Description

Die Erfindung betrifft ein beschichtetes Trägersubstrat, das beidseitig sowohl im Auf- als auch im Durchlicht betrachtet unterschiedliche farbige und/oder fluoreszierende Merkmale aufweist.The invention relates to a coated carrier substrate, which has different colored and / or fluorescent features on both sides viewed both in the incident and transmitted light.

Für eine Vielzahl von Anwendungen im Bereich der Sicherheitselemente aber auch im dekorativen Bereich, im Bereich der Verpackungsindustrie und dergleichen, ist es oft wünschenswert, dass ein Element, von beiden Seiten, ein typisches, eindeutiges aber optisch unterschiedliches Erscheinungsbild aufweist und zwar unabhängig davon ob das Element im Auf- oder im Durchlicht betrachtet wird.For a variety of applications in the field of security elements but also in the decorative field, in the packaging industry and the like, it is often desirable that an element, from both sides, a typical, unique but visually different appearance, regardless of whether the Element in the transmitted or transmitted light is considered.

Insbesondere im Bereich der Sicherheitsmerkmale für Datenträger, Wertdokumente und dergleichen tragen, neben anderen Sicherheitsmerkmalen solche eindeutigen typischen optischen Merkmale wesentlich zur Identifizierung bei.In particular, in the field of security features for data carriers, value documents and the like contribute, among other security features such unique typical optical features essential for identification.

Es sind eine Reihe von Kombinationen unterschiedlicher Sicherheitsmerkmale in einem Sicherheitsmerkmal bekannt beispielsweise maschinenlesbare Merkmale, kombiniert mit optischen farbigen, lumineszierenden (fluoreszierenden oder phosphoreszierenden) Merkmalen, Oberflächenstrukturen und dergleichen, wobei die Merkmale von unterschiedlichen Seiten betrachtet, unterschiedliche Erscheinungsbilder aufweisen können.There are a number of combinations of different security features in a security feature known, for example, machine-readable features, combined with optical colored, luminescent (fluorescent or phosphorescent) features, surface structures and the like, the features viewed from different sides, may have different appearances.

Insbesondere bei der Verwendung von farbigen oder fluoreszierenden Merkmalen, ist die Erzielung eindeutiger typischer optischer Erscheinungsbilder auf beiden Seiten des Elements nur sehr schwer zu realisieren.In particular, when using colored or fluorescent features, achieving unique, typical visual appearances on both sides of the element is very difficult to achieve.

Bei farbigen oder bei fluoreszierenden Merkmalen ist zwar bei auf jeder Seite unterschiedlichen farbigen oder fluoreszierenden Merkmalen im Auflicht jeweils die typische Farbe bzw. Fluoreszenzfarbe eindeutig sichtbar, bei der Betrachtung im Durchlicht jedoch entsteht durch subtraktive Farbmischung eine Mischfarbe bzw. bei Fluoreszenzfarben durch additive Farbmischung eine stark aufgehellte verweißlichte Fluoreszenz ohne typischen und zur eindeutigen Identifizierung notwendigen Fluoreszenzeffekt.In the case of colored or fluorescent features, although the typical color or fluorescence color is clearly visible in reflected light on each side, a mixed color is produced by subtractive color mixing or a strong color in the case of fluorescent colors by additive color mixing lightened, incandescent fluorescence without typical fluorescent effect necessary for unambiguous identification.

Dabei ist es unerheblich ob die unterschiedlichen Farben oder Fluoreszenzfarben auf unterschiedlichen Seiten des zumindest semitransparenten oder transparenten oder transluzenten Trägersubstrats aufgebracht sind oder auf einer Seite des Trägersubstrats.It is irrelevant whether the different colors or fluorescent colors are applied on different sides of the at least semitransparent or transparent or translucent carrier substrate or on one side of the carrier substrate.

Aus der EP 0 412 492 ist bekannt, bei Prägefolien insbesondere Heißprägefolien eine Zwischenschicht, die ein Metallicpigment enthält, einzubringen um so ein Durchscheinen eines Musters beim Betrachten eines zweiten Musters von der entgegengesetzten Seite zu verhindern. Diese Zwischenschicht ist opak und vollflächig aufgebracht.From the EP 0 412 492 It is known, for stamping foils, in particular hot stamping foils, to introduce an intermediate layer containing a metallic pigment so as to prevent a pattern from showing through when viewing a second pattern from the opposite side. This intermediate layer is opaque and applied over the entire surface.

GB-A-2338680 offenbart ein Substrat zur Verwendung als Sicherheitselement. GB-A-2338680 discloses a substrate for use as a security element.

Aufgabe der Erfindung war es daher einen Aufbau für ein beschichtetes Trägersubstrat bereitzustellen, dass von beiden Seiten typische unterschiedliche optische Eigenschaften aufweist.The object of the invention was therefore to provide a structure for a coated carrier substrate that has typical different optical properties from both sides.

Gegenstand der Erfindung ist daher ein beschichtetes Trägersubstrat, dadurch gekennzeichnet, dass es mindestens ein im Auf- und im Durchlicht erkennbares Sicherheitsmerkmal mit von beiden Seiten unterschiedlichen typischen Farboder Fluoreszenzmerkmalen aufweist, wobei die unterschiedlichen Farb- oder Fluoreszenzschichten durch eine lichtundurchlässige Schicht voneinander getrennt sind.The invention therefore relates to a coated carrier substrate, characterized in that it has at least one security feature recognizable in the incident and transmitted light with different color or fluorescence characteristics different from each other, the different color or fluorescence layers being separated from one another by an opaque layer.

Als Trägersubstrat kommen beispielsweise Trägerfolien vorzugsweise flexible transparente oder transluzente Kunststofffolien, beispielsweise aus Pl, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PSU, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM, ABS, PVC in Frage. Die Trägerfolien weisen vorzugsweise eine Dicke von 5 - 700 µm, bevorzugt 8 - 200 µm, besonders bevorzugt 12 - 50 µm auf.Carrier foils are preferably, for example, flexible transparent or translucent plastic foils, for example, from Pl, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PSU, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM. ABS, PVC in question. The carrier films preferably have a thickness of 5 to 700 .mu.m, preferably 8 to 200 .mu.m, more preferably 12 to 50 .mu.m.

Die Trägersubstrate können zusätzlich eine Lackschicht aufweisen, die unstrukturiert oder strukturiert, beispielsweise geprägt sein kann Die Lackschicht kann beispielsweise eine haftende Lackschicht oder eine releasefähige Transferlackschicht sein, sie kann durch Strahlung, beispielsweise UV-Strahlung, thermisch oder reaktiv vernetzt oder vemetzbar sein und zusätzliche Eigenschaften wie z.B. kratzfeste und/oder antistatische Ausrüstung oder chemische Beständigkeit besitzen. Geeignet sind sowohl wässrige als auch lösungsmittelhältige Lacksysteme, insbesondere auch Lacksysteme auf Basis PE - Acrylat, PET-Acrylat, Urethan-Acrylat, PVC, PMMA oder Epoxyacrylat.
Das Trägersubstrat kann ein- oder beidseitig mit einem Heiß- oder Kaltsiegelkleber oder einer Selbstklebebeschichtung versehen sein.The lacquer layer may be, for example, an adhesive lacquer layer or a release-transfer lacquer layer, it may be thermally or reactively crosslinked or crosslinkable by radiation, for example UV radiation, or be crosslinkable and additional properties such as scratch resistant and / or antistatic equipment or chemical resistance. Both aqueous and solvent-based coating systems are suitable, in particular coating systems based on PE acrylate, PET acrylate, urethane acrylate, PVC, PMMA or epoxy acrylate.
The carrier substrate may be provided on one or both sides with a hot or cold seal adhesive or a self-adhesive coating.

Die Oberfläche des Trägersubstrats kann strukturiert oder unstrukturiert sein, oder beispielsweise mit Mikro- oder Makrolinien geprägt sein, das heißt auf der Oberfläche können gegebenenfalls zwei- oder dreidimensionale Strukturen vorhanden sein.The surface of the carrier substrate may be structured or unstructured, or be embossed, for example, with micro- or macro-lines, that is to say two or three-dimensional structures may possibly be present on the surface.

Ferner kann das Trägersubstrat bereits partielle Farb- oder Lackschichten aufweisen.Furthermore, the carrier substrate may already have partial color or lacquer layers.

Auf das gegebenenfalls bereits partiell beschichtete oder bedruckte Trägersubstrat wird eine erste Farbschicht aufgebracht, wobei diese Schicht eine bestimmte Farbe aufweist und vorzugsweise eine fluoreszierende Farbschicht ist. Diese Schicht kann aber auch einen definierten Farbverlauf aufweisen.On the optionally already partially coated or printed carrier substrate, a first color layer is applied, this layer having a certain color and preferably a fluorescent Color layer is. However, this layer can also have a defined color gradient.

Anschließend wird auf diese Schicht die lichtundurchlässige Schicht aufgedruckt. Die die lichtundurchlässige Schicht bildende Druckfarbe kann lösemittelhaltig, lösemittelfrei und/oder wasserverdünnbar sein. Als Bindemittel kommen alle natürlichen und synthetischen Bindemittel in Frage. Die Druckfarbe ist pigmentiert, wobei als Pigmente TiO2 und/oder ZnS und/oder BaSO4 und/oder Al2O3 und/oder Kieselsäurederivate und/oder Kaolin und/oder Talkum und/oder Feldspate verwendet werden.
Die Druckfarbe für die lichtundurchlässige Schicht enthält vorzugsweise 5 - 40 Gew% an Pigmenten.
Die lichtundurchlässige Schicht kann aber auch beispielsweise eine metallisierte Schicht, die durch Aufdampfen von Metallen und/oder Metallverbindungen hergestellt wird, sein. Besonders geeignet dafür sind Metalle wie beispielsweise schwarz gefärbtes Aluminium (unstöchiometrisches AlxOy) und dergleichen.Subsequently, the opaque layer is printed on this layer. The ink forming the opaque layer can be solvent-based, solvent-free and / or water-dilutable. Suitable binders are all natural and synthetic binders. The printing ink is pigmented, the pigments used being TiO 2 and / or ZnS and / or BaSO 4 and / or Al 2 O 3 and / or silicic acid derivatives and / or kaolin and / or talc and / or feldspars.
The ink for the opaque layer preferably contains 5-40% by weight of pigments.
However, the opaque layer can also be, for example, a metallized layer which is produced by vapor deposition of metals and / or metal compounds. Particularly suitable for this are metals such as black-colored aluminum (unstoichiometric Al x O y ) and the like.

Auf diese lichtundurchlässige Schicht wird anschließend eine weitere von der ersten Farbschicht unterschiedliche Farbschicht bzw. fluoreszierende Farbschicht aufgebracht.Onto this opaque layer, another color layer or fluorescent color layer different from the first color layer is subsequently applied.

Die Farbschichten und die lichtundurchlässige Schicht können in jedem beliebigen bekannten Beschichtungsverfahren, wie beispielsweise einem Siebdruck-, Tiefdruck- Digital- oder Flexodruckverfahren, oder durch ein Walzenauftragsverfahren aufgebracht werden. Die Beschichtung kann dabei vollflächig oder partiell erfolgen, wobei in diesem Fall alle drei Schichten passergenau aufgebracht werden. Die lichtundurchlässige Schicht muss in jedem Fall in jenen Bereichen aufgebracht werden, in denen sowohl die erste als auch die zweite Farbschicht vorhanden sind und zu Identifizierung sichtbar sind.The color layers and the opaque layer may be applied by any known coating method, such as screen, gravure, digital or flexographic printing, or by a roll coating method. The coating can be carried out over the entire surface or partially, in which case all three layers are applied in register. The opaque layer must in any case be applied in those areas in which both the first and the second color layer are present and are visible for identification.

Durch die zwischen den Farbschichten situierte lichtundurchlässige Schicht wird insbesondere die bei der Betrachtung von bei Fluoreszenzfarben im Durchlicht auftretende additve Farbmischung, bzw. die bei anderen Farben auftretende subtraktive Farbmischung verhindert. Die Farben erscheinen dann auch im Durchlicht mit ihren typischen optischen Eigenschaften, also mit der reinen Farbe, bzw. dem typischen Fluoreszenzeffekt.By means of the opaque layer situated between the color layers, in particular the additive color mixture occurring when viewing fluorescence colors in transmitted light or the subtractive color mixture occurring in other colors is prevented. The colors then also appear in transmitted light with their typical optical properties, ie with the pure color or the typical fluorescence effect.

Gegebenenfalls können anschließend weitere funktionell und/oder dekorative Farb- oder Lackschichten partiell aufgebracht werden.
Diese Schichten können gleich oder unterschiedlich von den Schichten sein, die gegebenenfalls bereits partiell auf dem Trägersubstrat vorhanden sein können.Optionally, then further functional and / or decorative paint or varnish layers may be partially applied.
These layers may be the same or different from the layers, which may already be partially present on the carrier substrate.

Als solche Farb- bzw. Lackschichten können jeweils verschiedenste Zusammensetzungen verwendet werden. Die Zusammensetzung der einzelnen Schichten kann insbesondere nach deren Aufgabe variieren, also ob die einzelnen Schichten ausschließlich Dekorationszwecken dienen oder eine funktionelle Schicht sein sollen oder ob die Schicht sowohl eine Dekorationsals auch eine funktionelle Schicht sein soll.As such color or lacquer layers, a wide variety of compositions can be used in each case. The composition of the individual layers may in particular vary according to their purpose, that is to say whether the individual layers serve exclusively for decorative purposes or should be a functional layer or whether the layer should be both a decoration layer and a functional layer.

Die zu druckenden Schichten können pigmentiert oder nicht pigmentiert sein. Als Pigmente können alle bekannten Pigmente, wie beispielsweise Titandioxid, Zinksulfid, Kaolin, ATO, FTO, Aluminium, Chrom- und Siliciumoxide als auch farbige Pigmente verwendet werden. Dabei sind lösungsmittelhaltige Lacksysteme als auch System ohne Lösungsmittel verwendbar.
Als Bindemittel kommen verschiedene natürliche oder synthetische Bindemittel in Frage.The layers to be printed may be pigmented or unpigmented. As pigments, it is possible to use all known pigments, for example titanium dioxide, zinc sulfide, kaolin, ATO, FTO, aluminum, chromium oxides and silicon oxides, as well as colored pigments. In this case, solvent-based coating systems and systems without solvents can be used.
Suitable binders are various natural or synthetic binders.

Die funktionellen Schichten beispielsweise können bestimmte elektrische, magnetische, chemische, physikalische und auch optische Eigenschaften aufweisen.For example, the functional layers may have certain electrical, magnetic, chemical, physical and also optical properties.

Zur Einstellung elektrischer Eigenschaften, beispielsweise Leitfähigkeit können beispielsweise Graphit, Ruß, leitfähige organische oder anorganische Polymere. Metallpigmente (beispielsweise Kupfer, Aluminium, Silber, Gold, Eisen, Chrom und dergleichen), Metalllegierungen wie Kupfer-Zink oder Kupfer-Aluminium oder auch amorphe oder kristalline keramische Pigmente wie ITO und dergleichen zugegeben werden. Weiters können auch dotierte oder nicht dotierte Halbleiter wie beispielsweise Silicium, Germanium oder lonenleiter wie amorphe oder kristalline Metalloxide oder Metallsulfide als Zusatz verwendet werden. Ferner können zur Einstellung der elektrischen Eigenschaften der Schicht polare oder teilweise polare Verbindungen, wie Tenside oder unpolare Verbindungen wie Silikonadditive oder hygroskopische oder nicht hygroskopische Salze verwendet oder zugesetzt werden.To adjust electrical properties, such as conductivity, for example, graphite, carbon black, conductive organic or inorganic polymers. Metal pigments (for example, copper, aluminum, silver, gold, iron, chromium and the like), metal alloys such as copper-zinc or copper-aluminum or amorphous or crystalline ceramic pigments such as ITO and the like may be added. Furthermore, it is also possible to use doped or non-doped semiconductors, such as, for example, silicon, germanium or ionic conductors, such as amorphous or crystalline metal oxides or metal sulfides, as an additive. Furthermore, polar or partially polar compounds such as surfactants or nonpolar compounds such as silicone additives or hygroscopic or non-hygroscopic salts can be used or added to adjust the electrical properties of the layer.

Zur Einstellung der magnetischen Eigenschaften können paramagnetische, diamagnetische und auch ferromagnetische Stoffe, wie Eisen, Nickel und Cobalt oder deren Verbindungen oder Salze (beispielsweise Oxide oder Sulfide) verwendet werden.To adjust the magnetic properties, paramagnetic, diamagnetic and also ferromagnetic substances, such as iron, nickel and cobalt or their compounds or salts (for example oxides or sulfides) can be used.

Die optischen Eigenschaften einer gegebenenfalls vorhandenen partiellen Schicht lassen sich durch sichtbare Farbstoffe bzw. Pigmente, lumineszierende Farbstoffe bzw. Pigmente, die im sichtbaren, im UV-Bereich oder im IR-Bereich fluoreszieren bzw. phosphoreszieren, Effektpigmente, wie Flüssigkristalle, Perlglanz, Bronzen und/oder Multilayer-Farbumschlagpigmente und wärmeempfindliche Farben bzw. Pigmente beeinflussen. Diese sind in allen möglichen Kombinationen einsetzbar. Zusätzlich können auch phosphoreszierende Pigmente allein oder in Kombination mit anderen Farbstoffen und/oder Pigmenten eingesetzt werden.The optical properties of an optionally present partial layer can be visualized by visible dyes or pigments, luminescent dyes or pigments which fluoresce or phosphoresce in the visible, in the UV region or in the IR region, effect pigments such as liquid crystals, pearlescent, bronzes and / or multilayer color change pigments and heat-sensitive inks or pigments. These can be used in all possible combinations. In addition, phosphorescent pigments can also be used alone or in combination with other dyes and / or pigments.

Es können auch verschiedene Eigenschaften durch Zufügen verschiedener oben genannter Zusätze kombiniert werden. So ist es möglich angefärbte und/oder leitfähige Magnetpigmente zu verwenden. Dabei sind alle genannten leitfähigen Zusätze verwendbar.Various properties can also be combined by adding various additives mentioned above. Thus, it is possible to use colored and / or conductive magnetic pigments. All mentioned conductive additives can be used.

Speziell zum Anfärben von Magnetpigmenten lassen sich alle bekannten löslichen und nicht löslichen Farbstoffe bzw. Pigmente verwenden. So kann beispielsweise eine braune Magnetfarbe durch Zugabe von Metallen in ihrem Farbton metallisch, z.B. silbrig eingestellt werden.Especially for the dyeing of magnetic pigments it is possible to use all known soluble and non-soluble dyes or pigments. For example, a brown magnetic paint can be metallic, e.g., by adding metals in its hue, e.g. be set silvery.

Zum Drucken löslicher Schichten kann die verwendete Farbe bzw. der verwendete Farblack in einem Lösungsmittel, vorzugsweise in Wasser löslich sein, es kann jedoch auch eine in jedem beliebigen Lösungsmittel, beispielsweise in Alkohol, Estern und dergleichen lösliche Farbe verwendet werden. Die Farbe bzw. der Farblack können übliche Zusammensetzungen auf Basis von natürlichen oder künstlichen Makromolekülen sein. Die Farbe kann pigmentiert oder nicht pigmentiert sein. Als Pigmente können alle bekannten Pigmente verwendet werden. Besonders geeignet sind TiO2, ZnS, Kaolin und dergleichen.
Bei Verwendung einer löslichen Farbschicht kann diese gegebenenfalls nach Aufbringung einer weiteren Schicht im erfindungsgemäßen Verfahren durch ein geeignetes Lösungsmittel, das auf die Zusammensetzung der Farbschicht abgestimmt ist, entfernt werden, um Codierungen in Form von Zeichen und/oder Mustern jeder möglichen Art herstellen zu können.For printing soluble layers, the ink or lacquer used may be soluble in a solvent, preferably water, but a dye soluble in any solvent, for example in alcohol, esters and the like, may also be used. The color or the colored lacquer can be customary compositions based on natural or artificial macromolecules. The color may be pigmented or unpigmented. As pigments, all known pigments can be used. Particularly suitable are TiO 2 , ZnS, kaolin and the like.
If a soluble color layer is used, it may optionally be removed after application of another layer in the process according to the invention by a suitable solvent adapted to the composition of the color layer in order to be able to produce codings in the form of characters and / or patterns of any possible type.

Ferner können beispielsweise Isolatorschichten aufgebracht werden. Als Isolatoren sind beispielsweise organische Substanzen und deren Derivate und Verbindungen, beispielsweise Farb- und Lacksysteme, z.B. Epoxy-, Polyester-, Kolophonium-, Acrylat-, Alkyd-, Melamin-, PVA-, PVC-, Isocyanat-, Urethansysteme, die strahlungshärtend sein können, beispielsweise durch Wärme- oder UV-Strahlung, geeignet.Furthermore, for example, insulator layers can be applied. As insulators, for example, organic substances and their derivatives and compounds, for example, paint and varnish systems, e.g. Epoxy, polyester, rosin, acrylate, alkyd, melamine, PVA, PVC, isocyanate, urethane systems which may be radiation-curable, for example by heat or UV radiation.

Diese Schichten können durch bekannte Verfahren, beispielsweise durch Bedampfen, Sputtern, Drucken (beispielsweise Tief-, Flexo-, Sieb-, Digitaldruck) und dergleichen) , Sprühen, Galvanisieren und dergleichen aufgebracht werden. Die Dicke der funktionellen Schicht beträgt 0,001 bis 50 µm, vorzugsweise 0,1 bis 20 µm.These layers can be applied by known methods such as sputtering, sputtering, printing (e.g. gravure, flexo, screen, digital printing) and the like), spraying, electroplating and the like. The thickness of the functional layer is 0.001 to 50 μm, preferably 0.1 to 20 μm.

Anschließend wird die Farbschicht durch ein geeignetes Lösungsmittel, das auf die Zusammensetzung der Farbschicht abgestimmt ist, entfernt. Bevorzugt ist der Farbauftrag wasserlöslich. Gegebenenfalls kann die Ablösung durch mechanische Einwirkung unterstützt werden.Subsequently, the color layer is removed by a suitable solvent, which is adapted to the composition of the color layer. The application of paint is preferably water-soluble. Optionally, the separation can be supported by mechanical action.

Um das Anlösen der abgedeckten Farbschicht weiter zu verbessern kann auch vollflächig oder passergenau eine dünne pigmentierte Farbschicht oder eine reine Pigmentschicht aufgebracht werden, wobei die Dicke dieser Schicht etwa 0,01 - 5 µm beträgt.In order to further improve the dissolution of the covered ink layer, it is also possible to apply a thin pigmented ink layer or a pure pigment layer over the whole surface or register, the thickness of this layer being approximately 0.01-5 μm.

Durch das Ablösen des Farbauftrags mit den über dem Farbauftrag befindlichen Bereichen der funktionellen Schicht, wird das gewünschte Produkt erhaltenBy detaching the paint application with the areas of the functional layer above the paint application, the desired product is obtained

Gegebenenfalls kann die beschichtete Folie auch noch durch eine Schutzschicht geschützt werden oder beispielsweise durch Kaschieren oder dergleichen weiterveredelt werden.Optionally, the coated film can also be protected by a protective layer or further refined, for example by laminating or the like.

Das Trägersubstrat kann bei einseitiger Beschichtung nach der Anwendung entfernt werden oder am Produkt verbleiben. Dabei kann die Trägerfolie gegebenenfalls auf der nicht beschichteten Seite besonders ausgerüstet werden, beispielsweise kratzfest, antistatisch und dergleichen.The carrier substrate may be removed after application or remain on the product in one-sided coating. In this case, the carrier film may optionally be specially equipped on the uncoated side, for example, scratch-resistant, antistatic and the like.

In den Fig. 1 und 2 sind Beispiele für einen erfindungsgemäßen Aufbau dargestellt.In the Fig. 1 and 2 Examples of a construction according to the invention are shown.

Darin bedeuten 1 das Trägersubstrat, 2 die erste Farbschicht 3 die Zwischenschicht 4 die zweite Farbschicht, 5 und 6 jeweils eine weitere funktionelle Schicht und 7 eine Schutzlackschicht.1 is the carrier substrate, 2 is the first color layer 3, the intermediate layer 4 is the second color layer, 5 and 6 are each a further functional layer, and 7 is a protective lacquer layer.

Die erfindungsgemäßen beschichteten Trägersubstrate können als Sicherheitselemente in Datenträgern, insbesondere Wertdokumenten, wie Ausweisen, Karten, Banknoten, als Bauelemente und dekorative Elemente in der Architektur und in anderen technischen Bereichen und als Verpackungsmaterialien in der pharmazeutischen oder Lebensmittelindustrie verwendet werden.The coated carrier substrates according to the invention can be used as security elements in data carriers, in particular value documents, such as identity cards, cards, banknotes, as components and decorative elements in architecture and in other technical fields, and as packaging materials in the pharmaceutical or food industry.
