definitions

When Paint or ink will be printable as described here Composition or any printable material. This means that any composition or any material that prints be applied to a substrate layer surface, represent a (printed) color or ink. A resulting color layer or ink layer represents a print layer. This does not have to necessarily a perceptible to the human observer Have color. A transparent print layer is thus in this Meaning also a color layer. A structured print layer presents again a printing structure.

A Light guiding structure is a structure that is capable of electromagnetic Radiation, preferably light in the visible wavelength range, due to total internal reflection at an interface of the light guide structure conduct.

Luminescent substances are materials or substances which, upon excitation of an atomic or molecular excited state, emit electromagnetic radiation, preferably in the visible wavelength range, into a low-energy state. Also more complex electronic Transitions with the emission of photons are considered as luminescence processes. Depending on the physical and / or chemical processes different luminescence processes are distinguished. In the context of the described here, it does not matter which luminescence process the luminescent substance uses. These may be, for example, electroluminescence, cathodoluminescence, photoluminescence, in particular fluorescence or phosphorescence or also more-photon processes (eg so-called upconversion processes), chemoluminescence, bioluminescence, triboluminescence, thermoluminescence, sonoluminescence, radioluminescence and also piezoluminescence.

Since these are separated from each other the side surfaces or the side surfaces of the document body are formed, enters the light coupled into the light guide at different locations from the Lichtleitstruktur and the document body out. This results in a light emission pattern, which is characteristic for the structure of the light guiding structure. Thus it is possible, via the structuring of the light guide structure To encode information into the value and / or security document. Preferably, such a coding is individualizing, preferably personalized.

A individualizing information is one piece of information, the other two makes identical objects distinguishable.

One Decoupling of the light, however, preferably takes place from the coupling regions, because the light is directed to these areas via light pipes becomes. To leakage of light from the top and / or bottom of the document body is in some embodiments provided that between the top and the light guide structure and / or the bottom of the document body and the Lichtleitstruktur in each case an opaque element is arranged.

In principle, all polymer layers which are customarily used in the field of security and / or value documents can be used as materials for the substrate layers. The polymer layers can, identically or differently, be based on a polymer material from the group comprising 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, whereby, for example, but by no means necessarily, also so-called low-T _g materials can be used, in particular for a polymer layer on which a printing layer is applied, and / or for a polymer layer which is coated with a polymer layer, which carries a printing layer, is connected on the side with the printing layer. Low-T _g materials are polymers whose glass transition temperature is below 140 ° C.

It is preferred if the base polymer of at least one of the polymer layers to be joined contains identical or different mutually reactive groups, wherein react at a laminating temperature of less than 200 ° C reactive groups of a first polymer layer with each other and / or with reactive groups of a second polymer layer. As a result, the lamination temperature can be lowered without jeopardizing the intimate bond of the laminated layers. In the case of various polymer layers having reactive groups, this is due to the fact that the various polymer layers can no longer be readily delaminated due to the reaction of the respective reactive groups. Because there is a reactive coupling between the polymer layers, as it were a reactive lamination. Furthermore, due to the lower lamination temperature, it is possible to prevent a change in a colored printing layer, in particular a color change, from being prevented. It is advantageous if the glass transition temperature T _{g of} the at least one polymer layer before thermal lamination is less than 120 ° C (or less than 110 ° C or less than 100 ° C), the glass transition temperature of this polymer layer after the thermal lamination Reaction of reactive groups of the base polymer of the polymer layer with each other by at least 5 ° C, preferably at least 20 ° C, higher than the glass transition temperature before the thermal lamination. In this case, not only is a reactive coupling of the layers to be laminated together carried out, but rather an increase in the molecular weight and thus in the glass transition temperature takes place by crosslinking of the polymer within the layer and between the layers. This complicates delamination in addition, especially as in a manipulation attempt, the high delamination temperatures necessary, for example, the colors irreversibly damaged and the document is thereby destroyed.

Preferably, the lamination temperature when using such polymer materials less than 180 ° C, more preferably still less than 150 ° C. The choice of suitable reactive groups is readily possible for a person skilled in the art of polymer chemistry. Exemplary reactive groups are selected from the group consisting of -CN, -OCN, -NCO, -NC, -SH, -S _x, -Tos, -SCN, -NCS, -H, epoxy (-CHOCH _2), -NH ₂ , -NN ⁺ , -NN-R, -OH, -COOH, -CHO, -COOR, -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 non-reactive group, for example -H, -Hal, C C ₁ -C ₂₀ -alkyl, C ₃ -C ₂₀ -aryl, C ₄ -C ₂₀ -aralkyl, in each case branched or linear, saturated or unsaturated, optionally substituted, or corresponding heterocycles having one or more identical or different heteroatoms N, O, or S. Other reactive groups are of course possible. These include the reaction partners of the Diels-Alder reaction or a metathesis. The reactive groups may be attached directly to the base polymer or linked to the base polymer via a spacer group. Suitable spacer groups are all spacer groups known to the person skilled in the art of polymer chemistry. The spacer groups may also be oligomers or polymers which impart elasticity, whereby a risk of breakage of the security and / or value document is reduced. Such elasticity-promoting spacer groups are known to the person skilled in the art and therefore need not be further described here. By way of example only, spacer groups may be mentioned which are selected from the group comprising - (CH ₂ ) _n -, - (CH ₂ -CH ₂ -O) _n -, - (SiR ₂ -O) _n -, - (C ₆ 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, respectively branched or linear, saturated or unsaturated, optionally substituted, or corresponding heterocycles having one or more identical or different heteroatoms O, N, or S, where n = 1 to 20, preferably 1 to 10. Regarding further reactive groups or possibilities of modification will be on the reference "Ullmann's Encyclopedia of Industrial Chemistry", Wiley Verlag, electronic edition 2006 , referenced. The term "base polymer" in the context of the above statements designates a polymer structure which does not bear any groups reactive under the lamination conditions used. These may be homopolymers or copolymers. There are also modified polymers compared to said polymers.

Die Zubereitung kann im Detail enthalten: A) 0,1 bis 10 Gew.-%, insbesondere 0,5 bis 5 Gew.-%, eines Bindemittels mit einem Polycarbonatderivat auf Basis eines geminal disubstituierten Dihydroxydiphenylcycloalkans, B) 40 bis 99,9 Gew.-%, insbesondere 45 bis 99,5 Gew.-%, eines organischen Lösungsmittels oder Lösungsmittelgemischs, C) 0,1 bis 6 Gew.-%, insbesondere 0,5 bis 4 Gew.-%, eines Farbmittels oder Farbmittelgemischs, D) 0,001 bis 6 Gew.-%, insbesondere 0,1 bis 4 Gew.-%, eines funktionales Materials oder einer Mischung funktionaler Materialien, E) 0,1 bis 30 Gew.-%, insbesondere 1 bis 20 Gew.-%, Additive und/oder Hilfsstoffe, oder eine Mischung solcher Stoffe. Als Komponente C, sofern ein Farbmittel vorgesehen sein soll, kommt grundsätzlich jedes beliebige Farbmittel oder Farbmittelgemisch in Frage. Unter Farbmittel sind alle farbgebenden Stoffe bezeichnet. Das bedeutet, es kann sich sowohl um Farbstoffe (einen Überblick über Farbstoffe gibt Ullmann's Encyclopedia of Industrial Chemistry, Electronic Release 2007, Wiley Verlag, Kapitel „Dyes, General Survey” ) wie auch um Pigmente (einen Überblick über organische wie anorganische Pigmente gibt Ullmann's Encyclopedia of Industrial Chemistry, Electronic Release 2007, Wiley Verlag, Kapitel „Pigments, Organic” bzw. ”Pigments, Inorganic” ) handeln. Farbstoffe sollten in den Lösungsmitteln der Komponente B löslich bzw. (stabil) dispergierbar oder suspendierbar sein. Des Weiteren ist es vorteilhaft, wenn das Farbmittel bei Temperaturen von 160°C und mehr für einen Zeitraum von mehr als 5 min. stabil, insbesondere farbstabil ist. Es ist auch möglich, dass das Farbmittel einer vorgegebenen und reproduzierbaren Farbveränderung unter den Verarbeitungsbedingungen unterworfen ist und entsprechend ausgewählt wird. Pigmente müssen neben der Temperaturstabilität insbesondere in feinster Partikelgrößenverteilung vorliegen. Für einen Tintenstrahldruck bedeutet dies in der Praxis, dass die Teilchengröße nicht über 1,0 μm hinausgehen sollte, da sonst Verstopfungen im Druckkopf die Folge sind. In der Regel haben sich nanoskalige Festkörperpigmente und gelöste Farbstoffe bewährt. Die Farbmittel können kationisch, anionisch oder auch neutral sein. Lediglich als Beispiele für im Tintenstrahldruck verwendbare Farbmittel seinen genannt:

Weitere geeignete Farbmittel sind in der Literaturstelle Ullmann's Encyclopedia of Industrial Chemistry, Electronic Release 2008, Wiley Verlag, Kapitel ”Colorants Used in Ink Jet Inks” beschrieben. Gut lösliche Farbmittel führen zu einer optimalen Integration in die Matrix bzw. das Bindemittel der Druckschicht. Die Farbmittel können entweder direkt als Farbstoff bzw. Pigment zugesetzt werden oder als Paste, einem Gemisch aus Farbstoff und Pigment zusammen mit einem weiteren Bindemittel. Dieses zusätzliche Bindemittel sollte chemisch kompatibel mit den weiteren Komponenten der Zubereitung sein. Sofern eine solche Paste als Farbmittel eingesetzt wird, bezieht sich die Mengenangabe der Komponente B auf das Farbmittel ohne die sonstigen Komponenten der Paste. Diese sonstigen Komponenten der Paste sind dann unter die Komponente E zu subsumieren. Bei Verwendung von so genannten Buntpigmenten in den Skalenfarben Cyan-Magenta-Yellow und bevorzugt auch (Ruß)-Schwarz sind Volltonfarbabbildungen möglich. Die Komponente D umfasst Substanzen, die unter Einsatz von technischen Hilfsmitteln unmittelbar durch das menschliche Auge oder durch Verwendung von geeigneten Detektoren ersichtlich sind. Hier sind die dem Fachmann einschlägig bekannten Materialien (vgl. auch van Renesse in: Optical document security, 3rd Ed., Artech House, 2005) gemeint, die zur Absicherung von Wert und Sicherheitsdokumenten eingesetzt werden. Dazu zählen Lumineszenzstoffe (Farbstoffe oder Pigmente, organisch oder anorganisch) wie z. B. Photoluminophore, Elektroluminophore, Antistokes Luminophore, Fluorophore aber auch magnetisierbare, photoakustisch adressierbare oder piezoelektrische Materialien. Des Weiteren können Raman-aktive oder Ramanverstärkende Materialien eingesetzt werden, ebenso wie so genannte Barcode-Materialien. Auch hier gelten als bevorzugte Kriterien entweder die Löslichkeit in der Komponente B oder bei pigmentierten Systemen Teilchengrößen < 1 μm sowie eine Temperaturstabilität für Temperaturen > 160°C im Sinne der Ausführungen zur Komponente C. Funktionale Materialien können direkt zugegeben werden oder über eine Paste, d. h. einem Gemisch mit einem weiteren Bindemittel, welches dann Bestandteil der Komponente E bildet, oder dem eingesetzten Bindemittel der Komponente A. Die Komponente E umfasst bei Tinten für einen Tintenstrahldruck üblicherweise eingerichtete Stoffe wie Antischaummittel, Stellmittel, Netzmittel, Tenside, Fließmittel, Trockner, Katalysatoren, (Licht-)Stabilisatoren, Konservierungsmittel, Biozide, Tenside, organische Polymere zur Viskositätseinstellung, Puffersysteme, etc. Als Stellmittel kommen fachübliche Stellsalze in Frage. Ein Beispiel hierfür ist Natriumlactat. Als Biozide kommen alle handelsüblichen Konservierungsmittel, welche für Tinten verwendet werden, in Frage. Beispiele hierfür sind Proxel^®GXL und Parmetol^® A26. Als Tenside kommen alle handelsüblichen Tenside, welche für Tinten verwendet werden, in Frage. Bevorzugt sind amphotere oder nichtionische Tenside. Selbstverständlich ist aber auch der Einsatz spezieller anionischer oder kationischer Tenside, welche die Eigenschaften des Farbstoffs nicht verändern, möglich. Beispiele für geeignete Tenside sind Betaine, ethoxilierte Diole usw. Beispiele sind die Produktreihen Surfynol^® und Tergitol^®. Die Menge an Tensiden wird insbesondere bei Anwendung für den Tintenstrahldruck beispielsweise mit der Maßgabe gewählt, dass die Oberflächenspannung der Tinte im Bereich von 10 bis 60 mN/m, vorzugsweise 20 bis 45 mN/m, gemessen bei 25°C, liegt. Es kann ein Puffersystem eingerichtet sein, welches den pH-Wert im Bereich von 2,5 bis 8,5, insbesondere im Bereich von 5 bis 8, stabilisiert. Geeignete Puffersysteme sind Lithiumacetat, Boratpuffer, Triethanolamin oder Essigsäure/Natriumacetat. Ein Puffersystem wird insbesondere im Falle einer im Wesentlichen wässrigen Komponente B in Frage kommen. Zur Einstellung der Viskosität der Tinte können (ggf. wasserlösliche) Polymere vorgesehen sein. Hier kommen alle für übliche Tintenformulierungen geeigneten Polymere in Frage. Beispiele sind wasserlösliche Stärke, insbesondere mit einem mittleren Molekulargewicht von 3.000 bis 7.000, Polyvinylpyrrolidon, insbesondere mit einem mittleren Molekulargewicht von 25.000 bis 250.000, Polyvinylalkohol, insbesondere mit einem mittleren Molekulargewicht von 10.000 bis 20.000, Xanthan-Gummi, Carboxy-Methylcellulose, Ethylenoxid/Propylenoxid-Blockcopolymer, insbesondere mit einem mittleren Molekulargewicht von 1.000 bis 8.000. Ein Beispiel für das letztgenannte Blockcopolymer ist die Produktreihe Pluronic^®. Der Anteil an Biozid, bezogen auf die Gesamtmenge an Tinte, kann im Bereich von 0 bis 0,5 Gew-%, vorzugsweise 0,1 bis 0,3 Gew.-%, liegen. Der Anteil an Tensid, bezogen auf die Gesamtmenge an Tinte, kann im Bereich von 0 bis 0,2 Gew.-% liegen. Der Anteil an Stellmitteln kann, bezogen auf die Gesamtmenge an Tinte, 0 bis 1 Gew.-%, vorzugsweise 0,1 bis 0,5 Gew.-%, betragen. Zu den Hilfsmitteln werden auch sonstige Komponenten gezählt, wie beispielsweise Essigsäure, Ameisensäure oder n-Methyl-Pyrolidon oder sonstige Polymere aus der eingesetzten Farbstofflösung oder -Paste. Bezüglich Substanzen, welche als Komponente E geeignet sind, wird ergänzend beispielsweise auf Ullmann's Encyclopedia of Chemical Industry, Electronic Release 2008, Wiley Verlag, Kapitel „Paints and Coatings”, Sektion „Paint Additives” , verwiesen. Ferner werden die Materialien, die einen Brechungsindex der Tinte erhöhen zu den Additiven und Hilfsmitteln der Komponente E zugeordnet. Für ein Ausbilden der Lichtleitstruktur werden Tinten bevorzugt, die keine Pigmente größer als 250 nm als Farbmittel enthalten, da diese als Streuzentren eine Lichtleitung negativ beeinflussen.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, may be substituted, and aliphatic radicals or cycloaliphatic radicals other than those of the formula (II) Ia) or heteroatoms may contain as bridge members.

Particularly preferred diphenols of the formula (Ib) are, for example, 2,2-bis (4-hydroxyphenyl) propane, 2,2-bis (3,5-dimethyl-4-hydroxyphenyl) -propane, 2,2-bis- (3,5-dichloro-4-hydroxyphenyl) -propane, 2,2-bis (3,5-dibromo-4-hydroxyphenyl) -propane and 1,1-bis (4-hydroxyphenyl) -cyclohexane. In particular, 2,2-bis (4-hydroxyphenyl) propane is preferred. The other diphenols can be used both individually and in a mixture. The molar ratio of diphenols of the formula (Ia) to the other diphenols of the formula (Ib) which may optionally be used should be between 100 mol% (Ia) to 0 mol% (Ib) and 2 mol% (Ia) 98 mol% (Ib), preferably between 100 mol% (Ia) to 0 mol% (Ib) and 10 mol% (Ia) to 90 mol% (Ib) and in particular 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 NEN be branched in a conventional manner. If the branching is desired, this can in known manner by condensing small amounts, preferably amounts of 0.05 to 2.0 mol% (based on diphenols), of trifunctional or more than trifunctional compounds, in particular those with three or more than three phenolic hydroxyl groups can be achieved. Some branching agents having three or more than three phenolic hydroxyl groups are phloroglucinol, 4,6-dimethyl-2,4,6-tri- (4-hydroxyphenyl) -heptene-2,4,6-dimethyl-2,4,6-tri - (4-hydroxyphenyl) heptane, 1,3,5-tri (4-hydroxyphenyl) benzene, 1,1,1-tri- (4-hydroxyphenyl) -ethane, tri- (4-hydroxyphenyl) -phenylmethane , 2,2-bis [4,4-bis (4-hydroxyphenyl) cyclohexyl] propane, 2,4-bis (4-hydroxyphenyl-isopropyl) -phenol, 2,6-bis (2-bis) hydroxy-5-methylbenzyl) -4-methylphenol, 2- (4-hydroxyphenyl) -2- (2,4-dihydroxyphenyl) -propane, hexa- [4- (4-hydroxyphenyl-isopropyl) -phenyl] -orthoterephthalic acid ester , Tetra (4-hydroxyphenyl) methane, tetra- [4- (4-hydroxyphenyl-isopropyl) -phenoxy] -methane and 1,4-bis- [4 ', 4 "-dihydroxytriphenyl) -methyl] -benzene. Some of the other trifunctional compounds are 2,4-dihydroxybenzoic acid, trimesic acid, cyanuric chloride and 3,3-bis (3-methyl-4-hydroxyphenyl) -2-oxo-2,3-dihydroindole. As chain terminators known per se regulation of the molecular weight of the polycarbonate derivatives are monofunctional compounds in conventional concentrates. Suitable compounds are for. As phenol, tert-butylphenols or other alkyl-substituted phenols. For controlling the molecular weight, in particular small amounts of phenols of the formula (Ic) are suitable

wherein R represents a branched C ₈ and / or C ₉ alkyl radical. Preferably, in the alkyl radical R, the proportion of CH ₃ protons between 47 and 89% and the proportion of CH and CH ₂ protons between 53 and 11%; also preferably R is in the o- and / or p-position to the OH group, and more preferably the upper limit of the ortho-portion is 20%. The chain terminators are generally used in amounts of 0.5 to 10, preferably 1.5 to 8 mol%, based on diphenols used. The polycarbonate derivatives may preferably be prepared according to the interfacial behavior (cf. H. Schnell in. Chemistry and Physics of Polycarbonates, Polymer Reviews, Vol. IX, page 33 et seq., Interscience Publ. 1964 ) are prepared in a conventional manner. In this case, the diphenols of the formula (Ia) are dissolved in an aqueous alkaline phase. For the preparation of copolycarbonates with other diphenols, mixtures of diphenols of the formula (Ia) and the other diphenols, for example those of the formula (Ib), are used. To regulate the molecular weight chain terminators z. B. the formula (Ic) are added. Then, in the presence of an inert, preferably polycarbonate-dissolving, organic phase is reacted with phosgene by the method of interfacial condensation. The reaction temperature is in the range of 0 ° C to 40 ° C. The optionally used with branching agents (preferably 0.05 to 2.0 mol%) can be presented either with the diphenols in the aqueous alkaline phase or dissolved in the organic solvent added before phosgenation. In addition to the diphenols of the formula (Ia) and, if appropriate, other diphenols (Ib), their mono- and / or bis-chlorocarbonic acid esters may also be used, these being added dissolved in organic solvents. The amount of chain terminators and of branching agents then depends on the molar amount of diphenolate radicals corresponding to formula (Ia) and optionally formula (Ib); When using chloroformates the amount of phosgene can be reduced accordingly in a known manner. Suitable organic solvents for the chain terminators and optionally for the branching agents and the chloroformates are, for example, methylene chloride, chlorobenzene and in particular mixtures of methylene chloride and chlorobenzene. Optionally, the chain terminators and branching agents used can be dissolved in the same solvent. For example, methylene chloride, chlorobenzene and mixtures of methylene chloride and chlorobenzene serve as the organic phase for the interfacial polycondensation. The aqueous alkaline phase used is, for example, NaOH solution. The preparation of the polycarbonate derivatives by the interfacial process can be catalyzed in a conventional manner by catalysts such as tertiary amines, in particular tertiary aliphatic amines such as tributylamine or triethylamine; the catalysts can be used in amounts of 0.05 to 10 mol%, based on moles of diphenols used. The catalysts can be added before the beginning of the phosgenation or during or after the phosgenation. The polycarbonate derivatives can be prepared by the known method in the homogeneous phase, the so-called "pyridine process" and by the known melt transesterification process using, for example, diphenyl carbonate instead of phosgene. The polycarbonate derivatives may be linear or branched, they are homopolycarbonates or copolycarbonates based on the diphenols of the formula (Ia). By arbitrary composition with other diphenols, in particular with those of the formula (Ib), the polycarbonate properties can be varied in a favorable manner. In such copolycarbonates are the diphenols of the formula (Ia) in amounts of 100 mol% to 2 mol%, preferably in amounts of 100 mol% to 10 mol% and in particular in amounts of 100 mol% to 30 mol%, based on the total amount of 100 mol% of diphenol units contained in polycarbonate derivatives. The polycarbonate derivative may be a copolymer comprising, in particular consisting thereof, monomer units M1 based on the formula (Ib), preferably, bisphenol A, and monomer units M2 based on the geminally disubstituted dihydroxydiphenylcycloalkane, preferably the 4,4 '' - (3,3, 5-trimethylcyclohexane-1,1-diyl) diphenol, wherein the molar ratio M2 / M1 is preferably greater than 0.3, in particular greater than 0.4, for example greater than 0.5. It is preferred that the polycarbonate derivative has a weight average molecular weight of at least 10,000, preferably from 20,000 to 300,000. In principle, component B may be substantially organic or aqueous. Substantially aqueous means that up to 20% by weight of component B) can be organic solvents. Substantially organic means that up to 5% by weight of water may be present in component B). Component B preferably contains one or consists of a liquid aliphatic, cycloaliphatic and / or aromatic hydrocarbon, a liquid organic ester and / or a mixture of such substances. The organic solvents used are preferably halogen-free organic solvents. Particularly suitable are aliphatic, cycloaliphatic, aromatic hydrocarbons, such as mesitylene, 1,2,4-trimethylbenzene, cumene and solvent naphtha, toluene, xylene; (organic) esters such as methyl acetate, ethyl acetate, butyl acetate, methoxypropyl acetate, ethyl 3-ethoxypropionate. Preference is given to mesitylene, 1,2,4-trimethylbenzene, cumene and solvent naphtha, toluene, xylene, methyl acetate, ethyl acetate, methoxypropyl acetate. Ethyl 3-ethoxypropionate. Very particular preference is given to mesitylene (1,3,5-trimethylbenzene), 1,2,4-trimethylbenzene, cumene (2-phenylpropane), solvent naphtha and ethyl 3-ethoxypropionate. A suitable solvent mixture comprises, for example, L1) 0 to 10% by weight, preferably 1 to 5% by weight, in particular 2 to 3% by weight, mesitylene, L2) 10 to 50% by weight, preferably 25 to 50% by weight %, in particular 30 to 40% by weight, 1-methoxy-2-propanol acetate, L3) 0 to 20% by weight, preferably 1 to 20% by weight, in particular 7 to 15% by weight, 1 , 2,4-trimethylbenzene, L4) 10 to 50 wt.%, Preferably 25 to 50 wt.%, In particular 30 to 40 wt.%, Ethyl 3-ethoxypropionate, L5) 0 to 10 wt. , preferably 0.01 to 2 wt .-%, in particular 0.05 to 0.5 wt .-%, cumene, and L6) 0 to 80 wt .-%, preferably 1 to 40 wt .-%, in particular 15 to 25 wt .-%, solvent naphtha, wherein the sum of components L1 to L6 always gives 100 wt .-%. The preparation may contain in detail: A) 0.1 to 10 wt .-%, in particular 0.5 to 5 wt .-%, of a binder with a polycarbonate derivative based on a geminal disubstituted dihydroxydiphenylcycloalkane, B) 40 to 99.9 wt %, in particular 45 to 99.5% by weight, of an organic solvent or solvent mixture, C) 0.1 to 6% by weight, in particular 0.5 to 4% by weight, of a colorant or colorant mixture, D ) 0.001 to 6 wt .-%, in particular 0.1 to 4 wt .-%, of a functional material or a mixture of functional materials, E) 0.1 to 30 wt .-%, in particular 1 to 20 wt .-%, Additives and / or auxiliaries, or a mixture of such substances. As component C, if a colorant is to be provided, basically any colorant or colorant mixture comes into question. Colorants are all colorants. That means it can be both colorant (a review of dyes there Ullmann's Encyclopedia of Industrial Chemistry, Electronic Release 2007, Wiley Publishing, Chapter "Dyes, General Survey" ) as well as pigments (gives an overview of organic and inorganic pigments Ullmann's Encyclopedia of Industrial Chemistry, Electronic Release 2007, Wiley Verlag, chapter "Pigments, Organic" and "Pigments, Inorganic" ) act. Dyes should be soluble or (stably) dispersible or suspendible in the component B solvents. Furthermore, it is advantageous if the colorant at temperatures of 160 ° C and more for a period of more than 5 min. stable, in particular color-stable. It is also possible that the colorant is subjected to a predetermined and reproducible color change under the processing conditions and is selected accordingly. In addition to the temperature stability, pigments must be present in particular in the finest particle size distribution. For inkjet printing, this means in practice that the particle size should not exceed 1.0 μm, since otherwise blockages in the print head are the result. As a rule, nanoscale solid-state pigments and dissolved dyes have proven their worth. The colorants may be cationic, anionic or even neutral. Just as examples of colorants usable in ink-jet printing its called:
Brilliant black CI no. 28440, chromogen CI no. 14645, direct Tiefschwarz E CI no. 30235, Real Black Salt B CI no. 37245, Real Black Salt K CI no. 37190, Sudan Black HB CI 26150, Naphtolschwarz CI no. 20470, Bayscript ^® Black liquid, CI Basic Black 11, CI Basic Blue 154, Cartasol ^® Turquoise K-ZL liquid, Cartasol ^® Turquoise K-RL liquid (CI Basic Blue 140), Cartasol Blue K5R liquid. Suitable are further z. As the commercially available dyes Hostafine ^® Black TS liquid (sold by Clariant GmbH Germany),
Bayscript ^® Black liquid (CI mixture, sold by Bayer AG Germany), Cartasol ^® Black MG liquid (CI Basic Black 11, Registered trademark of Clariant GmbH Germany), Flexonylschwarz ^® PR 100 (E CI no. 30235, sold by Hoechst AG ), rhodamine B, Cartasol Orange ^® GL K3, K4 Cartasol ^® Yellow GL, Cartasol ^® K GL, or Cartasol ^® Red K-3B. Furthermore, as soluble colorants anthraquinone, Azo, quinophthalone, coumarin, methine, perinone, and / or pyrazole dyes, e.g. B. under the brand name Macrolex ^® available, find use. Other suitable colorants are described in the reference Ullmann's Encyclopedia of Industrial Chemistry, Electronic Release 2008, Wiley Verlag, chapter "Colorants Used in Ink Jet Inks". Well-soluble colorants lead to an optimal integration into the matrix or the binder of the print layer. The colorants may be added either directly as a dye or pigment or as a paste, a mixture of dye and pigment together with another binder. This additional binder should be chemically compatible with the other components of the formulation. If such a paste is used as a colorant, the amount of component B refers to the colorant without the other components of the paste. These other components of the paste are then subsumed under the component E. When using so-called colored pigments in the scale colors cyan-magenta-yellow and preferably also (soot) black solid color images are possible. Component D comprises substances that can be seen directly by the human eye or by the use of suitable detectors using technical aids. Here are the materials known to those skilled in the art (see also van Renesse in: Optical document security, 3rd ed., Artech House, 2005), which are used to secure value and security documents. These include luminescent substances (dyes or pigments, organic or inorganic) such. As photoluminophores, electroluminophores, Antistokes luminophores, fluorophores but also magnetizable, photoacoustically addressable or piezoelectric materials. Furthermore, Raman-active or Raman-enhancing materials can be used, as well as so-called barcode materials. Again, the preferred criteria are either the solubility in the component B or pigmented systems particle sizes <1 micron and a temperature stability for temperatures> 160 ° C in the sense of the comments on the component C. Functional materials can be added directly or via a paste, ie a mixture with a further binder, which then forms part of component E, or the binder of component A. The component E comprises inks for inkjet printing usually furnished substances such as anti-foaming agents, adjusting agents, wetting agents, surfactants, flow agents, dryers, catalysts, (Light) stabilizers, preservatives, biocides, surfactants, organic polymers for viscosity adjustment, buffer systems, etc. Suitable adjusting agents are commercially available actuating salts in question. An example of this is sodium lactate. As biocides, all commercially available preservatives which are used for inks come into question. Examples include Proxel ^® GXL and Parmetol® ^® A26. Suitable surfactants are all commercially available surfactants which are used for inks. Preferred are amphoteric or nonionic surfactants. Of course, it is also possible to use special anionic or cationic surfactants which do not alter the properties of the dye. Examples of suitable surfactants are betaines, ethoxylated diols, etc. Examples are the product lines Surfynol ^® and Tergitol ^®. The amount of surfactants is particularly selected when used for ink-jet printing, for example, provided that the surface tension of the ink is in the range of 10 to 60 mN / m, preferably 20 to 45 mN / m, measured at 25 ° C. A buffer system can be set up which stabilizes the pH in the range from 2.5 to 8.5, in particular in the range from 5 to 8. Suitable buffer systems are lithium acetate, borate buffer, triethanolamine or acetic acid / sodium acetate. A buffer system will be considered in particular in the case of a substantially aqueous component B. To adjust the viscosity of the ink (possibly water-soluble) polymers can be provided. Here all suitable for conventional ink formulations polymers come into question. Examples are water-soluble starch, in particular having an average molecular weight of 3,000 to 7,000, polyvinylpyrrolidone, in particular having an average molecular weight of 25,000 to 250,000, polyvinyl alcohol, in particular having an average molecular weight of 10,000 to 20,000, xanthan gum, carboxymethylcellulose, ethylene oxide / propylene oxide Block copolymer, especially having an average molecular weight of 1,000 to 8,000. An example of the latter block copolymer is the product series Pluronic ^®. The proportion of biocide, based on the total amount of ink, may be in the range of 0 to 0.5% by weight, preferably 0.1 to 0.3% by weight. The proportion of surfactant, based on the total amount of ink, can range from 0 to 0.2 wt .-%. The proportion of adjusting agents, based on the total amount of ink, 0 to 1 wt .-%, preferably 0.1 to 0.5 wt .-%, amount. The auxiliaries also include other components, such as, for example, acetic acid, formic acid or n-methylpyrolidone or other polymers from the dye solution or paste used. With respect to substances which are suitable as component E, is supplemented, for example, on Ullmann's Encyclopaedia of Chemical Industry, Electronic Release 2008, Wiley Publishing, Chapter "Paints and Coatings", Section "Paint Additives" , referenced. Further, the materials which increase a refractive index of the ink are assigned to the additives and auxiliaries of the component E. For forming the optical waveguide, inks which do not contain pigments greater than 250 nm as the colorant are preferred since they have a negative effect on light conduction as scattering centers.

The features of the manufacturing method according to the invention, the method for verification and the device for verification have the same advantages as the corresponding features of the invention to the value and / or security document according to the invention.

12a . 12b . 12c schematically a verification of one with the substrate layer after 11 formed safety body; and

13 a plan view of a substrate layer, which is printed with a section-wise printed printing structure, wherein the sections have different colors.

In 1 is a substrate layer 1 schematically shown in plan view, to which a printing structure 2 is printed, which forms a light guide structure in a value and / or security document to be produced. The print structure 2 is made of a material, ie an ink or printing ink, which has a higher refractive index than the substrate layer 1 and other substrate layers adjacent to the print pattern 2 are arranged in a finished document body. The print structure 2 has a thread 3 on, in several more strands 4 branched. The strands 3 . 4 each start or end at one of the edges 5 the substrate layer forming a side surface of the formed document body after lamination. These areas of the printing structure adjoining the side surface 2 are called coupling areas 6 designated.

The areas between the strands 3 . 4 can also be printed, preferably with a transparent printing ink, which has a lower refractive index than the printing ink or ink with which the printing structure 2 is made. It is also possible between the other strands 4 form opaque separating elements, but preferably also by transparent material areas of the strands 4 are separated.

After the substrate layer 1 is printed with the print structure, this is with other substrate layers 7 - 10 to a substrate layer stack as shown in FIG 2 is shown. The same technical features are provided in all figures with identical reference numerals. The collation takes place in such a way that the printed surface 12 the substrate layer 1 is an inner substrate layer surface. This means that this substrate layer surface 12 is no top or bottom of the substrate layer stack.

In 3 the finished laminate is shown, which is the document body 13 of the value and / or security document. It is understood by those skilled in the art that any other security features in the document body forming the value and / or security document 13 can be incorporated as long as they have the photoconductive properties of the printing structure 2 , which is a light guide structure, do not affect. In 3 is clearly seen that the coupling areas 6 on side surfaces 14 which are a top 15 and a bottom 16 of the document body 13 connect.

In 4 is the document body 13 in an assistance device 20 to verify the value and / or security document. The assistant device 20 includes a guide 21 into which the document body 13 can be introduced so that the Lichtleitstruktur, ie the pressure structure 2 , relative to an excitation source 22 can be positioned defined. The excitation source 22 is a light source in the example shown. This can be, for example, a light emitting diode. Once the document body 13 in the lead 21 the assistant device 20 is positioned correctly, ie against a stop 23 is pushed, light is in the coupling area 6 of the strand 3 (see. 1 ) coupled and through the structure forming a Lichtleitstruktur print structure 2 to the coupling areas 6 the other strands 4 (see. 1 ) in the side surfaces 14 guided. It is understood by those skilled in the art that in other places of the side surfaces 14 a certain amount of light can escape, which is not passed through total reflection at the interfaces of the Lichtleitstruktur. However, the amount of light that is to the coupling areas 6 much larger, so that they can be perceived much brighter. Based on the resulting light emission pattern, the security and / or security document can be verified. Here, a number of coupling areas 6 or further strands 4 , a relative distance, an extension along the side surfaces 14 etc. are varied to encode an individualizing and / or personalizing information. A characteristic light emission pattern can be perceived by a simple visual inspection by a human. If the coded information, which represents, for example, a type of bar code, is to be evaluated, then a spatially resolving light detection unit is preferably used. This can for example comprise a CCD chip, which can determine a positioning and / or expansion of the coupling regions by means of an evaluation software and compare with an expected pattern.

In 5 is a plan view of another substrate layer 1' shown on a differently structured light structure 2 ' is printed. In this embodiment, the ink or ink constituting the conductive structure comprises a luminescent substance.

In 6 For example, the substrate layer stack formed by collation is analogous to that shown in FIG 2 shown schematically.

7 shows a side view of the resulting document body 13 , The decoupling areas are again clearly visible 6 in the side areas 14 of the document body 13 ,

In 8th the verification of the value and / or security document is shown schematically. About an excitation source 22 becomes, for example, UV light 24 through the upper substrate layers 7 . 8th in the light guide structure 2 ' , which is formed by the printing layer, irradiated. There, the luminescent substances are excited to luminescence. The light thereby coupled into the light guide structure partially emerges 25 through the top 15 or the bottom 16 because it is usually imitated by the luminescent substances isotropically in space. Thus, part of the light strikes the interface of the light guide structure at an acute angle and can leave it. A big part 26 However, the light hits the interface at an obtuse angle and becomes one of the coupling regions 6 directed. Therefore, they appear brighter than the remaining side surface 14 of the document body 13 , On the basis of the pattern, which is formed by the light emission and is referred to as a light emission pattern, a verification of the security document can be made.

In 9 a substrate layer stack is shown, which is another arrangement of the substrate layers 7 - 10 shows. In this arrangement is only a substrate layer 7 above with the light guiding structure 2 '' printed substrate layer 1'' arranged.

The resulting document body 13 is in 10 shown schematically.

In 11 is the top view of another substrate layer 1'' shown at the pressure structure 2 in three sections 2a . 2 B and 2c is printed. The sections 2a and 2c are printed with a color containing luminescent substances. The section 2 B On the other hand, it is printed with color that contains no luminescent substances.

In 12a to 12c is respectively the resulting document body 13 represented, which is excited locally at different positions by means of UV light. At a suggestion in the sections 2a and 2 B (see. 11 ) occurs as in 12a and 12c is shown, in each case a luminescence, ie a light extraction from the coupling regions 6 , on. This is due to the fact that the suggestion in the areas 2a and 2 B (see. 11 ) in each case has a luminescence result. When excitation in the center of the document body, which is an excitation of the section 2 B (see. 11 ) causes, however, occurs no luminescence, so that no light leakage from the coupling regions 6 can be observed.

In 13 is the top view of another substrate layer 1'''' shown in which the pressure structure in the sections 2a to 2f is printed. Here are the sections 2a to 2e at least two different colors, which are produced via colorants. For verification is over the coupling area 6 ' z. B. white light coupled. It results at the coupling areas 6 '' 6 ''' . 6 '''' . 6 ''''' . 6 ''''' at least two different color impressions. As a result, in addition to the position of the coupling regions in their color information can be encoded.

It is understood by those skilled in the art that only exemplary structuring of the printing structure or the light guide structure formed thereby are shown. Preferably, the substrate layer 1 . 1' . 1'' . 1''' . 1'''' and each directly to the printing structure 2 adjacent further substrate layer 7 formed of a transparent material. However, embodiments are also conceivable in which the immediately adjacent layer is opaque. It will be apparent to those skilled in the art that the structure of the document body formed as a laminate may vary greatly from the structure described herein. In particular, a number of the substrate layers used and a thickness of the substrate layers can vary greatly, in particular for the integration of electronic components, such. As chips, contact elements, antennas, displays and the like.
