing technology, as well as such a polymer layer composite. Likewise, the invention relates to a use of such a method or a polymer layer composite in the production of a security and / or value document and / or a use of such a polymer layer composite as a security and / or value document.

Prior art and background of the invention

Modern security and / or value documents are or are formed as a polymer layer composite or produced from such or include such. Security and / or value documents generally comprise personalizing and / or individualizing information that enables an assignment of the security and / or value document to a person and / or a group of persons, objects and / or entities.

An individualizing information may include, for example, a serial number or an indication of the issuing authority. The personalizing and / or individualizing information furthermore represents a security feature. A security feature is a feature of a security and / or value document which is intended to prevent or at least to make it difficult to copy and / or forge and / or imitate the security and / or security document ,

Personalizing information is considered to be information that includes information that can be assigned to a person. This may include, for example, image information such as a passport photograph, a fingerprint, etc., or alphanumeric strings such as a name, an address, a place of residence, a date of birth, and so forth. As security and / or value documents may be mentioned only as an example: identity cards, passports, ID cards, access control cards, visas, tax stamps, tickets, driver's licenses, motor vehicle papers, bank cards, credit cards, banknotes, checks, postage stamps, credit cards, any smart cards and adhesive labels (eg for product protection).

From the prior art, different methods for the production of value and / or security documents are known. For example, US Pat. Nos. 6,022,429, 6,264,296, 6,685,312, 6,932,527, 6,979,141 and 7,037,013 describe such processes in which inkjet printing is applied to finished blanks which are coated with a protective lacquer or a protective film as protection against mechanical and / or chemical damage and manipulation should be protected. With this method, personalizing and / or individualizing information can be stored in color in the security and / or value document by printing technology. However, the resulting security and / or value documents have only a relatively small security against manipulation, because the printed information is completely printed relatively near the surface and the protective layer of paint or a protective film usually no monolithic, cohesive connection with the card blank forms and thus removable and / or removable. Subsequent manipulation of the printed matter is possible.

The documents US Pat. No. 7,005,003 B2, EP 0 131 145 B1, US Pat. No. 5,734,800 and US Pat. No. 6,765,693 B1 describe methods for printing colored images with different color separations.

From EP 1 322 480 B1 a recording medium, in particular a credit or identity card, with an upper layer and further layers is known, wherein the upper layer has on its outer side a plurality of lenticular lenses and on the back a display element which, upon tilting of the recording medium to At least one axis appears to be movable and wherein the lenticular lenses extend over only a portion of the entire outer side and the display element is a security element which is printed on an inner card layer. The upper layer with the lenticular lenses arranged thereon and the remaining layers of the recording medium are made of polycarbonate. As security element a security guilloche is described. Also known from WO 01/29764 A1 is a card-shaped data carrier with authenticity elements in the interior, which consists of at least one cover film and an optical read-out system arranged at the top through which the authenticity elements arranged in the interior can be read out from at least two different viewing directions with different information content are, wherein the optical readout system consists of a lens structure of Fresnel lenses. As a production method, it is stated that initially in a first method step the authenticity elements are inscribed in the card body through the cover film and in a second method step the microstructure necessary for reading different viewing directions is applied to or in the cover film.

From WO 02/11063 A2 an optically active structure for personalization of cards and the like and a method for their production is known. An optically effective microstructure is proposed for a data carrier of any type in which irreversible changes (information) are inscribed in at least one of a plurality of superimposed films of the data carrier by means of a laser beam, and the information has different information content from different viewing angles on the data carrier ( Tilting or wobbly image). The microstructure consists of mutually parallel, contiguous, approximately strip-shaped regions, both of which are transparent, wherein one region carries a diffractive structure and the other region is diffraction-free and the information to be read is arranged in regions below the microstructure.

Technical problem of the invention

The invention is based on the technical problem of providing a method for producing a polymer layer composite as well as a polymer layer composite in which at least one first information is or will be stored by printing technology which is part of a security feature which has a viewing-angle-dependent color effect, such that the first information against manipulation and / or adulteration and / or such a polymer composite are better protected against imitation than in the known from the prior art polymer layer composite systems, and thus in particular as value and / or security document or as part of a value and / or security document or as part of a manufacturing process of such a value and / or security document.

Broad features of the invention and preferred embodiments

To solve the problem, a method for producing a polymer layer composite from a plurality of substrate layers, in which at least one first information is stored by printing technology, has been proposed, which comprises the steps of providing a plurality of polymer layers as the substrate layers, printing the first information on at least one substrate layer, gathering the substrate layers to form a substrate layer stack and laminating the substrate layers to a polymer layer composite, it being provided according to the invention that the first information is decomposed into at least two pressure extracts, each comprising a partial information of the first information and the printing of the first information in which the at least two Druckauszüge be printed on at least two different substrate layer surfaces matched, so that the printed pressure separations in the polymer layer composite are exactly one above the other and together the first e reproduce information at a viewing angle and at least one color change of the reproduced first information occurs under at least one second viewing angle. The invention thus provides a polymer layer composite which is produced by lamination of a plurality of substrate layers and in which at least one first information is stored by printing technology, wherein the substrate layers are polymer layers and wherein the first information is decomposed into at least two pressure separations, each comprising a partial information of the first information and the at least two printing separations are printed in at least two spaced-apart planes or the at least two printed printing separations are arranged in at least two spaced-apart planes such that the printed printing separations in the polymer layer composite lie one above the other in register and collectively the first information at a viewing angle reproduce and at least a color change of the reproduced first information occurs under at least a second viewing angle. The resulting polymer layer composite thus comprises, incorporated in a composite body, first information stored in at least two spaced apart planes so as to collectively represent the first information at a viewing angle. Under at least a second, different viewing angle results in at least one color change. This means that a spectral distribution of the observable light is different for the two different viewing angles. However, it may also be a change in the reproduced first information set. For example, part of the first information may be obscured and, for this purpose, a second information item that is stored in substrate layers or substrate layer surfaces lying underneath in the document body. Compared to the application of a first information in the interior of a polymer layer composite according to the prior art, an increased protection against counterfeiting is achieved here, since information components must be manipulated at least in two levels. Further, a security feature is created by printing technology, which is easy to verify, but is not duplicated by a copy operation. In particular, first information comprising a high-resolution pattern or image is difficult to imitate because of high precision in aligning the print separations with each other to correctly reproduce the first information. Preferably, the first information is personalizing and / or individualizing information. The created security feature can thus be used to store personalizing and / or individualizing information in the polymer layer composite in such a way that it is easily possible to verify the authenticity of the information about the resulting color change under the at least two different viewing angles.

The first information is multicolored, preferably colorful. This means that the first piece of information can not be reproduced with a single ink. As multicolored information is considered if it causes at least two color impressions in a viewer, with differences in brightness here should not represent different color impressions. As colored information is considered, which causes more than three different color impressions, of which preferably at least one color impression caused by additive color mixing (in luminescent colors) or subtractive color mixing (in so-called body colors) of primary colors that span a color space, or caused can be. Most preferably, the first information comprises a colorful or multi-colored personalizing facial image of a person.

In one embodiment, it is provided that a printed image embodied by the first information is decomposed into pixels and each pixel exactly one of at least two indentations is assigned. The assignment is thus made so that each pixel is assigned to exactly one printout. In embodiments in which more than the at least two pressure separations are used, this means that each pixel is assigned to exactly one of the several print separations. In the arrangement of the pressure separations on top of one another in a substrate layer stack to which the substrate layers are brought together before joining to the document body, there is thus no further layer of the substrate layer arranged along a direction of layering (or opposite to the direction of layering) above a pixel applied on a substrate layer Substrate layer surfaces arranged a pixel or a component of the pixel of the first information. A pixel in the sense used herein has exactly one color that matches an ink or ink. Furthermore, each pixel is assigned a position in a generated two-dimensional print image of the first information.

In another embodiment, it may be provided that individual or all of the print separations are printed multiple times but with register accuracy on different substrate layer surfaces, preferably spaced apart in the composite body, in order, for example, to obtain a better opacity.

It is likewise provided in one embodiment to assign the pixels in each case to several print separations during disassembly, but in such a way that only the same pixel is arranged in different planes in the composite body. A pixel here has only one ink in all printouts.

In one embodiment it is provided that the print separations are hierarchically sorted with respect to their spacing in the polymer layer composite from an upper viewing side (front), with a lowest hierarchical level assigned to the print separation furthest from the viewing side and the print separations modified by pixels of the print separations to which no pixel is assigned, but the corresponding pixel is assigned to a print separation of a higher hierarchical level, a pixel is assigned to a second information. The print separations are thus assigned at those points pixels of the second information, which by a pixel of the first information on an overlying substrate layer surface of the substrate layer stack or one above lying plane of the composite are concealed in a vertical plan view. This offers the advantage, in embodiments using more than two print separations printed on at least three different spaced substrate layer surfaces, that at lower levels, ie, hierarchically lower levels, a number of the printed pixels of the first information are printed pixels of a print separation a hierarchically higher level in a viewing, which deviates from a vertical plan view, are hidden or whose occlusion opaque or opaque fails, increases.

The second information can be formed here as desired. In one embodiment, the pixels of the second information all have a uniform color. These pixels of the second information are or will be printed in white or black opaque or blanket.

In other embodiments, the second information may be colored and derived from the first information or completely independent. For example, it is provided in one embodiment that the second information is derived as a function of the pixels of the first information in the individual pressure excerpts. If a pixel of a print separation, which is covered in plan view by a pixel of the first information arranged above it, has an adjacent pixel which represents a pixel of the first information, then one color can be assigned to the first information depending on the color of the neighboring pixel be so that the most pronounced color effect in a tilting of the substrate layer composite, d. H. when changing the viewing direction, occurs.

Particularly reliable color change effects can be achieved if, at least with respect to a selected direction, preferably with respect to two mutually orthogonal directions, adjacent pixels are respectively assigned to different print separations. Immediately adjacent pixels along the excellent direction are thus always associated with different pressure separations. Preferably, along a second direction orthogonal to the excellent direction, there are also no immediately adjacent pixels of the first information assigned to the same print separation. The pixels will be for example, alternately along the excellent direction associated with the two pressure extracts.

An additional effect to be exploited as a further security feature is realized with an embodiment in which on a substrate layer surface or in one of the substrate layers, at least in the area in which the first information is represented, luminescent means are introduced in such a way that when UV excitation takes place White light is emitted and the substrate layer surface or substrate layer below at least one, preferably all, which is arranged at least two printing extracts in the document body produced. UV radiation stimulates white fluorescence. This includes light of different wavelengths, which causes a white color impression via a color addition. The light is now filtered in through the pixels of the above arranged or printed print separations, so that again the first information can be seen in color at a viewing angle, preferably in a vertical plan view. If the security document is tilted, at least the pixels of the first information printed in adjacent different planes overlap along a line of sight or a light propagation direction of the fluorescent light to an eye of a viewer or a detection device. There is a double filtering, which usually causes a change in hue or at least a change in the brightness of a hue. In addition, you can look at pixels of the second information under pixels of the first information. This also leads, if the second information is present, to a change in information perception.

An independently inventive embodiment of a polymer layer composite with a viewing angle-dependent security feature is obtained by printing the first information, which is preferably individualizing and / or personalizing, onto a substrate layer surface and onto a substrate layer surface underlying it in the polymer layer composite or below it Substrate layer on or introduces luminescent agent. A multi-layer printing of the first information is not required.

In some embodiments, it is advantageous if the printed pixels of at least one of the at least two print separations are partially transparent or translucent in at least one wavelength range. This can be achieved by one prints at least one of the at least two printing extracts with a translucent or partially transparent ink or ink. An ink is translucent or semi-transparent when it is translucent or partially transparent in the printed state in the finished document body.

Furthermore, it is possible to use a luminescence instead of a white luminescence, which radiates in one color. This would be completely absorbed by some colors, but transmitted by others, so that it can produce a viewing angle-dependent luminescence. It is also possible to use different luminescent colors and place them next to, above, or with each other in order to combine the effects with one another. On top of each other, this means a vertical distance in different substrate layers, together a true mixture, which can give a white luminescence, or occupy another part of the spectrum. The emission of wavelengths outside the visible spectral range is explicitly included.

Furthermore, it is possible to print at least one of the at least two print separations with fluorescent inks or inks which emit light in the visible wavelength range only after excitation with UV light. As a result, a viewing-angle-dependent "hidden" first information can be introduced into the security document in a simple manner.

In order to increase counterfeiting and / or manipulation security, in one embodiment the substrate layers are gathered in such a way that the substrate layer surfaces printed with the at least two pressure separations are internal surfaces in the substrate layer stack.

In a preferred embodiment, the at least two print separations comprise a monochrome color separation of an n-color color system, in particular a three-color color system, or an n-color black color system, in particular a three-color black color system. In this case, all known n-color color systems are available, with which colorful or multicolor information can be displayed, wherein the colorful information includes more color values than printing inks are used for the production. With a three-color color system, for example with the colors Yellow, magenta, cyan, can create much of the human perceptible color space by exploiting the color subtraction in human perception of colors. However, it is also possible to use color systems which use more than three colors or more than three colors and black, for example six colors plus black.

In one embodiment of the invention, the at least two print separations comprise monochrome color separations which are each printed on different substrate layer surfaces, m being an integer which will generally coincide with a number n indicating the number of colors of the color system used. However, it is also conceivable that the first personalizing and / or individualizing information is decomposed into a larger number of monochrome print separations, so that exist for single or all colors of the color system two monochrome print extracts, each of which a partial information of the first personalizing and / or individualizing Information include. Of course, these multiple monochrome print separations for one color may include different partial information of the first personalizing and / or individualizing information.

A register-accurate alignment of the at least two pressure separations is particularly easy to implement in an embodiment in which two or at least two printing extracts are printed in register on opposite surfaces of the same substrate layer, the printed print extracts are mirror images of each other when viewing the surfaces. This means that the one print separation which is printed on an upper side of the substrate layer which faces the upper side in the substrate stack, from which the individualizing and / or personalizing first information is to be perceptible, is not imprinted in a mirrored manner. On an underside of the same substrate layer, the print separation is then printed mirror-inverted, if you look at the substrate layer now from the bottom. Viewed from the top side, the at least two pressure extracts complement each other correctly with the personalizing and / or individualizing first information.

In order to be able to correctly perceive the first personalizing and / or individualizing information, it is understood that the substrate layers which are between the individual pressure extensions and are arranged above, transparent or, if they are not transparent, at least translucent. Preferably, all of these substrate layers are transparent.

If the substrate layer or at least one of the substrate layers is printed between the at least two substrate layer surfaces onto which the at least two printing extracts, each comprising partial information of the first, preferably individualizing and / or personalizing, information, are translucent, it is particularly preferred the entire polymer layer composite, at least in the area in which the first, preferably individualizing and / or personalizing, information is stored, translucent, d. H. not opaque, is. In this way, it is possible to generate a transparent, preferably personalized and / or individualized transparency that represents the total information when viewed in backlight. It is thus provided in one embodiment that the polymer layers are all, at least in a region in which one of the substrate layer surfaces is printed with one of the printing extracts, or at least in a region in which one of the in the polymer layer composite above or below arranged substrate layers with a the print separations is printed or is provided, transparent and / or translucent polymer layers, wherein at least one, preferably exactly one, polymer layer, which is arranged between two of the at least two pressure separations is provided as a translucent polymer layer. The remaining polymer layers are preferably all transparent.

In another embodiment, it is provided that at least two of the at least two printing separations are printed on substrate layer surfaces of different substrate layers.

For example, to avoid mirroring one or more print separations, as is necessary when printing subpages of the superimposed substrate layers, it is preferred in one embodiment that all of the at least two print separations be printed on substrate layer surfaces of different substrates.

In order to ensure that the different printed pressure separations are also arranged in the produced polymer layer composite in different planes is at According to one embodiment of the invention, the plurality of substrate layers are brought together so that the substrate layer surfaces which are printed with one of the at least two pressure separations do not adjoin one another directly in the substrate stack.

If the at least two printing separations are not printed on different substrate layer surfaces of one and the same substrate layer, the substrate layers are preferably aligned with one another during collation so that the at least two printing separations are arranged in register in the substrate layer stack one above the other. This presupposes that the substrate layers are essentially formed from the same polymer or at least have the same expansion and / or shrinkage properties when the individual substrate layers are bonded together during lamination.

In principle, all materials customary in the field of security and / or value documents can be used as materials for the polymer layers. The polymer layers can, identically or differently, be based on a polymer material from the group comprising PC (polycarbonate, in particular bisphenol A polycarbonate), PET (polyethylene glycol terephthalate), PMMA (polymethyl methacrylate), TPU (thermoplastic polyurethane elastomers), PE (polyethylene), PP ( Polypropylene), PI (polyimide or poly-trans-isoprene), ABS (acrylonitrile-butadiene-styrene), PVC (polyvinyl chloride) and copolymers of such polymers. Preference is given to the use of PC materials, wherein, for example, but by no means necessarily, so-called low-T _g materials are used, in particular for the polymer layers on which the print separations are printed, and / or for the polymer layers, which with the or the polymer layers that are printed on the side with the inkjet printing. Low-T _g materials are polymers whose glass transition temperature is below 140 ^° C.

The polymer layers can be filled or unfilled. The filled polymer layers contain in particular colorants, which can be both dyes and color pigments, or other fillers. The polymer layers can also be dyed or colorless by means of dyes and in the latter case transparent or translucent. It is preferred if the base polymer of at least one of the polymer layers to be joined contains identical or different mutually reactive groups, wherein react at a laminating temperature of less than 200 ° C reactive groups of a first polymer layer with each other and / or with reactive groups of a second polymer layer. As a result, the lamination temperature can be lowered without jeopardizing the intimate bond of the laminated layers. In the case of various polymer layers having reactive groups, this is due to the fact that the various polymer layers can no longer be readily delaminated due to the reaction of the respective reactive groups with one another and the formation of covalent chemical bonds. Because there is a reactive coupling between the polymer layers, as it were a reactive lamination. Furthermore, because of the lower laminating temperature, it is possible to prevent a change in the colored printing ink, in particular a color change. It is preferred in this case if the glass transition temperature T _{9 of} the at least one polymer layer before thermal lamination is less than 140 ^° C. (or less than 120 ^° C. or less than 100 ^° C.), the glass transition temperature of this polymer layer after thermal lamination Reaction of reactive groups of the base polymer of the polymer layer with each other by at least 5 ° C, preferably at least 20 ⁰ C, higher than the glass transition temperature before the thermal lamination. In this case, not only is a reactive coupling of the layers to be laminated together carried out, but rather an increase in the molecular weight and thus in the glass transition temperature takes place by crosslinking of the polymer within the layer and between the layers. This complicates delamination, splitting, in addition, especially since in a manipulation attempt the high delamination temperatures necessary, for example, irreversibly damage the colors and thus destroy the document. The lamination temperature when using such polymer materials is preferably less than 180 ^° C., more preferably less than 150 ^° C. The selection of suitable reactive groups is possible without difficulty for a person skilled in the art of polymer chemistry. Exemplary reactive groups are selected from the group consisting of -CN, -OCN, -NCO, -NC, -SH, -S _x, -Tos, -SCN, - NCS, -H, epoxy (-CHOCH _2), -NH ₂ , -NN ⁺ , -NN-R, -OH, -COOH, -CHO, -COOR, -HaI (-F, - Cl ₁ -Br, -I), -Me-HaI (Me = at least divalent metal, for example Mg), -Si (OR) ₃ , -SiHaI ₃ , -CH = CH ₂ , and -COR, where R can be any reactive or non-reactive group, for example -H, -HaI, Ci-C ₂ o- Alkyl, C ₃ -C ₂₀ aryl, C ₄ -C ₂₀ -ArAlkyl, each branched or linear, saturated or unsaturated, optionally substituted, or corresponding heterocycles having one or more identical or different Heteroatoms N, O, or S. Other reactive groups are of course possible. These include the reaction partners of the Diels-Alder reaction or a metathesis. The reactive groups may be attached directly to the base polymer or linked to the base polymer via a spacer group. Suitable spacer groups are all spacer groups known to the person skilled in the art of polymer chemistry. The spacer groups may also be oligomers or polymers which impart elasticity, whereby a risk of breakage of the security and / or value document is reduced. Such elasticity-promoting spacer groups are known to the person skilled in the art and therefore need not be further described here. By way of example only, spacer groups may be mentioned which are selected from the group comprising - (CH ₂ ) _n -, - (CH ₂ -CH ₂ -O) _n -, - (SiR ₂ -O) _n -, - (C ₆ HU) _n -. - (C ₆ H ₁₀ ) "-, C ₁ -C _n -AIk ^, C ₃ -C ₍ " _{* 3} rAryl, C ₄ - (W ArAlkyl, each branched or linear, saturated or unsaturated, optionally substituted, or corresponding Heterocycles having one or more identical or different heteroatoms O, N or S, where n = 1 to 20, preferably 1 to 10. With regard to further reactive groups or possibilities of modification, reference is made to the reference "Ullmann ^'s Encyclopaedia of Industrial Chemistry" The term "base polymer" as used herein refers to a polymer structure which does not bear reactive groups under the lamination conditions used, and which may be homopolymers or copolymers modified polymers.

It is advantageous if at least partially polycarbonate (PC) layers are provided as polymer layers, preferably only PC layers. Polymer layer composite systems that include personalizing and / or individualizing information, particularly monolithic polymer layer composite systems made from polymer layers of a plastic material (a polymer), can be used very well as security and / or value documents. A preferred embodiment therefore provides that the polymer layer composite is formed as a security document or document of value.

In one embodiment, it is therefore provided that further relevant known security elements and / or security features are applied to and / or in the substrate layers and / or introduced. Of course, security elements and / or security features also between the substrate layers in the substrate layer stack before lamination. Likewise, application or introduction into the finished laminated polymer layer composite, for example by laser engraving, etc., is possible.

Furthermore, it is possible that in addition to the polymer layer stack before laminating one or more non-polymeric materials, in particular paper, existing further substrate layers are inserted, which is such or such that they are no longer non-destructive of laminating after adjacent substrate layers and / or other adjacent substrate layers can or can be solved. In order to be able to embedding paper layers in a polymer layer composite in the manner indicated, it is advantageous, for example, to provide the further paper-based substrate layer with openings and / or recesses, through which interconnected polymer substrate layers pass through one another during lamination to the paper substrate-based further substrate layer can train.

As further security elements and / or security features, examples include introduced diffractive structures, holograms, embossings, provision of special printing elements such as guilloches or iris printing, etc., use of certain colors, introduction of laser engravings, etc. It will be apparent to those skilled in the art that all security features known in the art can be additionally utilized.

As a further security element, one or more electronic circuits and / or a microchip can be introduced into the polymer layer composite. The electronic circuit may in this case be a discrete component such as an inductor, a capacitor, an electrical resistor, a diode, a transistor, a memory element, a display element or a combination of a plurality of these components comprising an oscillator, an amplifier , a microcontroller or a display. A structure as an integrated circuit proves to be advantageous. These electronic circuits and / or microchips are often designed so that they can be read out and / or described without contact. In order to prevent and / or protect a replacement or manipulation of one of the electronic circuits and / or the microchip, one embodiment provides one or more electronic circuits and / or a first surface of a substrate layer designated as an inlay layer or one or more recesses of the inlay layer apply or apply a microchip and then print one of the at least two print separations on this first surface. Each replacement and / or removal of the microchip and / or the one or more electronic circuits causes in such a case also a change in the first personalizing and / or individualizing information and thus is easy to perceive for a viewer.

Another embodiment provides that a transparent or translucent diffractive security element is at least partially printed directly when printing one of the printing extracts. A further development provides that the diffractive security element, for example a hologram, is applied to a substrate layer which is already printed with one of the printing extracts and is then at least partially directly overprinted with another of the printing extracts. Furthermore, it is of course possible to apply the diffractive element prior to the first printing step on a substrate layer, and to print this subsequently. Furthermore, it can be applied to an already existing pressure separation and then brought into contact with a printing of a substrate layer surface arranged above it, so that the diffractive element is covered on both sides by pressure separations, i. is introduced adjacent to these printed print separations in the polymer layer composite. The introduction of a diffractive element can thus take place before and / or after and / or between the printing of one or more of the substrate layer surfaces. The diffractive security element is thus optimally protected against being exchanged as part of a manipulation of a security document.

In addition to a verification of the viewing direction-dependent security feature by viewing from different viewing directions, a verification can be carried out with tools. A separate lens or a lenticular grid can be easily applied as a verification instrument. By slightly shifting this lenticular raster deeper planes are visible. By tilting the document can be produced with appropriate screening of the printed information different color impressions or -Verschiebungen.

The application of the first personalized information may be in single use or in multiple use, especially in dual use, on rolls provided Polymer layers or provided on sheets polymer layers. Alignment of the individual substrate layers can be monitored by optical control techniques. Similarly, a use of mechanical investment marks, in particular in a collation of the substrate layers in the form of substrate sheets, can be used.

In one embodiment of the invention it is provided that a plurality of first information is printed on the plurality of substrate layers and a plurality of security and / or value documents are divided out of the polymer composite, preferably by being cut out or punched out.

A printing of the substrate layer surfaces with the various pressure separations by means of digital printing processes. In particular, the at least two print separations are printed by means of a transfer printing process or a sublimation printing process or a diffusion transfer process or a transfer process, or more preferably an ink jet printing process (inkjet printing process) and / or a combination thereof.

For the ink-jet printing, in particular on polycarbonate substrate layers, in principle all customary inks can be used. Preference is given to the use of a preparation comprising: A) 0.1 to 20 wt .-% of a binder with a polycarbonate derivative, B) 30 to 99.9 wt .-% of a preferably organic solvent or solvent mixture, C) 0 to 10 wt D) 0 to 10% by weight of a functional material or a mixture of functional materials, E) 0 to 30% by weight of additives and / or auxiliaries , or a mixture of such substances, wherein the sum of the components A) to E) always yields 100 wt .-%, as an ink jet ink. Such polycarbonate derivatives are highly compatible with polycarbonate materials, in particular with polycarbonates based on bisphenol A, such as, for example, Makrofol® films. In addition, the polycarbonate derivative used is stable to high temperatures and shows no discoloration at lamination typical temperatures up to 200 ° C and more, whereby the use of the above-described low-T _g materials is not necessary. In particular, the polycarbonate derivative may contain functional carbonate structural units of the formula (I)

The X atoms alpha to the diphenyl-substituted C atom (C1) may not be dialkyl-substituted. The X atoms beta to C1 may be disubstituted with alkyl. Preferably, m = 4 or 5. The polycarbonate derivative can be prepared, for example, on the basis of monomers, such as 4,4 ^' - (3,3,5-trimethylcyclohexane-1,1-diyl) diphenol, 4,4 ^' - (3,3-) dimethylcyclohexane-1, 1-diyl) diphenol, or 4,4 ^' - (2,4,4-trimethylcyclopentane-1, 1-diyl) diphenol. Such a polycarbonate derivative can be prepared, for example, according to the document DE 38 32 396.6 from diphenols of the formula (Ia), the disclosure of which is hereby incorporated in full in the disclosure of this description. It is possible to use both a diphenol of the formula (Ia) to form homopolycarbonates and a plurality of diphenols of the formula (Ia) to form copolycarbonates (meaning of radicals, groups and parameters, as in formula I).

(Ia)

In addition, the diphenols of the formula (Ia) may also be mixed with other diphenols, for example with those of the formula (Ib)

These and other suitable diphenols are described, for example, in the publications US Pat. No. 3,028,365, 2,999,835, 3,148,172, 3,275,601, 2,991, 273, 3,271, 367, 3,062,781, 2,970,131 and 2,999,846, in the publications DE-A 1 570 703, 2 063 050, 2 063 052, 2 211 956, FR-A-1 561 518 and in the monograph "H. Schnell, Chemistry and Physics of Polycarbonates, Interscience Publishers, New York 1964", which are hereby incorporated by reference in their entireties in the disclosure of the present application , Preferred other diphenols are, for example: 4,4'-dihydroxydiphenyl, 2,2-bis (4-hydroxyphenyl) propane, 2,4-bis (4-hydroxyphenyl) -2-methylbutane, 1, 1-bis ( 4-hydroxyphenyl) cyclohexane, alpha, alpha -bis (4-hydroxyphenyl) -p-diisopropylbenzene, 2,2-bis (3-methyl-4-) hydroxyphenyl) -propane, 2,2-bis- (3-chloro-4-hydroxyphenyl) -propane, bis (3,5-dimethyl-4-hydroxyphenyl) -methane, 2,2-bis- (3,5- dimethyl-4-hydroxyphenyl) -propane, bis (3,5-dimethyl-4-hydroxyphenyl) sulfone, 2,4-bis (3,5-dimethyl-4-hydroxyphenyl) -2-methylbutane, 1,1 Bis (3,5-dimethyl-4-hydroxyphenyl) cyclohexane, alpha, alpha-bis (3,5-dimethyl-4-hydroxyphenyl) -p-diisopropylbenzene, 2,2-bis (3,5- dichloro-4-hydroxyphenyl) -propane and 2,2-bis (3,5-dibromo-4-hydroxyphenyl) -propane. Particularly preferred diphenols of the formula (Ib) are, for example: 2,2-bis (4-hydroxyphenyl) propane, 2,2-bis (3,5-dimethyl-4-hydroxyphenyl) -propane, 2,2-bis - (3,5-dichloro-4-hydroxyphenyl) -propane, 2,2-bis (3,5-dibromo-4-hydroxyphenyl) -propane and 1, 1-bis (4-hydroxyphenyl) -cyclohexane. In particular, 2,2-bis (4-hydroxyphenyl) propane is preferred. The other diphenols can be used both individually and in a mixture. The molar ratio of diphenols of the formula (Ia) to the optionally used other diphenols of the formula (Ib) should be between 100 mol% (Ia) to 0 mol% (Ib) and 2 mol% (Ia) to 98 mol -% (Ib), preferably between 100 mol% (Ia) to 0 mol% (Ib) and 10 mol% (Ia) to 90 mol% (Ib) and especially between 100 mol% (Ia) to 0 mol% (Ib) and 30 mol% (Ia) to 70 mol% (Ib). The high molecular weight polycarbonate derivatives from the diphenols of the formula (Ia), optionally in combination with other diphenols, can be prepared by the known polycarbonate production processes. The various diphenols can be linked together both statistically and in blocks. The polycarbonate derivatives used can be branched in a manner known per se. If the branching is desired, this can in known manner by condensing small amounts, preferably amounts of 0.05 to 2.0 mol% (based on diphenols), of trifunctional or more than trifunctional compounds, in particular those with three or more than three phenolic hydroxyl groups can be achieved. Some branching agents having three or more than three phenolic hydroxyl groups are: phloroglucinol, 4,6-dimethyl-2,4,6-tri- (4-hydroxyphenyl) -heptene-2,4,6-dimethyl-2,4,6- tri- (4-hydroxyphenyl) heptane, 1,3,5-tri (4-hydroxyphenyl) benzene, 1,1,1-tri- (4-hydroxyphenyl) ethane, tri- (4-hydroxyphenyl) - phenylmethane, 2,2-bis [4,4-bis (4-hydroxyphenyl) cyclohexyl] -propane, 2,4-bis (4-hydroxyphenyl-isopropyl) -phenol, 2,6-is- (2 -hydroxy-5-methylbenzyl) -4-methylphenol, 2- (4-hydroxyphenyl) -2- (2,4-dihydroxyphenyl) -propane, hexa- [4- (4-hydroxyphenyl-isopropyl) -phenyl] - orthoterephthalic acid ester, tetra (4-hydroxyphenyl) methane, tetra- [4- (4-hydroxyphenyl-isopropyl) -phenoxy] -methane and 1,4-bis- [4 ', 4 "-dihydroxytriphenyl) -methyl] -benzene. Some of the other trifunctional compounds are 2,4-dihydroxybenzoic acid, trimesic acid, cyanuric chloride and 3,3-bis- (3-methyl-4-) hydroxyphenyl) -2-oxo-2,3-dihydroindole. As chain terminators known per se regulation of the molecular weight of the polycarbonate derivatives are monofunctional compounds in conventional concentrates. Suitable compounds include phenol, tert. Butylphenols or other alkyl-substituted phenols. For controlling the molecular weight, in particular small amounts of phenols of the formula (Ic) are suitable

(Ic) where R is a branched C ₈ and / or C ₉ alkyl radical. Preferably, in the alkyl radical R, the proportion of CH ₃ protons between 47% and 89% and the proportion of CH and CH ₂ - protons between 53% and 11%; also preferably R is in the o- and / or p-position to the OH group, and more preferably the upper limit of the ortho-portion is 20%. The chain terminators are generally used in amounts of 0.5 to 10, preferably 1, 5 to 8 mol%, based on diphenols used. The polycarbonate derivatives may preferably be prepared in a manner known per se according to the phase boundary behavior (compare H. Schnell "Chemistry and Physics of Polycarbonates", Polymer Reviews, Vol. IX, page 33 et seq., Interscience Publ. In this case, the diphenols of the formula (Ia) are dissolved in an aqueous alkaline phase. For the preparation of copolycarbonates with other diphenols, mixtures of diphenols of the formula (Ia) and the other diphenols, for example those of the formula (Ib), are used. To regulate the molecular weight, chain terminators of, for example, the formula (Ic) can be added. Then, in the presence of an inert, preferably polycarbonate-dissolving, organic phase is reacted with phosgene by the method of interfacial condensation. The reaction temperature is between ⁰ ° C. and 40 ^° C. The optionally used branching agents (preferably 0.05 to 2.0 mol%) can be initially charged with the diphenols in the aqueous alkaline phase or added in the organic solvent before phosgenation become. In addition to the diphenols of the formula (Ia) and, if appropriate, other diphenols (Ib), their mono- and / or bis-chlorocarbonic acid esters may also be used, these being added dissolved in organic solvents. The amount of chain terminators and of branching agents then depends on the molar amount of diphenolate radicals corresponding to formula (Ia) and optionally formula (Ib); with the concomitant use of Chlorocarbonic esters, the amount of phosgene can be reduced accordingly in a known manner. Suitable organic solvents for the chain terminators and optionally for the branching agents and the chloroformates are, for example, methylene chloride, chlorobenzene and in particular mixtures of methylene chloride and chlorobenzene. Optionally, the chain terminators and branching agents used can be dissolved in the same solvent. For example, methylene chloride, chlorobenzene and mixtures of methylene chloride and chlorobenzene serve as the organic phase for the interfacial polycondensation. The aqueous alkaline phase used is, for example, NaOH solution. The preparation of the polycarbonate derivatives by the interfacial process can be catalyzed in a conventional manner by catalysts such as tertiary amines, in particular tertiary aliphatic amines such as tributylamine or triethylamine; the catalysts can be used in amounts of 0.05 to 10 mol%, based on moles of diphenols used. The catalysts can be added before the beginning of the phosgenation or during or after the phosgenation. The polycarbonate derivatives can be prepared by the known method in the homogeneous phase, the so-called "pyridine process" and by the known melt transesterification process using, for example, diphenyl carbonate instead of phosgene. The polycarbonate derivatives may be linear or branched, they are homopolycarbonates or copolycarbonates based on the diphenols of the formula (Ia). By arbitrary composition with other diphenols, in particular with those of the formula (Ib), the polycarbonate properties can be varied in a favorable manner. In such copolycarbonates, the diphenols of the formula (Ia) are present in amounts of from 100 mol% to 2 mol%, preferably in amounts of from 100 mol% to 10 mol% and in particular in amounts of from 100 mol% to 30 mol% %, based on the total amount of 100 mol% of diphenol units contained in polycarbonate derivatives. The polycarbonate derivative may be a copolymer comprising, in particular consisting of, monomer units M1 based on the formula (Ib), preferably bisphenol A, and monomer units M2 based on the geminally disubstituted dihydroxydiphenylcycloalkane, preferably the 4,4 ^' - (3,3,5- Trimethylcyclohexan-1, 1-diyl) diphenols, wherein the molar ratio M2 / M1 is preferably greater than 0.3, in particular greater than 0.4, for example greater than 0.5. It is preferred that the polycarbonate derivative has a weight average molecular weight of at least 10,000, preferably from 20,000 to 300,000. In principle, component B may be substantially organic or aqueous. Substantially aqueous means that up to 20% by weight of component B) can be organic solvents. Substantially organic means that up to 5% by weight of water may be present in component B). Component B preferably contains one or consists of a liquid aliphatic, cycloaliphatic, and / or aromatic hydrocarbon, a liquid organic ester and / or a mixture of such substances. The organic solvents used are preferably halogen-free organic solvents. Particularly suitable are aliphatic, cycloaliphatic, aromatic hydrocarbons, such as mesitylene, 1, 2,4-trimethylbenzene, cumene and solvent naphtha, toluene, xylene; (organic) esters such as methyl acetate, ethyl acetate, butyl acetate, methoxypropyl acetate, ethyl 3-ethoxypropionate. Preference is given to mesitylene, 1, 2,4-trimethylbenzene, cumene and solvent naphtha, toluene, xylene, methyl acetate, ethyl acetate, methoxypropyl acetate. Ethyl 3-ethoxypropionate. Very particular preference is given to mesitylene (1, 3,5-trimethylbenzene), 1, 2,4-trimethylbenzene, cumene (2-phenylpropane), solvent naphtha and ethyl 3-ethoxypropionate. A suitable solvent mixture comprises, for example, L1) 0 to 10% by weight, preferably 1 to 5% by weight, in particular 2 to 3% by weight, mesitylene, L2) 10 to 50% by weight, preferably 25 to 50% by weight %, in particular 30 to 40 wt.%, 1-methoxy-2-propanol acetate, L3) 0 to 20 wt.%, preferably 1 to 20 wt.%, in particular 7 to 15 wt.%, 1 , 2,4-trimethylbenzene, L4) 10 to 50 wt.%, Preferably 25 to 50 wt.%, In particular 30 to 40 wt.%, Ethyl 3-ethoxypropionate, L5) 0 to 10 wt. , preferably 0.01 to 2 wt .-%, in particular 0.05 to 0.5 wt .-%, cumene, and L6) 0 to 80 wt .-%, preferably 1 to 40 wt .-%, in particular 15 to 25 wt .-%, solvent naphtha, wherein the sum of components L1 to L6 always gives 100 wt .-%. The polycarbonate derivative typically has a weight average molecular weight of at least 10,000, preferably from 20,000 to 300,000.

The preparation may contain in detail: A) 0.1 to 10 wt .-%, in particular 0.5 to 5 wt .-%, of a binder with a polycarbonate derivative based on a geminal disubstituted dihydroxydiphenylcycloalkane, B) 40 to 99.9 wt %, in particular 45 to 99.5% by weight, of an organic solvent or solvent mixture, C) 0.1 to 6% by weight, in particular 0.5 to 4% by weight, of a colorant or colorant mixture, D ) 0.001 to 6 wt .-%, in particular 0.1 to 4 wt .-%, of a functional material or a mixture of functional materials, E) 0.1 to 30 wt .-%, in particular 1 to 20 wt .-%, additives and / or auxiliaries, or a mixture of such substances.

As component C, if a colorant is to be provided, basically any colorant or colorant mixture comes into question. Colorants are all colorants. This means that it can be both dyes (a review of dyes Ullmann's Encyclopedia of Industrial Chemistry, Electronic Release 2007, Wiley publishing house, chapter "Dyes, General Survey") as well as pigments (a review of organic and inorganic pigments are Ullmann's Encyclopedia of Industrial Chemistry, Electronic Release 2007, Wiley Verlag, chapter "Pigments, Organic" and "Pigments, Inorganic"). Dyes should be soluble or (stably) dispersible or suspendible in the component B solvents. Furthermore, it is advantageous if the colorant at temperatures of 160 ⁰ C and more for a period of more than 5 min. stable, in particular color-stable. It is also possible that the colorant is subjected to a predetermined and reproducible color change under the processing conditions and is selected accordingly. In addition to the temperature stability, pigments must be present in particular in the finest particle size distribution. In the practice of ink jet printing, this means that the particle size should not exceed 1, 0 microns, otherwise blockages in the printhead are the result. As a rule, nanoscale solid-state pigments and dissolved dyes have proven their worth. The colorants may be cationic, anionic or even neutral. Just as examples of colorants that can be used in ink-jet printing are called its: Brilliant Black Cl. No. 28440, Chromogen Black Cl. No. 14645, direct deep black E Cl. No. 30235, true black salt B Cl. No. 37245, true black salt K Cl. No. 37190,

Sudan Black HB Cl. 26150, Naphtol Black Cl. No. 20470, Bayscript® Black Liquid, Cl. Basic Black 11, Cl. Basic Blue 154, Cartasol® Turquoise K-ZL liquid, Cartasol® Turquoise K-RL liquid (Cl. Basic Blue 140), Cartasol Blue K5R liquid. Suitable are the

Further z. For example, the commercially available dyes Hostafine® Black TS liquid (sold by Clariant GmbH Germany), Bayscript® Black Liquid (Cl mixture, sold by Bayer AG Germany), Cartasol® Black MG Liquid (CI Basic Black 11, Registered Trademark of Clariant GmbH Germany), Flexonylschwarz® PR 100 (E Cl. No. 30235, marketed by Hoechst AG), Rhodamine B, Cartasol® Orange

K3 GL, Cartasol® Yellow K4 GL, Cartasol® K GL, or Cartasol® Red K-3B. Furthermore, as soluble colorants, anthraquinone, azo, quinophthalone, coumarin, methine, Perinone, and / or pyrazole, for example, under the brand name Macrolex® available, find use. Further suitable colorants are described in the reference Ullmann ^'s Encyclopedia of Industrial Chemistry, Electronic Release 2007, Wiley Verlag, chapter "Colorants Used in Ink Jet Inks". Well-soluble colorants lead to an optimal integration into the matrix or the binder of the print layer. The colorants may be added either directly as a dye or pigment or as a paste, a mixture of dye and pigment together with another binder. This additional binder should be chemically compatible with the other components of the formulation. If such a paste is used as a colorant, the amount of component B refers to the colorant without the other components of the paste. These other components of the paste are then subsumed under the component E. When using so-called colored pigments in the scale colors cyan-magenta-yellow and preferably also (soot) black solid color images are possible.

Component D comprises substances that can be seen directly by the human eye or by the use of suitable detectors using technical aids. Here are the materials known to those skilled in the art (see also van Renesse, Optica! Document security, 3rd ed., Artech House, 2005), which are used to secure value and security documents. These include luminescent substances (dyes or pigments, organic or inorganic) such as photoluminophores, electroluminophores, Antistokes luminophores, fluorophores but also magnetizable, photoacoustically addressable or piezoelectric materials. Furthermore, Raman-active or Raman-reinforcing materials can be used, as well as so-called barcode materials. Again, the preferred criteria are either the solubility in the component B or pigmented systems particle sizes <1 micron and a temperature stability for temperatures> 160 ⁰ C in the sense of the comments on component C. Functional materials can be added directly or via a paste, ie a mixture with a further binder, which then forms part of component E, or the binder of component A.

In the case of inkjet inks, the component E comprises substances usually prepared such as anti-foaming agents, setting agents, wetting agents, surfactants, flow agents, dryers, catalysts, (light) stabilizers, preservatives, biocides, surfactants, organic polymers for viscosity adjustment, buffer systems, etc. Suitable adjusting agents are commercially available actuating salts. An example of this is sodium lactate. As biocides, all commercially available preservatives which are used for inks come into question. Examples are Proxel®GXL and Parmetol® A26. Suitable surfactants are all commercially available surfactants which are used for inks. Preferred are amphoteric or nonionic surfactants. Of course, it is also possible to use special anionic or cationic surfactants which do not alter the properties of the dye. Examples of suitable surfactants are betaines, ethoxylated diols, etc. Examples are the product series Surfynol® and Tergitol®. The amount of surfactants is particularly selected in an application for ink jet printing, for example, provided that the surface tension of the ink is in the range of 10 to 60 mN / m, preferably 20 to 45 mN / m, measured at 25 ^° C. A buffer system can be set up which stabilizes the pH in the range from 2.5 to 8.5, in particular in the range from 5 to 8. Suitable buffer systems are lithium acetate, borate buffer, triethanolamine or acetic acid / sodium acetate. A buffer system will be considered in particular in the case of a substantially aqueous component B. To adjust the viscosity of the ink (possibly water-soluble) polymers can be provided. Here all suitable for conventional ink formulations polymers come into question. Examples are water-soluble starch, in particular with an average molecular weight of 3,000 to 7,000, polyvinylpyrrolidone, in particular with an average molecular weight of 25,000 to 250,000, polyvinyl alcohol, in particular with an average molecular weight of 10,000 to 20,000, xanthan gum, carboxymethylcellulose, ethylene oxide / propylene oxide Block copolymer, especially having an average molecular weight of 1,000 to 8,000. An example of the latter block copolymer is the product series Pluronic®. The proportion of biocide, based on the total amount of ink, may be in the range of 0 to 0.5% by weight, preferably 0.1 to 0.3% by weight. The proportion of surfactant, based on the total amount of ink, can range from 0 to 0.2 wt .-%. The proportion of adjusting agents, based on the total amount of ink, 0 to 1 wt .-%, preferably 0.1 to 0.5 wt .-%, amount. The auxiliaries also include other components, such as, for example, acetic acid, formic acid or n-methyl-pyrrolidone or other polymers from the dye solution or paste used. With regard to substances which are suitable as component E, reference is additionally made, for example, to Ullmann's Encyclopedia of Chemical Industry, Electronic Release 2007, Wiley Verlag, chapter "Paints and Coatings", section "Paint Additives". The features of the polymer layer composite according to the invention and / or of a security and / or security document have the same advantages as the corresponding features of the production method according to the invention. A distribution of the first, preferably personalizing and / or individualizing, information and optionally a second, possibly also personalizing and / or individualizing, information in different levels of the polymer layer composite or security and value document, so that at different viewing angles at least one color change reproduced information, usually also an information content change occurs, provides a security feature, which offers a very high security against falsification. A high degree of protection against counterfeiting is also given in relation to an imitation, since a high-resolution register-accurate printing of the first information, which comprises, for example, a colored face image, can only be realized with very high technical complexity if the colored information is applied to different levels of the polymer layer composite or and / or security document is distributed so that in addition a viewing angle-dependent color-tilting effect is effected. When using a polycarbonate-based ink and substrate layers which are also produced on a polycarbonate basis, laminating results in a monolithic body or partial body in which no transitions of the substrate layers used in the production are more recognizable. The printed ink is then also completely integrated in the monolithic body or partial body, ie the monolithic polymer layer composite or partial polymer layer composite. As a result, large-area printing can be carried out with the first personalizing and / or individualizing information, without the risk of delamination, which often occurs when other inks and / or printing inks are used.

A high-pressure technical application of the first information can be done for example by means of ink jet printing on the different substrate layer surfaces and thus carried out with a uniform and simple, very well-controlled printing technology.

Fig. 5 is a schematic representation of a polymer layer composite, similar to that of Fig. 4b, in which additionally printed with a luminescent colors substrate layer surface printed below the printouts of the first information Substrate layer surfaces is provided which emits surface white light upon UV excitation.

By way of example, a method for producing a value and / or security document, which is designed as a polymer layer composite, will be explained with reference to FIG. In Fig. 1, an apparatus for producing a polymer layer composite is shown. The device comprises a plurality of rollers on which polymer films, preferably polycarbonate films, are wound up. To produce a polymer layer composite, at least three polymer layers are required as substrate layers if a first information to be introduced is to be protected against manipulation in the interior of the polymer layer composite to be produced. The polymer films are arranged on the rollers 2-4. Optionally, one or more further, in particular one to twelve, more preferably two to ten and particularly preferably four to six, polymer layers may be supplied on rollers. These possible additional polymer layers, which are made available as a substrate, are symbolized via the roller 5, which is shown in dashed lines. The polymer layers 6-9 provided or supplied by the rollers 2-5 have thicknesses between 5 μm and 350 μm, preferably thicknesses between 50 μm and 150 μm. The individual polymer layers 6-9 may all have the same thickness or different thicknesses.

A preferably designed as a computer control unit 10, a first information, for example in the form of a computer data set supplied. The first information is preferably personalizing and / or individualizing information and may include, for example, a colored face image (passport photograph) as well as personal information such as last name, first name, date of birth, place of residence, place of birth, street, house number, postal code, etc. The control unit 10 is designed such that it decomposes the first information into at least two pressure extracts, each of which comprises a partial information of the first information. For example, three monochrome color separations in a cyan-magenta-yellow color space or color system are produced by the colored face image. In addition, a fourth color separation for black and / or gray image components can be created. The at least two color print separations, which are identical, for example, to the monochrome color separations or represent a combination of two monochrome color separations, are transmitted to printing units 11-14. Likewise, the first information can be decomposed into printing extracts, the are each multi-colored, that is, include pixels to be printed with inks and / or inks having a different color. These printing units 11-14 are formed as digital printing units, which means that they perform a digital printing process. Preferably, the printing units 11-14 are formed as inkjet printing units. In some embodiments, the various printing units 11-14 may also print by various digital printing methods. Ink jet printing units are particularly well suited for printing multicolor print separations, so that the individual pixels of a print separation, which have different colors within the print separation, exactly their predetermined distances and positions.

In one embodiment, in which only the three polymer layers 6-8 are provided by the rollers 2-4, for example, two pressure separations are printed in register on opposing surfaces of the polymer layer 7 via the printing units 11 and 12. This means that on the substrate layer provided by the polymer layer 7 on an upper side 15, i. an upper substrate layer surface is printed by the printing unit 11, for example a print separation, comprising one half of the alternately assigned pixels of the first information. On a lower side 16 (a lower substrate layer surface) of the substrate layer provided by the polymer layer 7, the printing unit 12 imprints the second printing separation, which comprises a different half of the alternately assigned pixels of the first information, precisely in register with the first print separation.

In other embodiments, printing units 11-14 may each print out a monochromatic color separation of a tri-color black color system, the black color separation also being considered here as a monochromatic color expression. This means that the printing units 13 and 14 print on the polymer layer 9 also register exactly two different print separations. In such a case, it is advantageous if between the polymer layers 7 and 9, a further transparent polymer layer is inserted (not shown), so that the printed by the printing units 12 and 13 printed separations in the finished polymer layer composite are spaced from each other. However, this is not mandatory. In other embodiments, printing of the inner substrate layer surfaces of the outer substrate layers (polymer layers) may also be provided. The polymer layers 6-8 and 6-9 are guided over deflection rollers 17 and combined to form a polymer layer stack or substrate layer stack 18. The gathering or merging of the individual polymer layers 6-9 is carried out so, at least if the at least two printing extracts are printed on different substrates or polymer layers 6-9 and they have the same expansion and / or shrinkage properties in a lamination, that the individual pressure excerpts, ie the printed print separations, are arranged in the substrate layer stack 18 in register with each other.

Subsequently, the substrate layers or polymer layers 6-8 or 6-9 are joined together to form a composite body. The joining takes place via a lamination process, which is preferably carried out via a hot and cold press 19. The interconnected substrate layers or polymer layers 6-8 and 6-9 are fed to a separation unit 20, which is designed for example as a punch and a security and / or value document 21, which is a polymer layer composite, for example, punched out and / or cut.

It will be understood by those skilled in the art that the method of preparation is described in a highly simplified manner. Of course, further method steps and device parts may be inserted and / or added, which are provided for introducing further security elements and / or security features for a security and / or value document. For example, a laser engraving station may be provided and / or a hologram may be added in the form of a further layer, preferably a developed photosensitive polymer layer, prior to lamination. Explicitly, other non-digital printing methods are also possible, such as offset printing and screen printing, which introduce printing technology security features such as guilloches or OVI colors. The document does not have to be printed digitally.

In the manufacturing process described in connection with FIG. 1, the individual substrate layers are supplied in the form of polymer layers provided on rolls. In another embodiment of the method, the individual polymer layers or substrate layers can be printed and / or gathered in the form of sheets. A register-accurate alignment is preferably carried out via a so-called three-point system of the individual compiled sheets. Before the Lamination process, in which the individual polymer layers are joined to the composite body, a stapling, for example via an ultrasonic bonding and / or a targeted introduction of laser radiation in individual boundary layers of adjacent substrate layers locally at one or more locations. Other stapling methods, such as heated staples, can of course be used. A separating step can be omitted if the sheets are precisely matched to the polymer layer composite to be produced.

FIG. 2 a again schematically illustrates the construction of a value and / or security document 21 designed as a polymer layer composite, in which a first information 30 is stored by printing technology, which is shown in FIG. 2 b.

In Fig. 2b, a line of a print image of a first information 30 is shown schematically. The pixels 32 are alternately assigned two halves 29, 31, which yield the two pressure separations 27, 28 according to FIG. 2a.

For illustrative purposes, print separations are shown greatly enlarged and the individual substrate layers 22, 23, 24 are shown spaced apart from one another. This applies to all figures described here. In the finished value and / or security document 21, these layers are preferably monolithically, provided that the substrate layers all consist of the same polymer material, are bonded to one another in a material-locking manner. An upper substrate layer surface 25 of the substrate layer 23 is printed with a print separation 27 comprising a first half 29 of the pixels 32 of a first information 30. A lower substrate layer surface 26 of the substrate layer 23 is printed accordingly with a second pressure separation 28, which comprises a second half 31 of the pixels 32 of a first information 30. In order to protect the printed partial information of the two printing extracts 28, 28 against tampering and / or adulteration, the substrate layers 22 and 24 are provided on the outside. In the finished polymer layer composite, the two pressure separations 27, 28 are arranged or imprinted in different planes of the security and / or value document 21.

In a plan view of FIG. 2 a along a first viewing direction 33, the first information 30 is reproduced. When viewing under a different viewing direction 34 results in a color change, since the pixels (pixels) of the first pressure separation 27 and the second pressure separation 28 partially overlap. Further are at least partially visible pixels 35, which are otherwise hidden by the pixels of the first printing separation 27 in plan view along the viewing direction 33.

As a rule, at least the substrate layers 22 and 23 are transparent, preferably also the substrate layer 24. In one embodiment, one of the substrate layers 22-24 is translucent, preferably the substrate layer 23 arranged between pressure extensions 27 and 28. FIG.

In Fig. 3, a first information 30 is shown schematically flat. The pixels 32 may have any different (basic) colors. The given digits indicate how the pixels are alternately assigned to two print separations along second orthogonal directions 36, 37.

FIG. 4a schematically shows an exemplary decomposition of the first information 30 in three printing extracts 41-43. Here, the print separations 41-43 are monochrome color separations of a tri-color color space, for example, a cyan-magenta-yellow color space. In the polymer layer composite 40 formed from the substrate layers 51-54, the print separations 41-43 are printed on mutually spaced substrate layer surfaces 56, 57, 58 of the substrate layers 52 and 54. In plan view along the viewing direction 33 thus results in the complete first information. When viewed obliquely from top left along the viewing direction 34, however, results in a different view. Also previously hidden areas or pixels 35 of the printing extracts 42, 43 are visible. In these pixels 35 becoming visible, a second piece of information can be stored.

In Fig. 4b these pixels uniformly a second information, which is shown in black assigned. The printing separation 43, which is introduced furthest away from the viewing side 50 of the polymer layer composite 40, can in one embodiment be made on a part of an electronic circuit and / or a microchip (not shown) which are inserted into the polymer layer composite. As a result, for example, the microchip is protected against unnoticed exchange. Likewise, a diffractive element can be secured.

In Fig. 4c, another embodiment is shown. In this, each of an excellent direction 36, the individual pixels that are for storage of the second information are available, set differently colored according to a color scheme. Such an exemplary color scheme is indicated in detail in FIG. 4d. Depending on the design of adjacent pixels on the right and left (unprinted or printed with one of the primary colors), the color for the hidden in plan view, possibly set at a different viewing angle, the pixels becoming visible. Missing pixels on the edge are assumed to be non-printed pixels.

It will be apparent to those skilled in the art that more complex schemes can be used to achieve a desired color-tilt effect for the security feature. For this purpose, for example, an embodiment of the next but one neighboring pixels of the pixels in above and / or below arranged pressure excerpts, etc. may be included.

Likewise, of course, embodiments are advantageously possible in which a predetermined second information is stored in the originally hidden pixels 35, which become visible only when the viewing direction 34 deviates from the top view 33. This information can be extracted, for example, by subtracting two views of the polymer layer composite at predetermined viewing angles (or viewing directions 33, 34) and then preferably evaluated by machine.

The first information and optionally also a predetermined second information preferably comprise individualizing and / or personalizing information. It is likewise advantageous to integrate color transitions, for example an iris print, into the first information. In this case, it can be provided that the pixels of the first color are printed in a print separation and the pixels of the second color are printed in a second print separation. However, it is also possible to distribute the pixels in other ways between two or more separations, which are printed on different substrate layer surfaces, which are preferably spaced from each other in the formed polymer layer composite.

FIG. 5 shows a further embodiment of a polymer layer composite 40, in which underneath the print separations 41-43 according to FIG. 4b a lower substrate layer surface 59 of the substrate layer 54 with luminescent colorants 60 is printed. The substrate layer surface 59 is preferably printed such that flat surface white light is emitted when excited by UV radiation. The pixels of the print separations 41-43 filter this white light, so that the first information is colored in plan view along the viewing direction 33 is visible. At different viewing angles (for example, under the viewing direction 34), a double filtering takes place, so that again a color change can be observed.

If one of the substrate layers, which is arranged between the two of the print separations 41-43, is translucent, for example the substrate layer 53, a different view is visible in a plan view without UV excitation than in the case of UV excitation. Without UV excitation, only the information portions of the print separations 41 and 42 are visible. With UV excitation, the information portions of the pressure extension 43 are also visible.

If, in addition, the substrate layers 51, 52 and 54, 55 are transparent, then the embodiment according to FIG. 5 also represents a transparency. Here, it is assumed that the luminescent colors are transparent in the visible wavelength range.

The transparency can of course be realized without the luminescent printing.

In other embodiments, the luminescent substances can also be introduced into this substrate layer without printing, for example during production of one of the substrate layers, and reach the polymer layer composite via this.

In the described embodiments, the individual print separations are preferably applied by means of ink jet printing.

The substrate layers are preferably polycarbonate-based polymer layers. The ink used is preferably a liquid preparation which is likewise produced on a polycarbonate basis. Examples of a preparation of a polycarbonate derivative which can be used according to the invention, a preparation of a liquid preparation suitable for the production of an ink-jet printing ink and the preparation of a first inkjet printing ink which can be used according to the invention are given below.

Example 1: Preparation of a polycarbonate derivative which can be used according to the invention

149.0 g (0.65 mol) of bisphenol A (2,2-bis- (4-hydroxyphenyl) -propane, 107.9 g (0.35 mol) of 1,1-bis- (4-hydroxyphenyl) -3 , 3,5-trimethylcyclohexane, 336.6 g (6 mol) of KOH and 2700 g of water are dissolved in an inert gas atmosphere with stirring, then a solution of 1.88 g of phenol in 2500 ml of methylene chloride is added 198 g (2 mol) of phosgene were introduced at pH 13 to 14 and 21 to 25 ° C. Thereafter, 1 ml of ethyl piperidine was added and the mixture was stirred for another 45 min washed neutral with water and freed from the solvent.

The polycarbonate derivative showed a relative solution viscosity of 1.263. The glass transition temperature was determined to be 183 ^° C. (DSC).

Example 2: Preparation of a liquid preparation suitable for the production of an ink jet ink

A liquid preparation was prepared from 17.5 parts by weight of the polycarbonate derivative of Example 1 and 82.5 parts by weight of a Lsgm.-blend according to Table I.

Table I

There was obtained a colorless, highly viscous solution having a solution viscosity at room temperature of 800mPas.

Example 3: Preparation of a first ink jet printing ink which can be used according to the invention

10 g of polycarbonate solution from Example 2 and 32.5 g of the solvent mixture from Example 2 were homogenized with a magnetic stirrer in a 50 mL wide-necked threaded glass (4% strength PC solution). There was obtained a colorless, low-viscosity solution having a solution viscosity at 20 ⁰ C of 5.02 mPa.s.

The polycarbonate solution obtained was additionally admixed with about 2% of Pigment Black 28. The result is an ink by means of which black and white images can be printed on polycarbonate films. By an equivalent addition of other pigments or dyes can be prepared according to monochrome and / or colored inks.

A change in the resolution of a pixel pattern printed with the ink almost does not occur in the joining process in which the substrate layer printed with the pixel pattern is connected to a substrate layer arranged above it. This means that the pixel pattern will remain in almost the same resolution even after lamination.

An optical examination of the composite revealed otherwise no detectable phase boundary. The composite proved to be a monolithic block, which also resists delamination.
