Description

Field of the invention

The invention relates to a method for producing a security and / or value document comprising a polymer layer composite or consisting thereof, wherein the polymer layer composite is formed from a polymer layer subassembly and a polymer cover layer and wherein the polymer layer subassembly and / or the polymer cover layer contains a laser-sensitive component, with the following method steps A) first information is applied to the polymer layer subassembly by means of an inkjet printing process as a colored inkjet printing layer, B) the polymer cover layer is applied to the inkjet printing layer and joined to the polymer layer subassembly. The invention further relates to a security and / or value document that can be produced by means of such a method.

Prior art and background of the invention.

Personalization of a security and / or value document is a process in which personalized information, ie for a specific person who is designated as the holder of the security and / or value document, individual information, for example image information, such as a passport photograph, fingerprint, etc., strings, such as name, address, place of residence, etc., are affixed to or in the relevant security and / or valuable document. This can be done for example in the form of colored or black-and-white imprints or laser engraving. Alternatively or additionally, these or other person-specific information may also be stored in an electronic circuit integrated in the security and / or value document, in which case the electronic circuit or the information contained therein may be read out by authorized persons. Furthermore, other electronic components for storing and displaying information can also be integrated in the document, for example a display module.

Personalization can be done centrally or remotely. In the case of centralized personalization, the personalized information is collected and transmitted to a manufacturer of the security and / or value document. This then brings the personalized information in or on the security and / or value document in the course of its production and completion. In the case of decentralized personalization, a manufacturer of the security and / or value document supplies a non-personalized blank to one or more personalization points located remotely by the manufacturer, which performs the collection of the personalized information and then attaches it to the blank itself and so on the security and / or Value document, possibly supplemented by final attachment of a top protective film, finished. In addition, there is the possibility of a semi-centralized personalization where the manufacturer delivers the non-personalized blanks to one or more of the manufacturer's remote personalization locations, which receives the personalized information from the capture points that are physically remote from the manufacturer and / or the personalization points, and the personalized security and / or or value documents.

From the literature DE 2 907 004 C2 . DE 3 151 407 C1 and EP 0 219 011 B1 Various methods for laser inscription of security and / or value documents are known. With such methods, personalized information can be incorporated into internal layers of a security and / or value document and are thus very well secured against manipulation. However, by means of these methods it is not possible to introduce colored personalized information, such as full-color passport pictures.

From the literature US 6,685,312 . US 6,932,527 . US Pat. No. 6,979,141 . US 7,037,013 . US 6,022,429 and US Pat. No. 6,264,296 various methods for the production of security and / or documents of value are known, applied to a finished blank an ink jet printing layer and then optionally with a protective lacquer or a protective film, the ink jet printing layer to protect against mechanical and / or chemical damage or manipulation is protected. These methods are therefore essentially suitable for decentralized personalization. Although colored personalized information can be applied to the security and / or valuable document with these methods, the resulting very close-to-surface arrangement, due to the nature of the assembly, does not provide sufficient security against manipulation of the personalized information because the protective film does not have a monolithic connection with the substrate received.

Also the document WO 2005/098746 A discloses a method for producing a security and / or value document ("ID document") comprising a polymer layer composite, wherein the polymer layer composite is formed from a polymer layer subassembly and a polymer cover layer and wherein the polymer layer subassembly and / or the polymer cover layer contains a laser-sensitive component.

Technical problem of the invention

The invention is based on the technical problem of specifying a method for producing a security and / or value document in which colored personalized information is secured with high security against manipulation, and which can be carried out both centrally, semidetentrally and decentrally. Principles of the Invention and Preferred Embodiments To solve this technical problem, the invention teaches a method for producing a security and / or value document comprising a polymer layer composite or consisting thereof, wherein the polymer layer composite is formed from a polymer layer part composite and a polymer cover layer and wherein the polymer layer part composite and / or the polymer topcoat a laser-sensitive component or a plurality of laser-sensitive components, comprising the following method steps: A) first personalized information is applied to the polymer layer subassembly by means of an inkjet printing process as a colored inkjet printing layer, B) at least one polymer cover layer is applied to the inkjet printing layer and combined with the polymer layer subassembly by thermal lamination, and C) by means of laser engraving, a second personalized information is introduced into the polymer layer composite of the security and / or value document obtained in step B). The step C), introduction of the laser engraving, can alternatively be carried out before the steps A) and / or B). The advantage of this embodiment is that no interaction between the laser radiation and the inkjet printing layer can occur. Furthermore, an inserted (black) personalization can be overprinted over the entire surface and thus hidden from view. If the overprinting ink is IR-transparent, then this hidden information can be read by machine.

With the invention it is achieved that the first personalized information in color is integrated into the security and / or value document and integrated in a monolithic composite which is formed by the thermal lamination of the polymer layer part composite with the polymer cover layer. As a result, a very high security against manipulation is ensured since a manipulation by detachment of the polymer topcoat practically impossible. For in the thermal lamination, the polymer layer component composite and the polymer cover layer are essentially bonded to one another in a materially bonded manner.

A polymer layer subassembly is also referred to as a card or document blank. As a rule, it is formed from a plurality of polymer layers, wherein at least one of the polymer layers, usually a plurality of polymer layers, can or can carry a print layer. One of the polymer layers may also carry an electronic circuit (integrated circuit, IC), a display module or other electronic circuit, or contain this component embedded. The polymer layers of the polymer layer subassembly are joined together, for example by gluing, or else by thermal lamination. However, the term "polymer layer component composite" also encompasses monolithically produced card blanks, for example by way of injection molding or transfer molding, reactive or non-reactive. In this respect, a polymer layer subassembly does not necessarily have to be made of several polymer layers. But this will be the case with most security and / or value documents.

This thermal lamination can take place at temperatures between 140 to 270 ° C., preferably 140 to 210 ° C., and pressures (specific pressure directly at the workpiece) of 1 to 10 bar, in particular 3 to 7 bar.

After stage B) (and before and / or after stage C)), a visual inspection may take place to detect defects of thermal lamination joining.

In principle, all materials which are customary in the field of security and / or value documents can be used as materials for the polymer layer part composite and the polymer top layer. The polymer materials can, identically or differently, be based on a polymer material selected from the group consisting of "PC (polycarbonate, especially bisphenol A polycarbonate), PET (polyethylene glycol terephthalate), PMMA (polymethyl methacrylate), TPU (thermoplastic polyurethane elastomers), PE (polyethylene), PP (polypropylene), PI (polyimide or poly-trans-isoprene), PVC (polyvinyl chloride) and copolymers of such polymers. Preference is given to the use of PC materials, wherein, for example, so-called low-Tg materials can be used in particular for the polymer topcoat.

Low-T _g materials are polymers whose glass transition temperature is below 140 ° C. In this case, it is preferred if the polymer layer partial composite and the polymer cover layer are formed from identical or different polymers, wherein at least the base polymer of the polymer cover layer, preferably also the base polymer of the polymer layer partial composite, contains identical or different mutually reactive groups, wherein at a laminating temperature of less than 200 ° C reactive groups of the polymer topcoat with each other and / or react with reactive groups of the polymer layer component composite and a covalent bond with each other. As a result, the lamination temperature can be lowered without jeopardizing the intimate bond of the laminated layers. This is due to the fact that (in the case of reactive groups both in the polymer layer component composite and in the polymer cover layer) the various polymer layers can no longer be readily delaminated due to the reaction of the respective reactive groups. Because there is a reactive coupling between the layers, as it were a reactive lamination. Second, because of the lower lamination temperature, it is possible to prevent a change in the color ink-jet printing layer, especially a color change. It is preferred if the glass transition temperature Tg of the polymer topcoat prior to thermal lamination is less than 120 ° C (or less than 110 ° C or 100 ° C), the glass transition temperature of this polymer layer after thermal lamination by reaction of reactive groups of Base polymer of the polymer layer with each other by at least 5 ° C, preferably at least 20 ° C, higher than the glass transition temperature before the thermal lamination. In this case, there is not (only) a reactive coupling of the layers to be laminated with one another, but an increase in the molecular weight and thus in the glass transition temperature takes place through crosslinking of the polymer within the layer and between the layers. This complicates delamination in addition. Preferably, the lamination temperature in step B) when using such polymer materials less than 180 ° C, more preferably still less than 150 ° C. The selection of suitable reactive groups is easily possible for the person skilled in 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, -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 can be any reactive or non-reactive group, for example -H, -Hal, C ₁ - C ₂₀ 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, such as the reaction partners of the Diels-Alder reaction or a metathesis." The reactive groups can be attached directly to the base polymer or attached to the base polymer via a spacer group ann for polymer chemistry known spacer groups in question. 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 well 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 consisting of "- (CH ₂ ) _n -, - (CH ₂ -CH ₂ -O) _n -, - (SiR ₂ -O) _n -, - (C 6 H ₄ ) _n -, - (C ₆ H ₁₀ ) n, C ₁ -C _n -alkyl, C ₃ -C _{(n + 3)} -aryl, C ₄ -C _{(n + 4)} -ArAlkyl, each branched or linear , saturated or unsaturated, optionally substituted, or corresponding heterocycles with one or more a plurality of 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 Encyclopedia of Industrial Chemistry ", Wiley Verlag, electronic edition 2007 , referenced. The term "base polymer" in the context of the above statements denotes a polymer structure which does not carry any reactive groups under the lamination conditions used. These may be homopolymers or copolymers. There are also modified polymers compared to said polymers.

In the context of the invention, it is also possible for the side of the polymer layer part composite facing the polymer cover layer to be chemically modified before or after printing with the inkjet printing layer in such a way that reactive groups described above are bonded to the surface.

In a development of the invention, the polymer layer subassembly contains an electronic circuit or an electronic circuit (laminated or embedded), wherein a third personalized information is stored in front of, in particular immediately before, at the same time or after the step C) in the electronic circuit. It is expedient if the polymer layer subassembly on the side of the electronic circuit and / or on the side opposite the electronic circuit, at least in the region of the electronic circuit, preferably has opaque printing. Thereby, the electronic circuit can be protected against exposure to light, or it can be a converter layer according to the literature EP 4106463 be introduced.

The laser-sensitive component is set up in the polymer layer subassembly and / or in the polymer cover layer. It is preferred if (only) the polymer layer composite contains a laser-sensitive layer. A manipulation attempt is made more difficult because the personalized information produced by laser engraving remains deeply embedded in the polymer layer composite, even if the polymer topcoat and the ink jet printing layer are removed.

In step A, a personalized colored ink jet printing layer can be applied to one or both sides of the polymer layer subassembly. Then, but not necessarily, the colored ink-jet printing layers on each of the sides may respectively represent partial information of the first personalized information and optionally be arranged complementary to one another and register-accurate. In other words, the various ink-jet printing layers represent partial images of an overall image.

In another embodiment, in step A, personalized colored inkjet print layers are applied to both sides of the polymer layer subassembly. In this case, however, the card body of the polymer layer part composite is not transparent, so that both print layers contain independent personalization information.

In the invention, the first personalized information is the color portion of personalized overall picture information, the second personalized information being the black portion of the personalized overall picture information. In this case, the overall image information is first generated by both the ink jet printing layer and the laser engraving, the ink jet printing layer representing a first partial image and the laser engraving a second partial image of the overall image information. It is understood that in this case the sub-images must be generated or mounted in register with each other. In this case, it is particularly preferred that the black portion is first introduced (stage C), since an accurate alignment of the inkjet pressure (stage A) is technically easier to implement. This is followed by lamination (level B).

Optionally, before or after stage B) or C), an optical test of the colored inkjet printing layer and / or an electronic test of the electronic circuit, in particular of the electronic circuit or display module can be performed.

The polymer layer subassembly may be provided internally or on one or both sides additionally with a printing layer which is applied with a non-inkjet printing technology. These include the classic ones Printing processes such as high-pressure (direct and indirect), planographic printing in the types of offset printing, wet and waterless, through-printing (screen printing), digital and in particular engraving and gravure printing.

The invention further relates to a security and / or value document comprising a polymer layer subassembly and a polymer cover layer, or consisting thereof, wherein between the polymer layer subassembly and the polymer cover layer is arranged by means of ink jet ink jet printed ink layer with a first personalized information, and wherein in the Polymer layer subassembly and / or the polymer cover layer containing a laser-sensitive component, a laser engraved second personalized information is arranged. The comments on the method described above apply analogously.

The first personalized information or the personalized overall image information will typically be an image representation, in particular a passport photograph of a person.

The second personalized information may include or consist of a personalized string. This may be, for example, the name of the person concerned, their date of birth, and / or their address, etc. The second personalized information can also be document-individual Information, such as serial number or issue date, includes or consists of.

The polymer layer part composite may have a thickness in the range from 200 to 2000 .mu.m, in particular from 400 to 1500 .mu.m. The polymer topcoat may have a thickness in the range of 5 to 270 μm, preferably 10 to 120 μm, most preferably 20 to 120 μm.

Die Kettenabbrecher werden im allgemeinen in Mengen von 0,5 bis 10, bevorzugt 1,5 bis 8 Mol-%, bezogen auf eingesetzte Diphenole, eingesetzt. Die Polycarbonatderivate können vorzugsweise nach dem Phasengrenzflächenverhalten (vgl. H. Schnell "Chemistry and Physics of Polycarbonates", Polymer Reviews, Vol. IX, Seite 33ff., Interscience Publ. 1964) in an sich bekannter Weise hergestellt werden. Hierbei werden die Diphenole der Formel (Ia) in wässrig alkalischer Phase gelöst. Zur Herstellung von Copolycarbonaten mit anderen Diphenolen werden Gemische von Diphenolen der Formel (Ia) und den anderen Diphenolen, beispielsweise denen der Formel (Ib), eingesetzt. Zur Regulierung des Molekulargewichts können Kettenabbrecher z.B. der Formel (Ic) zugegeben werden.

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, it can be reduced in a known manner by condensing Amounts, preferably amounts between 0.05 and 2.0 mol% (based on diphenols used), of trifunctional or more than trifunctional compounds, in particular those having three or more than three phenolic hydroxyl groups, can be achieved.

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.

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.

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 process 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.

Example 1: Reference Manufacturing Process

In the FIG. 1 recognizes that in the stage a) a document blank 1, for example, as in the FIG. 3 shown, is used. In the example, the document blank 1 has a polymer layer 2 of thickness 300 μm with a chip 3 and an antenna 4. On both sides of the polymer layer 2 are opaque polymer layers 5, 6 of thickness 100 microns set up, which can optionally be printed on each side and independently on one side or on both sides. On both sides of the polymer layers 5, 6 transparent polymer layers 7, 8 are arranged, which have a thickness of 100 microns. The polymer layer 8 may be printed on one side or on both sides. The polymer layer 8 is followed by a 50 μm thick and transparent polymer layer 9.

Again the presentation of the FIG. 1 It can be seen that the document blank in step b) is provided on one side by means of an inkjet printing layer 10, the inkjet printing layer 10 being personalized information, for example as a passport photograph. All colors (for example, with the basic colors cyan, magenta and yellow) are printable and black. Optionally, in step c) drying and / or optical testing of the closes Ink jet printing layer 10 on. In particular, the optical check serves to identify defects in the ink jet printing layer, for example by clogged nozzles, to invalidate the security and / or value document and to re-initiate personalization with the relevant information. It is expedient for detection of errors when a cleaning cycle or replacement of the print head for the purpose of cleaning or renewal is carried out before the further printing of document blanks 1. In the step d), a polymer coating layer 11 is placed on the side of the document blank 1 with the ink jet printing layer and thermally laminated with the document blank 1. The polymer material of the polymer cover layer 11 is compatible with the polymer material in the region of the surface of the document blank 1, possibly even equal to it, so that a monolithic block of document blank 1 and polymer cover layer 11 is formed during lamination. In step e) then carried the introduction of other personalized information, such as name, address, place of birth, date of birth, document number, etc., by means of laser engraving. This can also include tilting effects. In the optional step f), a visual check of the laser engraving can take place. In the optional step g) then the storage of personalized data in the chip 3. In the optional stage h) an electronic check of the personalized data in the chip 3 and possibly checking the stored data to be concordant with the personalized information of the inkjet printing layer 10 and / or the laser engraving. Finally, a security and / or value document is obtained, as in US Pat FIG. 4 shown. A composite of document blank 1, inkjet printing layer 10 and polymer cover layer 11 (exploded in the illustration) can be seen.

If the document blank 1 is a data page for a multi-page security and / or value document, such as a passport, the security and / or value document is paged before step a), so that the page, on which the ink jet printing layer is to be attached, is exposed. Then the steps are executed as shown. Subsequently, it is optionally possible to scroll further and to personalize further sheets of the security and / or value document. Furthermore, a serial number can optionally be introduced in all pass pages, for example by means of laser perforation.

Example 2 Inventive Production Process

In the FIG. 2 an inventive manufacturing process is shown. This differs essentially in that in step b) an inkjet printing layer is printed without black. For this purpose, in the context of stage e) the laser engraving is (also) characterized in that the missing black pixels are added to the image generated in stage b). It arises as a result Image whose colored components on the one hand and its black components on the other hand are arranged in different layers, whereby an increased security against manipulation is obtained. The other structure corresponds to the representations of FIGS. 3 and 4 ,

Example 3 Inventive Production Process

In the FIG. 5 a further production process according to the invention is shown. This differs essentially in that in step e) the laser personalization is carried out before the steps b) of the ink-jet personalization. Here, the laser personalization again black components of the colored ink-jet image, as well as suitable position marks included. This variant has the advantage that due to the adaptable inkjet technology, a positionally accurate alignment of the inkjet layer with the laser engraving can be achieved, in particular by using a local registration on the inkjet head. The other structure corresponds to the representations of FIGS. 3 and 4 ,
