Description

WO 2009/056351 PCT/EP2008/009333 Method for producing a multilayer polymer structure having a multilayer personalization and/or individualization feature 5 The invention relates to a method for producing a polymer laminate comprising a plurality of substrate layers, in which at least one first personalizing and/or individualizing piece of information is stored by printing, and to such a polymer laminate. The 10 invention also relates to a use of such a method or of a polymer laminate for the production of a security and/or valuable document and/or a use of such a polymer laminate as a security and/or valuable document. 15 Prior Art and Background of the Invention Modern security and/or valuable documents will be or are in the form of a polymer laminate or produced from such a polymer laminate or comprise such a polymer 20 laminate. Security and/or valuable documents comprise as a rule personalizing and/or individualizing information which permits assignment of the security and/or valuable document to a person and/or a group of persons, articles and/or entities. Individualizing 25 information is/may comprise, for example, a serial number or an indication of the issue in authority. The personalizing and/or individualizing information moreover represents a security feature. A security feature is a feature of a security and/or valuable 30 document which is intended to prevent or at least to complicate copying and/or forgery and/or imitation of the valuable and/or security document. Personalized information is regarded as being 35 information which comprises information assignable to a person. This may be, for example, image information, for example a passport picture, a fingerprint, etc., or alphanumeric character sequences, such as a name, an WO 2009/056351 PCT/EP2008/009333 -2 address, a place of residence, a date of birth, etc. The following may be mentioned mainly by way of example as security and/or valuable documents: identity papers, 5 passports, ID cards, access monitoring passes, visas, control characters, tickets, driving licences, motor vehicle documents, banknotes, checks, postage stamps, credit cards, bank cards, any desired chip cards and adhesive labels (e.g. for product security). 10 The prior art discloses different methods for producing valuable and/or security documents. For example, the publications US 6,022,429, US 6,264,296, US 6,685,312, US 6,932,527, US 6,979,141 and US 7,037,013 describe 15 those methods in which an inkjet print which is to be protected with a protective coat or a protective film as protection from mechanical and/or chemical damage and manipulations is applied to prepare blanks. By means of this method, personalizing and/or 20 individualizing information can be stored by printing in color in the security and/or valuable document. However, the resulting security and/or valuable documents have only relatively low security against manipulations because the imprinted information is 25 printed on completely relatively close to the surface and the protective layer comprising lacquer or a protective film generally does not form a monolithic, material bond to the card blank and is therefore detachable and/or removable. Subsequent manipulation of 30 the printed matter is possible. DE 41 34 539 Al discloses a recording medium having colored image information, which is in particular a value card or identity card, and a method for the 35 production. The image information is divided into a light/dark part and a colored part. The light/dark part, which is intended for the visual impression, is introduced in highly resolved form into the recording WO 2009/056351 PCT/EP2008/009333 -3 medium. This part is superposed in a congruent manner with the colored image information so that an integral overall impression results. In order to ensure security against forgery, one of the parts of the image 5 information is introduced in substantially forgery proof form into a card structure. Embodiments are described in which, for example, the light/dark information is introduced by means of laser engraving into a transparent film which is applied on a printed 10 inlay. The colored part is printed on an ink-accepting layer applied to the film or on the transparent film. In another embodiment, the inlay is provided by an electrophotographic method with the colored part of the image information. A thin transparent cover film into 15 which the light/dark part of the image information is burned by means of laser engraving is then arranged over the colored fixed toner image. Yet another embodiment envisages that the inlay will be provided with black/white information with the use of a 20 conventional method such as, for example, inkjet printing, and will be covered in the subsequent step with a substantially transparent plastics film which is suitable for accepting migrating inks. The colored image parts are introduced into the depth of the cover 25 layer by means of migrating inks. Here, the cover film can first be printed with the colored image information. Under the action of heat, the ink migrates into the interior of the cover layer until crosslinking of the cover layer is initiated by UV radiation, which 30 crosslinking stops further migration. In yet another embodiment, the color information is first introduced into the cover layer and light/dark information is applied thereafter by conventional printing methods. Once again, the problem arises that the film used, 35 under which or in which a part of the information is arranged does not form a monolithic bond to the inlay and can therefore be removed and/or replaced for forgery. In a number of embodiments described, a part WO 2009/056351 PCT/EP2008/009333 -4 of the information is moreover applied directly on the surface and is particularly easily accessible to forgery and/or manipulation. 5 The publications US 7,005,003 B2, EP 0 131 145 B1, US 5,734,800 and US 6,765,693 Bl describe methods for printing colored images with different color separations. 10 Technical Problem of the Invention The technical problem of the invention is to provide a method for producing a polymer laminate and such a polymer laminate in which at least one first 15 personalizing and/or individualizing piece of information is or will be stored by printing so that the first personalizing and/or individualizing information is better protected from manipulation and/or forgery and/or such a polymer laminate is better 20 protected from imitation than in the case of the polymer laminate systems known from the prior art and which therefore can be used in particular as a valuable and/or security document or as a constituent of a valuable and/or security document or as part of a 25 method for producing such a valuable and/or security document. Basic Principles of the Invention and Preferred Embodiments 30 In order to solve the problem, a method for producing a polymer laminate comprising a plurality of substrate layers in which at least one first personalizing and/or individualizing piece of information is stored by 35 printing is proposed, which method comprises the steps: provision of a plurality of polymer layers as the substrate layers; printing of the first personalizing and/or individualizing information on at WO 2009/056351 PCT/EP2008/009333 -5 least one substrate layer, combination of the substrate layers to form a substrate layer stack, and lamination of the substrate layers to form a polymer laminate, it being envisaged according to the invention that the 5 first personalizing and/or individualizing information is divided into at least two print extracts which in each case comprise partial information of the first personalizing and/or individualizing information, and printing of the first personalizing and/or 10 individualizing information is effected by printing of the at least two print extracts on at least two different substrate layer surfaces in a matching manner so that the printed print extracts lie in register one on top of the other in the polymer laminate and 15 together reproduce the first personalizing and/or individualizing information, the substrate layers being combined so that the substrate layer surfaces printed with the at least two print extracts are inner surfaces in the substrate layer stack. According to the 20 invention, a polymer laminate which is produced by lamination of a plurality of substrate layers and in which at least one first personalizing and/or individualizing piece of information is stored by printing is thus obtained, the substrate layers being 25 polymer layers and the first personalizing and/or individualizing information being divided into at least two print extracts which in each case comprise partial information of the first personalizing and/or individualizing information, and the at least two print 30 extracts are printed in at least two planes a distance apart or the at least two printed print extracts are arranged in at least two planes a distance apart so that the printed print extracts lie one on top of the other in register in the polymer laminate and together 35 reproduce the first personalizing and/or individualizing information, the planes which are printed with the at least two print extracts or in which the at least two print extracts are arranged WO 2009/056351 PCT/EP2008/009333 -6 being inner planes. The polymer laminate obtained therefore comprises, incorporated in a laminate body, first personalizing information which is stored in at least two planes a distance apart so that they together 5 reproduce the first personalizing information. Compared with the application of first individualizing and/or personalizing information in the interior of a polymer laminate according to the prior art, increased security against forgery is achieved here since information 10 components must be manipulated at least in two planes. The first personalizing and/or individualizing information is preferably colored or multicolored. This means that the first personalizing information cannot 15 be reproduced with a single printing ink. Information is regarded as being multicolored if it gives rise to at least two color impressions for a viewer, brightness differences not being intended to represent different color impressions. Colored is regarded as information 20 which gives rise to more than three different color impressions, of which at least one color impression is preferably brought about or can preferably be brought about by additive color mixing (in the case of luminescent colors) or subtractive color mixing of base 25 colors (in the case of so-called surface colors) which span a color space. Black and gray steps are not regarded as colors here. Particularly preferably, the first personalizing and/or individualizing information comprises a colored or multicolored facial image of a 30 person. Security against manipulation is increased by virtue of the fact that the at least two print extracts are each colored. Here, this may be monochrome, i.e. single-colored, and/or multicolored. In a preferred embodiment, the at least two print extracts comprise a 35 monochrome color separation of an n-color system, in particular a three-color system, or of an n-color-black system, in particular of a three-color-black system. All known n-color systems with which colored or WO 2009/056351 PCT/EP2008/009333 -7 multicolored information can be represented are possible here, the colored information comprising more color values than the number of printing inks used for the production. With a three-color system, for example 5 with the colors yellow, magenta, cyan, a major part of the color space perceptible to humans can increase by utilizing the color subtraction in the human perception of colors. However, it is also possible to use color systems which use more than three colors or more than 10 three colors and black, for example six colors plus black. In one embodiment of the invention, the at least two print extracts comprise m monochrome color separations 15 which in each case are printed on different substrate layer surfaces. Here, m is an integer which as a rule will correspond to a number n which indicates the number of colors of the color system used. However, it is also conceivable for the first personalizing and/or 20 individualizing information to be divided into a larger number of monochrome print extracts so that, for individual or all colors of the color system, there are two monochrome print extracts which in each case comprise partial information of the first personalizing 25 and/or individualizing information. These several monochrome print extracts for a color can of course comprise different partial information of the first personalizing and/or individualizing information. 30 Orientation of the at least two print extracts in register is particularly easy to realize in an embodiment in which two of the print extracts or the at least two print extracts are printed in register on opposite surfaces of the same substrate layer, the 35 printed print extracts being mirror images of one another when the surfaces are viewed. This means that one print extract which is printed on the top of the substrate layer which faces the top in the substrate WO 2009/056351 PCT/EP2008/009333 -8 stack from where the individualizing and/or personalizing first information is to be perceptible is not printed as a mirror image. The print extract is then printed as a mirror image on the bottom of the 5 same substrate layer if the substrate layer is now viewed from the bottom. When viewed from the top, the at least two print extracts correctly supplement one another to give the personalizing and/or individualizing first information. 10 In order to be able correctly to perceive the first personalizing and/or individualizing information, the substrate layers which are arranged between the individual print extracts and above them are of course 15 transparent or, if they are not transparent, at least translucent. Preferably, all these substrate layers are transparent. If the substrate layer or at least one of the substrate 20 layers between the at least two substrate layer surfaces on which the at least two print extracts, which in each case comprise partial information of the first individualizing and/or personalizing information, are printed is translucent, it is particularly 25 preferable if the entire polymer laminate is translucent, i.e. not opaque, at least in the region in which the first individualizing and/or personalizing information is stored. In this way, it is possible to produce a personalized and/or individualized 30 transparent register which represents the total information when viewed with backlighting. It is therefore envisaged in one embodiment that the polymer layers will all be provided as transparent 35 and/or translucent polymer layers at least in a region in which one of the substrate layer surfaces is printed with one of the print extracts, or at least in a region in which one of the substrate layers arranged above or WO 2009/056351 PCT/EP2008/009333 -9 below in the polymer laminate is or will be printed with one of the print extracts, at least one, preferably exactly one, polymer layer which is arranged between two of the at least two print extracts being 5 provided as a translucent polymer layer. The other polymer layers are preferably all transparent. In another embodiment, it is envisaged that at least two of the at least two print extracts are printed on 10 substrate layer surfaces of different substrate layers. In order, for example, to avoid reflection of one or more print extracts, as this is required when bottoms of the substrate layers arranged one on top of the 15 other are printed, it is preferred in one embodiment that all of the at least two print extracts are printed on substrate layer surfaces of different substrates. In order to ensure that the different printed print 20 extracts are also arranged in different planes in the polymer laminate produced, it is envisaged in one embodiment of the invention that the plurality of substrate layers be combined so that the substrate layer surfaces, which are printed with one of the at 25 least two print extracts, are not directly adjacent in the substrate stack. If the at least two print extracts are not printed on different substrate layer surfaces of one and the same 30 substrate layer, the substrate layers are preferably oriented relative to one another on combination so that the at least two print extracts are arranged in register one on top of the other in the substrate layer stack. This requires that the substrate layers be 35 substantially formed from the same polymer or at least have the same expansion and/or shrinkage properties in the case of material bonding of the individual substrate layers on lamination.

WO 2009/056351 PCT/EP2008/009333 - 10 In principle, all materials customary in the area of security and/or valuable documents can be used as materials for the polymer layers. The polymer layers 5 may be formed, identically or differently, on the basis of a polymer material from the group consisting of PC (polycarbonate, in particular bisphenol A polycarbonate), PET (polyethylene glycol terephthalate), PMMA (polymethyl methacrylate), TPU 10 (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. The use of PC materials is preferred, it 15 also being possible, for example, but by no means necessary, to use so-called low Tg materials, in particular for the polymer layers on which the print extracts are printed and/or polymer layers which are bonded to the polymer layer or layers which are 20 printed, in particular in the side with the inkjet imprint. Low-Tg materials are polymers whose glass transition temperature is below 140*C. The polymer layers may be used in filled or unfilled 25 form. The filled polymer layers contain in particular colorants, which may be both dyes and color pigments, or other fillers. The polymer layers may also be colored by means of dyes or may be colorless and in the latter case transparent or translucent. 30 It is preferable if the base polymer of at least one of the polymer layers to be bonded contains identical or different groups reactive with one another, reactive groups of a first polymer layer reacting with one 35 another and/or with reactive groups of a second polymer layer at a lamination temperature of less than 200'C. As a result, the lamination temperature can be reduced without endangering the intimate bonding of the WO 2009/056351 PCT/EP2008/009333 - 11 laminated layers thereby. In the case of different polymer layers having reactive groups, this is due to the fact that the different polymer layers can no longer be readily delaminated owing to the reaction of 5 the respective reactive groups with one another and the formation of covalent chemical bonds. This is because reactive coupling takes place between the polymer layers, equivalent to reactive lamination. Furthermore, owing to the low lamination temperature, it is made 10 possible for a change in the colored printing ink, in particular a color change, to be prevented. It is preferable if the glass transition temperature Tg of the at least one polymer layer before the thermal lamination is less than 140 0 C (or even less than 120 0 C 15 or less than 100 0 C), the glass transition temperature of this polymer layer after the thermal lamination being at least 5 0 C, preferably at least 20"C, higher than the glass transition temperature before the thermal lamination, owing to reaction of reactive 20 groups of the base polymer of the polymer layer with one another. Here, not only does reactive coupling of the layers to be laminated with one another take place; rather, there is an increase in the molecular weight and hence in the glass transition temperature due to 25 crosslinking of the polymer within the layer and between the layers. This makes delamination, splitting, even more difficult, in particular since, in the case of an attempt at manipulation, the high delamination temperatures required can, for example, irreversibly 30 damage the inks and the document is thus destroyed. Preferably, the lamination temperature with the use of such polymer materials is less than 180 0 C, preferably less than 1500C. The choice of the suitable reactive groups is possible without problems for the person 35 skilled in the art in the area of polymer chemistry. Exemplary reactive groups are selected from the group consisting of -CN, -OCN, -NCO, -NC, -SH, -S,,, -Tos, -SCN, -NCS, -H, epoxy (-CHOCH 2 ), -NH 2 , -NN+, -NN-R, -OH, WO 2009/056351 PCT/EP2008/009333 - 12 -COOH, -CHO, -COOR, -Hal (-F, -Cl, -Br, -I) , -Me-Hal (Me = at least divalent metal, for example Mg), -Si(OR) 3 , -SiHal 3 , -CH=CH 2 and -COR, where R may be any reactive or unreactive group, for example -H, -Hal, Ci 5 C 2 0-alkyl, C 3

Other reactive groups are of course 10 possible. These include the reactants of the Diels Alder reaction or a metathesis. The reactive groups can be bonded directly to the base polymer or linked via a spacer group to the base polymer. Suitable spacer groups are all spacer groups known to the person 15 skilled in the art for polymer chemistry. The spacer groups may also be oligomers or polymers which impart resilience, with the result that a danger of breaking of the security and/or valuable document is reduced. Such resilience-imparting spacer groups are known to 20 the person skilled in the art and therefore require no further description here.

Regarding further reactive 30 groups or possibilities for modification, reference is made to the literature reference "Ullmann's Encyclopaedia of Industrial Chemistry", Wiley Publishers, electronic edition 2006. In the context of the above statements, the definition of the base 35 polymer designates a polymer structure which carries no groups reactive under the lamination conditions used. These may be homopolymers or copolymers. Polymers modified compared with said polymers are also included.

WO 2009/056351 PCT/EP2008/009333 - 13 It is advantageous if polycarbonate (PC) layers are provided at least partly as polymer layers, preferably only PC layers. Polymer laminate systems which comprise 5 personalizing and/or individualizing information, in particular monolithic polymer laminate systems which will be or are produced from polymer layers of a plastics material (of a polymer), can be very readily used as security and/or valuable documents. A preferred 10 embodiment therefore envisages that the polymer laminate will be in the form of a security document or valuable document. In one embodiment, it is therefore envisaged that 15 further, relevant security elements and/or security features will be applied to and/or introduced into the substrate layers. Of course, security elements and/or security features can also be introduced between the substrate layers in the substrate layer stack prior to 20 lamination. Application to or introduction into the finished laminated polymer laminate is also possible, for example via laser engraving, etc. It is furthermore possible that one or more further 25 substrate layers consisting of nonpolymeric materials, in particular paper, will additionally be introduced into the polymer layer stack before the lamination, said one or more further substrate layers being such that it or they can no longer be detached after the 30 lamination without destruction from adjacent substrate layers and/or further adjacent substrate layers. In order to be able to embed paper layers in a polymer laminate in the stated manner, it is, for example, advantageous to provide the further paper-based 35 substrate layer with passages and/or cut-outs through which polymeric substrate layers adjacent to the paper based further substrate layer on lamination can form a bond to one another.

WO 2009/056351 PCT/EP2008/009333 - 14 Introduced diffractive structures, holograms, embossings, provision of special print elements, such as guilloches or iris print, etc., use of certain 5 colors, introduction of laser engravings, etc. may be mentioned by way of example as further security elements and/or security features. It is evident to the person skilled in the art that all security features known in the prior art can additionally be used. 10 One or more electronic circuits and/or a microchip can be introduced as a further security element into the polymer laminate. Here, the electronic circuit may be a discrete structural element, such as an inductance, a 15 capacitance, an electrical resistance, a diode, a transistor, a storage element, a display element or a combination or an interconnection of a plurality of these components, which give an oscillator, an amplifier, a microcontroller or a display. A design in 20 the form of an integrated circuit proves to be advantageous. These electronic circuits and/or microchips are frequently formed in such a way that they can be read and/or written in a noncontact manner. In order to prevent or provide security against 25 replacement or manipulation of one of the electronic circuits and/or of the microchip, one embodiment envisages applying or inserting one or more electronic circuits and/or a microchip to a first surface of a substrate layer designated as inlay layer or 30 introducing said circuits and/or said microchip into one or more cut-outs of the inlay layer and then printing one of the at least two print extracts on this first surface. Each replacement and/or removal of the microchip and/or of the one or more electronic circuits 35 also results in such a case in a change in the first personalizing and/or individualizing information and is therefore easily perceptible for a viewer.

WO 2009/056351 PCT/EP2008/009333 - 15 A further embodiment envisages that a transparent or translucent diffractive security element is directly printed at least partly during printing of one of the print extracts. A further development envisages that 5 the diffractive security element, for example a hologram, is applied to a substrate layer which is already printed with one of the print extracts and is then directly overprinted at least partly with a further print extract from among the print extracts. 10 The diffractive security element is thus optimally protected from replacement during a manipulation of a security document. The introduction of a diffractive element can therefore be effected before and/or after and/or between the printing of one or more of the 15 substrate layer surfaces. The diffractive element is therefore protected by at least partial extensive adjacency, which comprises direct printing, to at least one of the at least two print extracts from unnoticed replacement in the course of a manipulation. 20 In addition to the first individualizing and/or personalizing information, it is envisaged in some embodiments that at least one second personalizing and/or individualizing piece of information is 25 introduced into the polymer laminate or the valuable and/or security document. In one embodiment, it is envisaged for this purpose that second personalizing and/or individualizing information is divided into a plurality of further print extracts, and the plurality 30 of further print extracts is printed on a plurality of substrate layer surfaces of the plurality of substrate layers in such a way, and the substrate layers are combined in such a way to form the substrate layer stack, that the personalizing and/or individualizing 35 information is reproduced on the top of the polymer laminate and the further print extracts lie in register one on top of the other in the polymer laminate and together reproduce the second personalizing and/or WO 2009/056351 PCT/EP2008/009333 - 16 individualizing information on the bottom of the polymer laminate which is opposite the top. The application of the first personalizing information 5 can be effected in single copies or in multiple copies, in particular in double copies, on polymer layers provided in rolls or on polymer layers provided in sheets. Orientation of the individual substrate layers can be monitored by optical control methods. Use of 10 mechanical laying marks, in particular on combination of the substrate layers in the form of substrate sheets, is also usable. In an embodiment of the invention, it is envisaged that 15 a plurality of first personalizing pieces of information and/or individualizing pieces of information will be printed on the plurality of substrate layers, and the polymer laminate will be divided into a plurality of security and/or valuable 20 documents, preferably by cutting them out or punching them out. Imprinting the substrate layer surfaces with the various print extracts is effected by means of digital 25 printing processes. In particular, the at least two print extracts are printed by means of a transfer printing process or a sublimation printing process or a diffusion transfer process or a retransfer process or particularly preferably an inkjet printing process 30 and/or of a combination thereof. For inkjet printing, in particular on polycarbonate substrate layers, all inks customary in the area can in principle be used. The use of a preparation containing: 35 A) from 0.1 to 20% by weight of a binder with a polycarbonate derivative, B) from 30 to 99.9% by weight of a preferably organic solvent or solvent mixture, C) from 0 to 10% by weight of a colorant or colorant WO 2009/056351 PCT/EP2008/009333 - 17 mixture (% by weight, based on the dry mass thereof), D) from 0 to 10% by weight of a functional material or of a mixture of functional materials, E) from 0 to 30% by weight of additives and/or auxiliaries, or of a 5 mixture of such substances, the sum of the components A) to E) always being 100% by weight, as inkjet printing ink is preferred. Such polycarbonate derivatives are highly compatible with polycarbonate materials, in particular with polycarbonates based on 10 bisphenol A, such as, for example, Makrofol* films. In addition, the polycarbonate derivative used is stable to high temperatures and shows no discolorations at all at temperatures up to 200 0 C or more which are typical for lamination, with the result that the use of the 15 low-Tg materials described above is also not necessary. Specifically, the polycarbonate derivative may contain functional carbonate structural units of the formula (I) R' R' *- -O C -C- -* 0

It is preferable if R 3 and R 4 are simultaneously alkyl on one or two X atoms, in 5 particular only on one X atom. R3 and R 4 may be in particular methyl. The X atoms in the alpha-position to the diphenyl-substituted C atom (Cl) may be non dialkyl-substituted. The X atoms in the beta-position to Cl may be disubstituted by alkyl. Preferably, m is 4 10 or 5. The polycarbonate derivative may be, for example, based on monomers, such as 4,4'-(3,3,5-trimethylcyclo hexane-1,1-diyl)diphenol, 4,4'-(3,3-dimethylcyclo hexane-1,1-diyl)diphenol or 4,4'-(2,4,4-trimethylcyclo pentane-1,1-diyl)diphenol. Such a polycarbonate 15 derivative can be prepared, for example, according to the literature reference DE 38 32 396.6 from diphenols of the formula (Ia), the disclosure content of which is hereby incorporated in its entirety into the disclosure content of this description. It is possible to use both 20 a diphenol of the formula (Ia) with formation of homo polycarbonates and a plurality of diphenols of the formula (Ia) with formation of copolycarbonates (meaning of radicals, groups and parameters as in formula I). 25 R' R' HO C __OH R2 () (X)m R R R' (1a) In addition, the diphenols of the formula (Ia) may also be used as a mixture with other diphenols, for example 30 with those of the formula (Ib) WO 2009/056351 PCT/EP2008/009333 - 19 HO - Z - OH (Ib) for the preparation of high molecular weight, 5 thermoplastic, aromatic polycarbonate derivatives. Suitable other diphenols of the formula (Ib) are those in which Z is an aromatic radical having 6 to 30 C atoms, which may contain one or more aromatic nuclei, 10 may be substituted and may contain aliphatic radicals or cycloaliphatic radicals other than those of the formula (Ia) or heteroatoms as bridge members. Examples of the diphenols of the formula (Ib) are: hydroquinone, resorcinol, dihydroxybiphenyls, bis(hydroxyphenyl) 15 alkanes, bis(hydroxyphenyl)cycloalkanes, bis(hydroxy phenyl) sulfides, bis(hydroxyphenyl) ethers, bis(hydroxyphenyl) ketones, bis(hydroxyphenyl) sulfones, bis(hydroxyphenyl) sulfoxides, alpha, alpha' bis(hydroxyphenyl)diisopropylbenzenes and the compounds 20 thereof which are alkylated on the nucleus and halogenated on the nucleus. These and further suitable diphenols are described, for example, in the literature references US-A 3,028,365, 2,999,835, 3,148,172, 3,275,601, 2,991,273, 3,271,367, 3,062,781, 2,970,131 25 and 2,999,846, in the literature references 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 in their 30 entirety in the disclosure content of the present application. Examples of preferred other diphenols are: 4,4'-dihydroxybiphenyl, 2,2-bis(4-hydroxyphenyl) propane, 2,4-bis(4-hydroxyphenyl)-2-methylbutane, 1,1 bis(4-hydroxyphenyl)cyclohexane, alpha, alpha-bis(4 35 hydroxyphenyl)-p-diisopropylbenzene, 2,2-bis(3-methyl 4-hydroxyphenyl)propane, 2,2-bis(3-chloro-4-hydroxy phenyl)propane, bis(3,5-dimethyl-4-hydroxyphenyl) methane, 2,2-bis(3,5-dimethyl-4-hydroxyphenyl)propane, WO 2009/056351 PCT/EP2008/009333 - 20 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, 5 2,2-bis(3,5-dichloro-4-hydroxyphenyl)propane and 2,2 bis(3,5-dibromo-4-hydroxyphenyl)propane. Examples of particularly preferred diphenols of the formula (Ib) are: 2,2-bis(4-hydroxyphenyl)propane, 2,2-bis(3,5 dimethyl-4-hydroxyphenyl) propane, 2,2-bis(3,5-dichloro 10 4-hydroxyphenyl) propane, 2,2-bis(3,5-dibromo-4-hydroxy phenyl)propane and 1,1-bis(4-hydroxyphenyl)cyclohexane. 2,2-Bis(4-hydroxyphenyl)propane is particularly preferred. The other diphenols can be used either individually or as a mixture. The molar ratio of 15 diphenols of the formula (Ia) to the other diphenols of the formula (Ib) which are optionally to be concomitantly used should be from 100 mol% of (Ia) : 0 mol% of (Ib) to 2 mol% of (Ia) : 98 mol% (Ib), preferably from 100 mol% of (Ia) : 0 mol% of (Ib) to 20 10 mol% of (Ia) : 90 mol% of (Ib) and in particular from 100 mol% of (Ia) : 0 mol% of (Ib) to 30 mol% of (Ia) : 70 mol% of (Ib). The high molecular weight polycarbonate derivatives of the diphenols of the formula (Ia), optionally in combination with other 25 diphenols, can be prepared by the known polycarbonate preparation processes. The various diphenols can thus be linked to one another both randomly and blockwise. The polycarbonate derivatives used may be branched in a manner known per se. If branching is desired, this can 30 be achieved in a known manner by incorporation of small amounts, preferably amounts of from 0.05 to 2.0 mol% (based on diphenols used), of trifunctional compounds or compounds which are more than trifunctional, in particular those having three or more than three 35 phenolic hydroxyl groups, by condensation. Some branching agents having three or more than three phenolic hydroxyl groups are: phloroglucinol, 4,6 dimethyl-2,4,6-tri(4-hydroxyphenyl)hept-2-ene, 4,6- WO 2009/056351 PCT/EP2008/009333 - 21 dimethyl-2,4,6-tri(4-hydroxyphenyl)heptane, 1,3,5 tri(4-hydroxyphenyl)benzene, 1,1,1-tri(4-hydroxy phenyl)ethane, tri(4-hydroxyphenyl)phenylmethane, 2,2 bis[4,4-bis(4-hydroxyphenyl)cyclohexyl]propane, 2,4 5 bis (4-hydroxyphenylisopropyl)phenol, 2,6-bis(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-hydroxyphenyliso 10 propyl)phenoxy]methane and 1,4-bis[4',4"-dihydroxytri phenyl)methyl]benzene. Some of the other trifunctional compounds are 2,4-dihydroxybenzoic acid, trimesic acid, cyanuric chloride and 3,3-bis (3-methyl-4-hydroxy phenyl)-2-oxo-2,3-dihydroindole. Monofunctional 15 compounds in customary concentrates serve as chain stoppers for regulation, known per se, of the molecular weight of the polycarbonate derivatives. Suitable compounds are, for example, phenol, tert-butylphenols or other alkyl-substitued phenols. In particular, small 20 amounts of phenols of the formula (Ic) HO R (IC) in which R is a branched C 8 - and/or C 9 -alkyl radical, 25 are suitable for regulating the molecular weight. In the alkyl radical R, the proportion of CH 3 protons is preferably from 47% to 89% and the proportion of CH and

CH

2 protons from 53% to 11%; likewise preferably, R is in the o- and/or p-position to the OH group and 30 particularly preferably the upper limit of the ortho fraction is 20%. The chain stoppers are generally used in amounts of from 0.5 to 10, preferably from 1.5 to 8, mol%, based on diphenols used. Polycarbonate WO 2009/056351 PCT/EP2008/009333 - 22 derivatives can preferably be prepared according to the phase boundary behavior (cf. H. Schnell "Chemistry and Physics of Polycarbonates", Polymer Reviews, Vol. IX, page 33 et seq., Interscience Publ. 1964) in a manner 5 known per se. Here, the diphenols of the formula (Ia) are dissolved in the 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 10 used. Chain stoppers, for example of the formula (Ic), can be added for regulating the molecular weight. Reaction is then effected in the presence of an inert, preferably polycarbonate-dissolving, organic phase with phosgene by the phase boundary condensation method. The 15 reaction temperature is from 0 0 C to 40'C. The optionally concomitantly used branching agents (preferably from 0.05 to 2.0 mol%) can either be initially introduced with the diphenols in the aqueous alkaline phase or dissolved in the organic solvent and 20 added before phosgenation. In addition to the diphenols of the formula (Ia) and optionally other diphenols (Ib), the mono- and/or bischlorocarbonic acid esters thereof may also be concomitantly used, these being added in solution in organic solvents. The amount of 25 chain stoppers 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 acid esters, the amount of phosgene can be reduced accordingly in a 30 known manner. Suitable organic solvents for the chain stoppers and optionally for the branching agents and the chlorocarbonic acid esters are, for example, methylene chloride, chlorobenzene and in particular mixtures of methylene chloride and chlorobenzene. 35 Optionally, the chain stoppers 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 WO 2009/056351 PCT/EP2008/009333 - 23 organic phase for the phase boundary polycondensation. For example, NaOH solution serves as the aqueous alkaline phase. The preparation of the polycarbonate derivatives by the phase boundary process can be 5 catalyzed in a customary 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 from 0.05 to 10 mol%, based on moles of diphenols used. The 10 catalysts can be added before the beginning of phosgenation or during or even after the phosgenation. The polycarbonate derivatives can be prepared by the known process in the homogeneous phase, the so-called "pyridine process", and by the known melt 15 transesterification process with the use of, for example, diphenyl carbonate instead of phosgene. The polycarbonate derivatives may be straight-chain or branched; they are homopolycarbonates or copolycarbonates based on diphenols of the formula 20 (Ia). Because of the arbitrary composition of other diphenols, in particular with those of the formula (Ib), the polycarbonate properties may vary in an advantageous manner. In such copolycarbonates, the diphenols of the formula (Ia) are present in the 25 polycarbonate derivatives 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. The polycarbonate derivative may be a 30 copolymer containing, in particular consisting of, monomer units Ml based on the formula (Ib), preferably bisphenol A, and monomer units M2 based on the germinally disubstituted dihydroxydiphenylcycloalkane, preferably 4,4'-(3,3,5-trimethylcyclohexane-1,1 35 diyl)diphenol, the molar ratio M2/Ml preferably being greater than 0.3, in particular greater than 0.4, for example greater than 0.5. It is preferable if the polycarbonate derivative has an average molecular WO 2009/056351 PCT/EP2008/009333 - 24 weight (weight average) of at least 10 000, preferably from 20 000 to 300 000. The component B can in principle be substantially 5 organic or aqueous. Substantially aqueous means that up to 20% by weight of the component B) may be organic solvent. Substantially organic means that up to 5% by weight of water may be present in the component B) Preferably, the component B contains or consists of a 10 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. In particular, aliphatic, cycloaliphatic, aromatic 15 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, are suitable. Mesitylene, 1,2,4 20 trimethylbenzene, cumene and solvent naphtha, toluene, xylene, methyl acetate, ethyl acetate, methoxypropyl acetate, ethyl 3-ethoxypropionate are preferred. The following are very particularly preferred: mesitylene (1,3,5-trimethylbenzene), 1,2,4-trimethylbenzene, 25 cumene (2-phenylpropane), solvent naphtha and ethyl 3-ethoxypropionate. A suitable solvent mixture comprises, for example, Li) from 0 to 10% by weight, preferably from 1 to 5% by weight, in particular from 2 to 3% by weight, of mesitylene, L2) from 10 to 50% by 30 weight, preferably from 25 to 50% by weight, in particular from 30 to 40% by weight, of 1-methoxy-2 propanol acetate, L3) from 0 to 20% by weight, preferably from 1 to 20% by weight, in particular from 7 to 15% by weight, of 1,2,4-trimethylbenzene, L4) from 35 10 to 50% by weight, preferably from 25 to 50% by weight, in particular from 30 to 40% by weight, of ethyl 3-ethoxypropionate, L5) from 0 to 10% by weight, preferably from 0.01 to 2% by weight, in particular WO 2009/056351 PCT/EP2008/009333 - 25 from 0.05 to 0.5% by weight, of cumene and L6) from 0 to 80% by weight, preferably from 1 to 40% by weight, in particular from 15 to 25% by weight, of solvent naphtha, the sum of the components Li to L6 always 5 being 100% by weight. The polycarbonate derivative typically has an average molecular weight (weight average) of at least 10 000, preferably from 20 000 to 300 000. 10 In detail, the preparation may contain: A) from 0.1 to 10% by weight, in particular from 0.5 to 5% by weight, of a binder with a polycarbonate derivative based on a geminally disubstituted dihydroxydiphenylcycloalkane, B) from 40 to 99.9% by weight, in particular from 45 to 15 99.5% by weight, of an organic solvent or solvent mixture, C) from 0.1 to 6% by weight, in particular from 0.5 to 4% by weight, of a colorant or colorant mixture, D) from 0.001 to 6% by weight, in particular from 0.1 to 4% by weight, of a functional material or 20 of a mixture of functional materials, E) from 0.1 to 30% by weight, in particular from 1 to 20% by weight, of additives and/or auxiliaries, or of a mixture of such substances. 25 In principle, any desired colorant or colorant mixture is suitable as component C, if a colorant is to be provided. Colorants are all color-imparting substances. This means that they may be both dyes (an overview of dyes is given in Ullmann's Encyclopedia of Industrial 30 Chemistry, Electronic Release 2007, Wiley Publishers, Chapter "Dyes, General Survey") and pigments (an overview of organic as well as inorganic pigments is given in Ullmann's Encyclopedia of Industrial Chemistry, Electronic Release 2007, Wiley Publishers, 35 Chapter "Pigments, Organic" and "Pigments, Inorganic) Dyes should be soluble or dispersible (in a stable manner) or suspendable in the solvents of component B. Furthermore, it is advantageous if the colorant is WO 2009/056351 PCT/EP2008/009333 - 26 stable, in particular color-stable, at temperatures of 160*C or more for a period of more than 5 min. It is also possible for the colorant to be subjected to a specified and reproducible color change under the 5 processing conditions and is chosen accordingly. In addition to having thermal stability, pigments must in particular be present in very fine particle size distribution. In inkjet printing in practice, this means that the particle size should not be above 10 1.0 pm, since otherwise blockages in the printing head are the result. As a rule, nanoscale solid-state pigments and dissolved dyes have proven useful. The colorant may be cationic, anionic or neutral. The following may be mentioned merely as examples of 15 colorants which can be used in inkjet printing: Brilliant Black C.I. No. 28440, Chromogen Black C.I. No. 14645, Direct Deep Black E C.I. No. 30235, Fast Black Salt B C.I. No. 37245, Fast Black Salt K C.I. No. 37190, Sudan Black HB C.I. No. 26150, Naphthol 20 Black C.I. No. 20470, Bayscript* Black liquid, C.I. Basic Black 11, C.I. Basic Blue 154, Cartasol* Turquoise K-ZL liquid, Cartasol* Turquoise K-RL liquid (C.I. Basic Blue 140), Cartasol Blue K5R liquid. For example, the commercially available dyes Hostafine" 25 Black TS liquid (marketed by Clariant GmbH, Germany), Bayscript* Black liquid (C.I. mixture, marketed by Bayer AG, Germany), Cartasol® Black MG liquid (C.I. Basic Black 11, registered trademark of Clariant GmbH, Germany), Flexonylschwarz* PR 100 (E C.I. No. 30235, 30 marketed by Hoechst AG), Rhodamine B, Cartasol* Orange K3 GL, Cartasol* Yellow K4 GL, Cartasol" K GL, or Cartasol* Red K-3B are furthermore suitable. Furthermore, anthraquinone, azo, quinophthalone, coumarin, methine, perinone and/or pyrazole dyes, for 35 example available under the trade name Macrolex*, can be used as soluble colorants. Further suitable colorants are described in the literature reference Ullmann's Encyclopedia of Industrial Chemistry, WO 2009/056351 PCT/EP2008/009333 - 27 Electronic Release 2007, Wiley Publishers, Chapter "Colorants Used in Ink Jet Inks". Readily soluble colorants lead to optimal integration into the matrix and the binder of the print layer. The colorants can be 5 added either directly as dye or pigment or as paste, a mixture of dye and pigment together with a further binder. This addition of binder should be chemically compatible with the further components of the preparation. If such a paste is used as a colorant, the 10 stated amount of component B is based on the colorant without the other components of the paste. These other components of the paste are then to be subsumed under the component E. With the use of so-called colored pigments in the scale colors cyan-magenta-yellow and 15 preferably also (carbon) black, solid color images are possible. The component D comprises substances which are directly visible to the human eye with the use of technical aids 20 or are visible by using suitable detectors. Here, the relevant materials known to the person skilled in the art (cf. also van Renesse, Optical document security, 3 rd Ed., Artech House, 2005) are meant, which are used for protecting valuable and security documents. These 25 include luminescent substances (dyes or pigments, organic or inorganic), such as, for example, photo luminophores, electroluminophores, antistokes luminophores, fluorophores, but also magnetizable, photoacoustically addressable or piezoelectric 30 materials. Furthermore, Raman-active or Raman-enhancing materials can be used, as can so-called barcode materials. Here too, either the solubility in the component B or, in the case of pigmented systems, particle sizes of < 1 pm and a thermal stability for 35 temperatures > 160 0 C are considered to be preferred criteria in the context of the statements for component C. Functional materials can be added directly or via a paste, i.e. to a mixture with a further binder, which WO 2009/056351 PCT/EP2008/009333 - 28 then forms a constituent of the component E, or to the binder of component A which is used. In the case of inks for an inkjet print, the component 5 E usually comprises prepared substances, such as antifoams, adjusting agents, wetting agents, surfactants, flow agents, drying agents, catalysts, (light) stabilizers, preservatives, biocides, surfactants, organic polymers for viscosity adjustment, 10 buffer systems, etc. Suitable adjusting agents are adjusting salts customary in the field. An example of this is sodium lactate. Suitable biocides are all commercially available preservatives which are used for inks. Examples of these are Proxel*GXL and Parmetol* 15 A26. Suitable surfactants are all commercially available surfactants which are used for inks. Amphoteric or nonionic surfactants are preferred. However, it is of course also possible to use specific anionic or cationic surfactants which do not change the 20 properties of the dye. Examples of suitable surfactants are betaines, ethoxylated diols, etc. Examples are the product series Surfynol* and Tergitol*. Particularly when used for inkjet printing, the amount of surfactants is chosen, for example, with the proviso 25 that the surface tension of the ink is in the range from 10 to 60 mN/m, preferably from 20 to 45 mN/m, measured at 25'C. It is possible to prepare a buffer system which stabilizes the pH in the range from 2.5 to 8.5, in particular in the range from 5 to 8. Suitable 30 buffer systems are lithium acetate, borate buffer, triethanolamine or acetic acid/sodium acetate. A buffer system is suitable in particular in the case of a substantially aqueous component B. For adjusting the viscosity of the ink, (optionally water-soluble) 35 polymers can be provided. All polymers suitable for customary ink formulations are suitable here. Examples are water-soluble starch, in particular having an average molecular weight of from 3000 to 7000, WO 2009/056351 PCT/EP2008/009333 - 29 polyvinylpyrrolidone, in particular having an average molecular weight of from 25 000 to 250 000, polyvinyl alcohol, in particular having an average molecular weight of from 10 000 to 20 000, xanthan gum, carboxy 5 methylcellulose, ethylene oxide/propylene oxide block copolymer, in particular having an average molecular weight of from 1000 to 8000. An example of the last mentioned block copolymer is the product series Pluronic*. The proportion of biocide, based on the 10 total amount of ink, may be in the range from 0 to 0.5% by weight, preferably from 0.1 to 0.3% by weight. The proportion of surfactant, based on the total amount of ink, may be in the range from 0 to 0.2% by weight. The proportion of adjusting agents may be, based on the 15 total amount of ink, from 0 to 1% by weight, preferably from 0.1 to 0.5% by weight. The auxiliaries also include other components, such as, for example, acetic acid, formic acid or N-methylpyrrolidone, or other polymers from the dye solution or paste used. Regarding 20 substances which are suitable as component E, reference is additionally made, for example, to Ullmann's Encyclopedia of Chemical Industry, Electronic Release 2007, Wiley Publishers, Chapter "Paints and Coatings", Section "Paint Additives". 25 The features of the polymer laminate according to the invention and/or of a valuable and/or security document have the same advantages as the corresponding features of the production method according to the invention. A 30 distribution of the first personalizing and/or individualizing information and optionally one or more further second personalizing and/or individualizing pieces of information in different planes of the polymer laminate or valuable and/or security document 35 gives a security feature which offers very high protection from forgery. High protection from forgery also exists with respect to imitation since high resolution in-register printing of the first Wo 2009/056351 PCT/EP2008/009333 - 30 personalizing and/or individualizing information which, for example, comprises a colored facial image is to be realized only with very high technical complexity if the colored information is distributed over different 5 planes of the polymer laminate or of the valuable and/or security document. With the use of an ink which is prepared on the basis of polycarbonate and of substrate layers which are likewise prepared on the basis of polycarbonate, a monolithic body in which 10 transitions of the substrate layers used in the production are no longer recognizable results after lamination. The imprinted color, too, is then completely integrated into the monolithic body, i.e. the monolithic polymer laminate. As a result, large 15 area printing with the first personalizing and/or individualizing information can be effected without any danger of delamination, as exists for the use of other inks and/or printing inks. Particularly in the case of destructive test methods for determining the 20 authenticity of a valuable and/or security document, a security feature formed in this manner can be reliably recognized. Nondestructive test methods in which a distance of the individual print extracts from a surface of the polymer laminate or valuable and/or 25 security document are determined, can likewise be used for verifying the novel security feature. Compared with methods which provide full-color application of a first information part in a print layer and addition of black information parts by means of laser engraving, the 30 invention described has the advantage that application of the first personalizing and/or individualizing information by printing can be effected with high resolution, for example, using inkjet printing, on the different substrate layer surfaces and it is therefore 35 possible by a standard and simple, very well controlled printing technique. Additional provision of a laser engraving is therefore not necessary in the method but of course is possible as an additional security WO 2009/056351 PCT/EP2008/009333 - 31 feature. A production method as a whole is therefore simplified. Furthermore, three-dimensional optical effects can be 5 realized with the invention on suitable division of the first information. Preferred embodiments are explained in more detail below with reference to a drawing. Here: 10 fig. 1 shows a schematic apparatus for producing a security and/or valuable document in the form of a polymer laminate; 15 fig. 2 shows a schematic diagram of a structure of a security and/or valuable document in the form of a polymer laminate; fig. 3a-3c show further schematic diagrams for 20 explaining the production of a security and/or valuable document in the form of a polymer laminate; fig. 4 shows a further schematic diagram of a 25 further polymer laminate personalized in a multilayer manner; fig. 5 shows a schematic diagram of a structure of a valuable and/or security document in the form 30 of a polymer laminate and having a first and second personalizing and/or individualizing information; fig. 6 shows a schematic diagram of a further 35 security and/or valuable document in the form of a polymer laminate and having an integrated chip; WO 2009/056351 PCT/EP2008/009333 - 32 fig. 7 shows a schematic diagram of a polymer laminate in which a diffractive element is also incorporated. 5 Fig. 1 is intended to explain, by way of example, a method for producing a valuable and/or security document which is in the form of a polymer laminate. Fig. 1 shows an apparatus for producing a polymer laminate. The apparatus comprises a plurality of 10 rollers on which polymer films, preferably polycarbonate films, are wound. For producing a polymer laminate, at least three polymer layers are required as substrate layers. These are arranged on rollers 2-4. Optionally, one or more further polymer layers, in 15 particular from 1 to 12, particularly preferably from 2 to 10 and particularly preferably from 4 to 6 polymer layers, can be supplied on rollers. These possible additional polymer layers which are available as a substrate are represented via the roller 5, which is 20 shown by a dashed line. The polymer layers 6-9 provided or supplied by rollers 2-5 have thicknesses of from 5 pm to 350 pm, preferably thicknesses of from 50 pm to 150 pm. The individual polymer layers 6-9 may all have the same thickness or different thicknesses. 25 A control unit 10 preferably in the form of a computer is supplied with first personalizing information, for example in the form of a computer data record. The first personalizing and/or individualizing information 30 may comprise, for example, a colored facial image (passport photo) and personal data, such as surname, first name, date of birth, place of residence, place of birth, street, house number, zip code, etc. The control unit 10 is formed in such a way that it divides the 35 first personalizing and/or individualizing information into at least two print extracts which each comprise partial information of the first personalizing and/or individualizing information. For example, three WO 2009/056351 PCT/EP2008/009333 - 33 monochrome color separations in a cyan-magenta-yellow color space or color system are created from the colored facial image. In addition, a fourth color separation for black and/or gray image constituents can 5 be created. The at least two color print separations, which, for example, are identical to the monochrome color separations or represent a combination of two monochrome color separations, are transmitted to printing units 11-14. These printing units 11-14 are in 10 the form of digital printing units, which means that they perform a digital printing process. Preferably, the printing units 11-14 are in the form of inkjet printing units. In some embodiments, the various printing units 11-14 may also print according to 15 different digital printing processes. In an embodiment in which only the three polymer layers 6-8 are provided from rollers 2-4, for example, two print extracts are printed in register via the printing 20 units 11 and 12 on opposite surfaces of the polymer layer 7. This means that, for example, a print extract which is a combination of a yellow and magenta-colored monochromatic color separation of the first personalizing and/or individualizing information is 25 printed on the substrate layer which is provided by the polymer layer 7, on a top 15, i.e. an upper substrate layer surface, via the printing unit 11. The second print extract which is a combination of a black color separation and a cyan-colored color separation is 30 printed in register with the first print extract on a bottom 16 (a lower substrate layer surface) of the substrate layer provided by the polymer layer 7, by the printing unit 12. 35 In another embodiment, the printing units 11-14 may each print out a monochromatic color separation of a three color-black color system, the black color separation here likewise being regarded as a WO 2009/056351 PCT/EP2008/009333 - 34 monochromatic color print. This means that the printing units 13 and 14 likewise print two different print extracts in register on the polymer layer 9. In such a case, it is advantageous if a yet further transparent 5 polymer layer is inserted (not shown) between the polymer layers 7 and 9 so that the print extracts printed by the printing units 12 and 13 are a distance apart in the finished polymer laminate. However, this is not absolutely essential. In other embodiments, 10 printing on the inner substrate layer surfaces of the outer substrate layers (polymer layers) can also be provided. The polymer layers 6-8 or 6-9 are guided via deflection 15 rollers 17 and combined to form a polymer layer stack or substrate layer stack 18. The combination or uniting of the individual polymer layers 6-9 is effected, at least if the at least two print extracts are printed on different substrates or polymer layers 6-9 and these 20 have the same expansion and/or shrinkage properties during lamination, in such a way that the individual print extracts, i.e. the printed print extracts, are arranged in register one on top of the other in the substrate layer stack 18. 25 The substrate layers or polymer layers 6-8 or 6-9 are then combined to form a laminate. The joining is effected by a lamination method, which is preferably carried out by a hot and cold press 19. The substrate 30 layers or polymer layers 6-8 or 6-9 bonded to one another are fed to an isolating unit 20, which, for example, is in the form of a punch and, for example, punches out and/or cuts out a security and/or valuable document 21 which is a polymer laminate. 35 It is self-evident to the person skilled in the art that the production method is described here in greatly simplified form. Of course, further steps of the method WO 2009/056351 PCT/EP2008/009333 - 35 and parts of the apparatus, which are intended for introducing further security elements and/or security features for a security and/or valuable document, can be inserted and/or added. For example, a laser 5 engraving station can be provided and/or a hologram in the form of a further layer, preferably a developed photosensitive polymer layer, can be added before the lamination. In particular, even further, nondigital printing processes can also be used in order, for 10 example, to apply guilloches or classical offset print or OVI colors via screenprinting, luminescent colors, etc. There are optionally also drying stations for these printing inks, such as UV fixing, etc. 15 In the production process described in relation to fig. 1, the individual substrate layers are supplied in the form of polymer layers provided on rollers. In another embodiment of the method, the individual polymer layers or substrate layers can be printed 20 and/or combined in the form of sheets. In-register orientation is preferably effected via so-called three point laying of the individual combined sheets. Before the lamination process, in which the individual polymer layers are joined to form a laminate, attachment, for 25 example via ultrasonic bonding and/or targeted introduction of laser radiation, can be effected locally at one or more points in individual boundary layers of substrate layers adjacent to one another. Other attachment methods, for example via heated clips, 30 can of course also be used. An isolating step can be dispensed with if the sheets are adapted in register to the polymer laminate to be produced. Fig. 2 shows, once again schematically, the structure 35 of a valuable and/or security document 21 in the form of a polymer laminate. Here, by way of illustration, the individual substrate layers 22, 23, 24 are shown a distance apart. In the finished valuable and/or WO 2009/056351 PCT/EP2008/009333 - 36 security document 21, these layers are preferably bonded to one another monolithically by material bonding. An upper substrate layer surface 25 of the substrate layer 23 is printed with a print extract 5 which comprises the monochromatic color separations of the colors yellow and magenta. A lower substrate layer surface 26 of the substrate layer 23 is correspondingly printed with a second print extract which comprises the monochromatic color separations for the colors cyan and 10 black. In order to protect the imprinted personalizing and/or individualizing partial information of the two print extracts from manipulation and/or forgery, the substrate layers 22 and 24 are provided on the outside. In the finished polymer laminate, the two print 15 extracts are arranged or imprinted in different planes of the security and/or valuable document 21. Fig. 3a-c is intended to explain, by way of example, how first information comprising a colored facial image 20 is introduced, according to a further embodiment, into a polymer laminate. Fig. 3a schematically shows the first information 31 representing a facial image. Coordinated with the individual constituents of the facial image via a letter is in each case the 25 corresponding color which this constituent has. Let an outer contour 32 be black (s), a nose 33 be yellow (g), a mouth 34 be magenta-colored (m) and eyes 35 cyan colored (c). 30 The individual color separations, i.e. the individual elements of the schematically shown facial image, are in each case individual print extracts 36-39 which in each case are printed on a top of different substrate layers 41-44, as shown in fig. 3b. In addition, a 35 substrate 40 arranged so as to be the lowermost substrate is printed, for example, with a background motif which comprises, for example, guilloche lines 46. The individual printed substrate layers 41-44 are WO 2009/056351 PCT/EP2008/009333 - 37 combined in register one on top of the other to form a substrate layer stack. In addition, a further substrate layer 45 is arranged above the substrate layer 44 and is transparent like substrate layers 41-44. Finally, 5 fig. 3c shows the plan view of security document 47 after the individual substrate layers 40-45 have been united by means of lamination to form the polymer laminate. It is clearly evident that the individual print extracts together reproduce the first 10 information, as shown in fig. 3a. In a further embodiment similar to that according to fig. 3a-3c, the first information which comprises an image of a three-dimensional object is divided into 15 print extracts in a manner such that the print extracts each comprise the pixels of a depth region or of a distance zone of the pixels of the real object from a viewer. In other words, the pixels of the three dimensional object which map those object contours of a 20 first distance region which are closest to the viewer are assigned to one print extract. The pixels which represent the object contours and surfaces or an adjacent distance region are assigned to a further print extract. The procedure is continued in this 25 manner until the pixels which map the most remote object points are also assigned to a print extract. It is evident to the person skilled in the art that the distance regions are chosen so that a corresponding desired number of print extracts is obtained. 30 Preferably, from 2 to 9, particularly preferably from 3 to 5, print extracts are used. Print extracts are printed on substrate layer surfaces, preferably in color, i.e. by means of a plurality of inks per print extract on different substrate layer surfaces, and are 35 combined in such a way that the print extract which comprises the pixels which map the object points closest to the viewer is printed on the lowermost substrate layer surface and the print extract which WO 2009/056351 PCT/EP2008/009333 - 38 represents the object points furthest away from the viewer is printed on the uppermost of the printed substrate layer surfaces. The print extracts are, so to speak, introduced into the substrate laminate in 5 "inverted" form with respect to a distance of the object points shown, based on a viewed upper surface of the produced substrate layer stack or substrate laminate. As a result, the effect is achieved that the three-dimensional object appears to emerge from the 10 laminate. The reason for this is that the human brain inverts back at least a known object, for example a face. If the nose were to be printed on the lowermost substrate layer surface, the mouth and the eyes in this order on the substrate layer surfaces arranged above 15 this and the ears on the uppermost substrate layer surface, the face would, for a human viewer, apparently emerge forward from the uppermost printed substrate layer surface. 20 Fig. 4 shows a diagram similar to that according to fig. 3b. An antenna structure 52 to which a microchip 53 is connected is imprinted on a first substrate layer 51. After the imprinting of the antenna structure and the application of the microchip 53, this first 25 substrate layer 51 is printed with a first print extract 54 (e.g. black) of first information which comprises a facial image. The substrate layers 55-57 arranged thereon in the polymer laminate are printed with further print extracts 58-60 (e.g. cyan-magenta 30 yellow), which in each case comprise partial information of the first information, i.e. of the facial image. In the embodiment described, the substrate layers 55-57 are formed so that they each comprise a transparent region 61 in which the 35 corresponding print extracts 58-60 are imprinted. The other surface regions 62 of the substrate layers 55-57 are printed as a solid area in this embodiment. This printing can also be carried out by a nondigital WO 2009/056351 PCT/EP2008/009333 - 39 printing process, for example by offset printing or indirect letterset. Preferably, a polycarbonate-based ink identical or similar to the preparation described above is used in order to prevent possible 5 delamination, which exists with the use of other printing inks. Prior to lamination, the first substrate layer 51 and the other substrate layers 55-57 are combined in 10 register together with a transparent substrate layer 63 and bonded to give a polymer laminate. In addition, further substrate layers on the substrate layer surfaces of which, for example, a second personalizing and/or individualizing information, preferably 15 differing from the first personalizing and/or individualizing information and likewise preferably colored, divided into a plurality of further print extracts which in each case comprise partial information of the second personalizing and/or 20 individualizing information, is imprinted can be arranged below the first substrate layer which is preferably opaque. Figs. 5 and 6 schematically show further structures of 25 valuable and/or security documents in the form of a polymer laminate. Fig. 5 shows a valuable and/or security document 71 which comprises a polymer laminate which is produced from nine substrate layers 72-80, which are polymer layers, for example all polycarbonate 30 layers. A middle substrate layer 76 is opaque and preferably printed over the whole area optionally both on a top 81 and on a bottom 82. The substrate layers 73 and 75 are each printed on their corresponding tops and bottoms in each case with one of four different print 35 extracts of first personalizing and/or individualizing information, the colors with which the individual print extracts are printed being indicated by the letters c for cyan, m for magenta, g for yellow and s for black.

WO 2009/056351 PCT/EP2008/009333 - 40 Analogously, the substrate layers 77 and 79 are printed on their tops and bottoms with different print extracts of second individualizing and/or personalizing information. The individual colors are accordingly 5 likewise identified by letters. The subsequent Arabic numerals indicate in each case that the corresponding layer comprises partial information of the first information (1) or of the second information (2). The intermediate spaces shown are again merely inserted for 10 illustration of the production method. In the finished state, transitions between the originally present substrate layers are no longer observable. Only the print extracts indicate where substrate layer surfaces were formally present before joining. 15 Analogously to the diagram according to fig. 5, fig. 6 shows a further embodiment of a valuable and/or security document which is a polymer laminate. In this embodiment of a valuable and/or security document 91, 20 an electronic circuit 92 is inserted into a central substrate layer 93. Analogously to the structure of the valuable and/or security document 71 according to fig. 5, the substrate layers 94 and 96 of the substrate layers 94-97, which are arranged above the substrate 25 layer 93, are printed with print extracts of first personalizing and/or individualizing information on their substrate layer surfaces. Below the substrate layer 93, three further substrate layers 98-100 are arranged. In this embodiment, a first print extract of 30 second individualizing and/or personalizing information in the form of a monochromatic color separation, for example of the color magenta, is imprinted directly onto the electronic circuit 92 and a lower substrate layer surface 101. The substrate layer 99 is printed on 35 its substrate layer surfaces with a cyan-colored color separation and a yellow-colored further monochromatic color separation. A lower substrate layer surface 102 of the substrate layer 99 can be printed with a black WO 2009/056351 PCT/EP2008/009333 - 41 print extract in addition to the yellow monochromatic color separation. Fig. 7 schematically shows, in a sectional view, a 5 further embodiment of a security document 110 in the form of a polymer laminate. The polymer laminate comprises transparent substrate layers 111-114. First, a print extract of the first personalizing and/or individualizing information, for example a black print 10 extract 116, is printed on the lowermost substrate layer 111. Thereafter, a diffractive security element 115 (for example a transparent Kinegram") is arranged thereon. Thereafter, a further, for example magenta-colored, print extract 117 of the first personalizing and/or 15 individualizing information is printed directly on the diffractive security element 115 so that the diffractive security element 115 is at least partly imprinted. The further print extracts 118 (e.g. yellow) and 119 (e.g. cyan) of the first personalizing and/or individualizing 20 information are printed, for example, on the substrate layers 112 and 113. The substrate layers 111-113, as shown in fig. 7, are combined together with an uppermost substrate layer 114, which acts as a protective layer, oriented and joined to form the polymer laminate by 25 means of lamination in a hot-cool press. The diffractive security element 115 is better protected from unauthorized replacement and/or manipulation. In other embodiments, the diffractive element is 30 applied to one of the substrate layer surfaces after this substrate layer surface has been printed with one of the print extracts. In yet another embodiment, the diffractive element is 35 first introduced on or into a substrate layer surface, which is then printed with one of the at least two print extracts. The diffractive element can be introduced, for example, by means of hot stamping.

WO 2009/056351 PCT/EP2008/009333 - 42 Other advantageous embodiments are those in which the diffractive element is arranged between two substrate layer surfaces, both of which are printed in each case 5 with one of the at least two print extracts. In the embodiments described, the different print extracts are described as color separations of the first information. The first information, which, for 10 example, may also comprise personalizing and/or individualizing alphanumeric character strings or a pattern, image, etc., can, however, also be divided in another manner into print extracts so that the individual print extracts are multicolored or colored. 15 Purely formally, such print extracts could of course be divided into a plurality of monochrome "sub-print extracts", all of which are then printed on the same substrate layer surface, preferably in one operation. 20 In the embodiments described, the individual print extracts are preferably applied by means of inkjet printing. The substrate layers are preferably polycarbonate-based 25 polymer layers. The ink used is preferably a liquid preparation which is likewise prepared on the basis of polycarbonate. This makes it possible to produce highly stable monolithic polymer laminates which are particularly manipulation-proof. 30 Below, examples for the preparation of a polycarbonate derivative which can be used according to the invention, a production of a liquid preparation suitable for the production of an inkjet printing ink, 35 and production of a first inkjet printing ink which can be used according to the invention are given.

WO 2009/056351 PCT/EP2008/009333 - 43 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-hydroxy 5 phenyl)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. A solution of 1.88 g of phenol in 2500 ml of methylene chloride is then added. 10 198 g (2 mol) of phosgene were passed into the thoroughly stirred solution at pH 13 to 14 and 21 to 25 0 C. Thereafter, 1 ml of ethylpiperidine is added and stirring is effected for a further 45 min. The bisphenolate-free aqueous phase is separated off and the organic phase is 15 washed neutral with water after acidification with phosphoric acid and is freed from the solvent. The polycarbonate derivative had a relative solution viscosity of 1.263. The glass transition temperature 20 was determined as 183 0 C (DSC). Example 2: Production of a liquid preparation suitable for the production of an inkjet printing ink 25 A liquid preparation was produced from 17.5 parts by weight of the polycarbonate derivative from example 1 and 82.5 parts by weight of a solvent mixture according to table I. 30 Table I Mesitylene 2.4 1-Methoxy-2-propanol acetate 34.95 1,2,4-Trimethylbenzene 10.75 Ethyl 3-ethoxypropionate 33.35 Cumene 0.105 Solvent naphtha 18.45 WO 2009/056351 PCT/EP2008/009333 - 44 A colorless, highly viscous solution having a solution viscosity of 800 mPa-s at room temperature was obtained. 5 Example 3: Production of a first inkjet printing ink which can be used according to the invention 10 g of polycarbonate solution from example 2 and 10 32.5 g of the solvent mixture from example 2 were homogenized with a magnetic stirrer in a 50 ml wide necked glass vessel having a thread (4% strength PC solution). A colorless, low-viscosity solution having a solution viscosity of 5.02 mPa-s at 20 0 C was obtained. 15 About 2% of pigment black 28 was also added to the polycarbonate solution obtained. The result is an ink by means of which black/white images can be printed on polycarbonate films. Monochrome and/or colored inks can 20 be produced in a corresponding manner by an equivalent addition of other pigments or dyes. There is virtually no change in the resolution of a pixel pattern, printed with the ink, in the joining 25 process in which the polycarbonate substrate layer printed with the pixel pattern is bonded to a polycarbonate substrate layer arranged thereon. This means that the pixel pattern is retained in virtually the same resolution even after the lamination. 30 An optical investigation of the laminate otherwise showed no detectable phase boundary at all. The laminate appeared as a monolithic block which also withstands delamination in an outstanding manner. 35 WO 2009/056351 PCT/EP2008/009333 - 45 List of reference numerals 1 Apparatus for producing a polymer laminate 2-5 Rollers 5 6-9 Polymer layers 10 Control unit 11-14 Printing units 15 Top 16 Bottom 10 17 Deflection rollers 18 Substrate layer stack 19 Hot and cold press 20 Isolating unit 21 Security and/or valuable document 15 22-24 Substrate layers 25 Upper substrate layer surface 26 Lower substrate layer surface 31 first information 32 Outer contour 20 33 Nose 34 Mouth 35 Eyes 36-39 Print extracts 40-45 Substrates 25 46 Guilloche lines 47 Security document 51 first substrate layer 52 Antenna structure 53 Microchip 30 54 first print extract 55-57 Substrate layers 58-60 further print extracts 61 transparent region 62 other surface region 35 63 transparent substrate layer 71 valuable and/or security document 72-80 Substrate layers 81 Top WO 2009/056351 PCT/EP2008/009333 - 46 82 Bottom 91 Valuable and/or security document 92 Electronic circuit 93-100 Substrate layers 5 101 Substrate layer surface 102 Substrate layer surface 110 Security document 111-114 Substrate layers 115 Diffractive security element 10 116-119 Print extracts
