Definitions
- the invention relates to a security element for securing data carriers, valuable documents and the like, which has machine-readable security features, in particular magnetic features.
- a security document with a security element in the form of a thread or band made of transparent plastic material which has a metallic layer with recesses in the form of characters, patterns or the like, with a further magnetic layer being arranged above or below this metal layer in such a way that at least the legible recesses remain free.
- EP 1 871 616 B1 a security element with spatially resolved magnetic coding is known.
- the magnetic codes are applied in two partial layers on different sides of the carrier substrate simultaneously with transparent recesses in the form of patterns, characters, letters, geometric figures, lines, guilloches and the like, with the respective magnetic layers partially overlapping and with the magnetic codes being spatially resolved can be and in addition to the two codings in the carrier substrate level, a coding normal to the carrier substrate level is added.
- Security elements which have at least two magnetic materials, the magnetic materials having different coercive field strengths.
- the materials are applied and/or introduced onto and/or into the security element in such a way that their remanence is the same.
- a security element in particular for banknotes, security cards and the like, which comprises a first substrate which is at least partially opaque when viewed in transmitted light, with magnetic areas being applied to the substrate.
- the magnetic areas include at least two different magnetic areas that have different coercivity and whose residual magnetism can be the same or different.
- the magnetic areas are arranged in such a way that they generate at least three different codes.
- a security element that has a coating made of different materials, wherein a layer can be a coding magnetic layer that can be formed by materials of the same or different coercivity.
- a security element for securing documents of value which comprises coding with magnetic coding elements, the first coding element having a magnetic area with a first coercive field strength and the second coding element having a magnetic area with a second coercive field strength and a gap area.
- the security element described is designed as a transfer element which can be coated with a combination of several layers with different materials, the magnetic features having different coercivity and/or remanence and can be applied over the entire surface or partially next to each other, on top of each other or overlapping.
- the object of the invention was to provide a security element with machine-readable, in particular magnetic, security features, which has increased security against forgery, is easy to produce and enables clear identification.
- each magnetic area being made up of exactly one printing ink and the magnetic areas can either directly border one another or can be spaced apart from one another.
- the magnetic coding is carried out by mixing the at least two magnetic materials with different coercive field strengths in the printing ink that forms the magnetic areas and applying them with the same or different thickness to the security element. It is not possible according to the invention if only a single printing ink with a defined mixing ratio is used. This has the advantage of simple and cost-effective production while still maintaining a high level of safety, since when using a single printing ink, no production fluctuations can have an influence compared to printing several printing colors on top of each other. In addition, the same printing ink can be used to feed multiple printing cylinders. The different signal strengths are created solely by the different thicknesses with which the printing ink is applied.
- the two magnetic materials are preferably a material with a high coercivity and a material with a low coercivity, with a magnetic material of high coercivity in this context including materials with > 1500 Oe, and a material with a lower one Coercive field strength materials ⁇ 500 Oe understood.
- the magnetic materials are preferably chosen so that they do not influence each other when magnetized. Since a 3 times stronger magnetic field is usually used for each magnetic material when magnetizing, the difference in the coercive field strength of the magnetic materials must be chosen accordingly.
- the invention provides that at least two printing colors are used
- magnetic areas adjacent to one another are constructed using different printing inks.
- the magnetic areas, which are formed by the at least one printing ink are applied at a distance from one another, but it can also be advantageous to apply two or more, identical or different printing inks of different thicknesses directly adjacent to one another in the lateral direction, so that one Magnetic area group is created.
- a plurality of magnetic area groups can be arranged on the carrier substrate at a distance from one another, preferably at the same distance from one another.
- the printing inks of a magnetic area group have different thicknesses, the thicknesses preferably increasing or decreasing from one side of the magnetic area group to the opposite side.
- the printing ink which contains a mixture of the at least two magnetic materials with different coercive field strengths, is applied at least partially to a carrier substrate.
- the carrier substrates are, for example, transparent carrier films, preferably flexible plastic films, for example made of polyimide (PI), polypropylene (PP), monoaxially oriented polypropylene (MOPP), biaxially oriented polypropylene (BOPP), polyethylene (PE), polyphenylene sulfide (PPS), polyether ether ketone (PEEK ) Polyetherketone (PEK), polyethyleneimide (PEI), polysulfone (PSU), polyaryletherketone (PAEK), polyethylene naphthalate (PEN), liquid crystalline polymers (LCP), polyester, polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polyamide (PA), polycarbonate (PC), cycloolefin copolymers (COC), polyoxymethylene (POM), acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC) ethylene tetrafluoroethylene (ETFE), polyte
- the carrier films preferably have a thickness of 5 - 700 ⁇ m, preferably 5 - 200 ⁇ m, particularly preferably 5 - 50 ⁇ m.
- metal foils for example Al, Cu, Sn, Ni, Fe or stainless steel foils with a thickness of 5 - 200 ⁇ m, preferably 10 to 80 ⁇ m, particularly preferably 20 - 50 ⁇ m, can also serve as the carrier substrate.
- the films can also be surface-treated, coated or laminated, for example with plastics or painted.
- cellulose-free or cellulose-containing paper, thermoactivatable paper or composites with paper for example composites with plastics with a basis weight of 20 - 500 g/m 2 , preferably 40 - 200 g/m 2 , can also be used as carrier substrates.
- the security features according to the invention can be applied to the carrier substrate in order to form a security element.
- This security element can then be assembled and at least partially embedded as a strip, thread or patch in a data carrier or a document of value or applied to it.
- the security element is also possible to design the security element as a transfer element, whereby the carrier substrate can be removed after application to the data carrier or the document of value.
- the security features can also be generated directly on the data carrier or the valuable document by at least partially printing the color of at least two magnetic materials with different coercive field strengths at a predetermined location on the data carrier or valuable document.
- a printing ink which contains at least two magnetic materials with different coercivity.
- the mixing ratio of the magnetic materials with different coercive field strengths is set in a defined manner.
- the mixing ratio between a magnetic material with high coercivity and a magnetic material with low coercivity can be between 20:1 to 1:20, preferably 10:1 to 1:10, particularly preferably 5:1 to 1:5.
- the mixing ratio and thus the printing ink can be the same for all magnetic areas of the security element.
- the ratio of the different magnetic materials remains exactly constant during printing, regardless of the thickness of the printing inks applied. If printing inks of different thicknesses are applied, magnetic areas with different remanence are created with the same ratio of magnetic materials.
- two or more printing inks are used, with the mixing ratios of the magnetic materials in the printing inks being different.
- magnetic areas in addition to the magnetic areas formed from a printing ink with a mixture of two or more magnetic materials with different coercive field strengths, magnetic areas can be provided on the security element which consist only of magnetic material with low or only of magnetic material with high coercivity. In this case, either areas of magnetic material of low coercivity or areas of magnetic material of high coercivity are provided on the security element, preferably next to the magnetic areas formed from a printing ink with a mixture of two or more magnetic materials with different coercivity.
- the security element can have further layers with security features.
- an opaque layer in the form of a reflective layer or a print layer for example a colored, black, or white print layer, which can be applied over the entire area or partially, can be provided on the carrier substrate below and/or above the magnetic layer areas.
- a reflective layer is understood to mean, for example, a metallic layer made of Al, Cu, Ag, Au, Pd, Pt, Sn, In or their alloys and the like, which are applied by PVD or CVD processes, by sputtering, electron beam evaporation or the like .
- a reflective layer is also understood to mean, for example, a layer that appears metallic, such as a lacquer or printing ink layer that contains metallic pigments or flakes, or pigments or flakes made of metal compounds, such as metal oxides.

Aufgabe der Erfindung war es ein Sicherheitselement mit maschinenlesbaren, insbesondere magnetischen Sicherheitsmerkmalen bereitzustellen, das eine erhöhte Fälschungssicherheit aufweist, einfach herzustellen ist und eine eindeutige Identifikation ermöglicht.The object of the invention was to provide a security element with machine-readable, in particular magnetic, security features, which has increased security against forgery, is easy to produce and enables clear identification.
Gegenstand der Erfindung ist daher das in Anspruch 1 definierte Sicherheitselement.The subject of the invention is therefore the security element defined in
Durch das Aufbringen der zumindest einen Druckfarbe in unterschiedlichen Bereichen der Trägerfolie werden auf dieser verschiedene Magnetbereiche ausgebildet, wobei jeder Magnetbereich durch genau eine Druckfarbe aufgebaut ist und die Magnetbereiche entweder unmittelbar aneinander grenzen können oder zueinander beabstandet sein können.By applying the at least one printing ink in different areas of the carrier film, different magnetic areas are formed on it, each magnetic area being made up of exactly one printing ink and the magnetic areas can either directly border one another or can be spaced apart from one another.
Durch den Einsatz eines definierten Mischungsverhältnisses, ist es möglich eine eindeutige, schwer fälschbare magnetische Codierung zu erzeugen. Dabei ist es nicht nötig, dass die Anordnung der Magnetbereiche eine magnetische Codierung bildet.By using a defined mixing ratio, it is possible to create a unique, difficult-to-forge magnetic coding. It is not necessary for the arrangement of the magnetic areas to form a magnetic coding.
Die magnetische Codierung erfolgt durch die Mischung der mindestens zwei magnetischen Materialien unterschiedlicher Koerzitivfeldstärke in der Druckfarbe, die die Magnetbereiche bildet, und deren Aufbringung mit gleicher oder unterschiedlicher Dicke auf dem Sicherheitselement. Nicht erfindungsgemäß ist es möglich, wenn lediglich eine einzige Druckfarbe mit definiertem Mischungsverhältnis zum Einsatz kommt. Dies hat den Vorteil der einfachen und kostengünstigen Herstellung bei dennoch hoher Sicherheit, da bei Verwendung einer einzigen Druckfarbe keine Produktionsschwankungen verglichen mit dem Übereinanderdrucken von mehreren Druckfarben Einfluss nehmen können. Darüberhinaus kann die gleiche Druckfarbe zur Speisung mehrerer Durckzylinder verwendet werden. Die verschiedenen Signalstärken wird ausschließlich durch die verschiedene Dicken erzeugt, mit welchen die Druckfarbe aufgetragen wird.The magnetic coding is carried out by mixing the at least two magnetic materials with different coercive field strengths in the printing ink that forms the magnetic areas and applying them with the same or different thickness to the security element. It is not possible according to the invention if only a single printing ink with a defined mixing ratio is used. This has the advantage of simple and cost-effective production while still maintaining a high level of safety, since when using a single printing ink, no production fluctuations can have an influence compared to printing several printing colors on top of each other. In addition, the same printing ink can be used to feed multiple printing cylinders. The different signal strengths are created solely by the different thicknesses with which the printing ink is applied.
Bei den beiden magnetischen Materialien handelt es sich bevorzugt um ein Material mit hoher und ein Material mit niedriger Koerzitivfeldstärke, wobei unter einem magnetischen Material hoher Koerzitivfeldstärke in diesem Zusammenhang Materialien mit > 1500 Oe, unter einem Material niedriger Koerzitivfeldstärke Materialien < 500 Oe verstanden. Die magnetischen Materialien werden vorzugsweise so gewählt, dass sie sich beim Aufmagnetisieren gegenseitig nicht beeinflussen. Da üblicherweise beim Aufmagnetisieren ein 3-fach stärkeres magnetisches Feld für jedes magnetische Material verwendet wird, ist der Unterschied in der Koerzitivfeldstärke der magnetischen Materialien entsprechend zu wählen.The two magnetic materials are preferably a material with a high coercivity and a material with a low coercivity, with a magnetic material of high coercivity in this context including materials with > 1500 Oe, and a material with a lower one Coercive field strength materials < 500 Oe understood. The magnetic materials are preferably chosen so that they do not influence each other when magnetized. Since a 3 times stronger magnetic field is usually used for each magnetic material when magnetizing, the difference in the coercive field strength of the magnetic materials must be chosen accordingly.
Zur Verbesserung der Sicherheit ist erfindungsgemäß vorgesehen, dass zumindest zwei Druckfarben zumTo improve security, the invention provides that at least two printing colors are used

In einer Ausführungsvariante der Erfindung ist es vorgesehen, dass zueinander benachbarte Magnetbereiche durch unterschiedliche Druckfarben aufgebaut sind.In one embodiment variant of the invention it is provided that magnetic areas adjacent to one another are constructed using different printing inks.
In einer weiteren Ausführungsvariante der Erfindung sind die Magnetbereiche, die durch die mindestens eine Druckfarbe gebildet werden, voneinander beabstandet aufgebracht, es kann aber auch vorteilhaft sein zwei oder mehrere, gleiche oder unterschiedliche Druckfarben unterschiedlicher Dicke in lateraler Richtung direkt aneinandergrenzend aufzubringen, so dass dadurch eine Magnetbereichsgruppe entsteht. Mehrere Magnetbereichsgruppen können dabei zueinander beabstandet, vorzugsweise zueinander gleich beabstandet auf dem Trägersubstrat angeordnet sein.In a further embodiment variant of the invention, the magnetic areas, which are formed by the at least one printing ink, are applied at a distance from one another, but it can also be advantageous to apply two or more, identical or different printing inks of different thicknesses directly adjacent to one another in the lateral direction, so that one Magnetic area group is created. A plurality of magnetic area groups can be arranged on the carrier substrate at a distance from one another, preferably at the same distance from one another.
Dabei kann es weiters vorgesehen sein, dass die Druckfarben einer Magnetbereichsgruppe unterschiedliche Dicken aufweisen, wobei die Dicken vorzugsweise von einer Seite der Magnetbereichsgruppe zur gegenüberliegenden Seite hin zu- bzw. abnehmend verlaufen.It can further be provided that the printing inks of a magnetic area group have different thicknesses, the thicknesses preferably increasing or decreasing from one side of the magnetic area group to the opposite side.

In einer weiteren Ausführungsform können zusätzlich zu den Magnetbereichen gebildet aus einer Druckfarbe mit einer Mischung aus zwei oder mehreren magnetischen Materialien mit unterschiedlicher Koerzitivfeldstärke auf dem Sicherheitselement Magnetbereiche vorgesehen sein, die nur mit magnetischem Material mit niedriger oder nur aus magnetischem Material mit hoher Koerzitivfeldstärke bestehen. Dabei sind auf dem Sicherheitselement vorzugsweise neben den Magnetbereichen gebildet aus einer Druckfarbe mit einer Mischung aus zwei oder mehreren magnetischen Materialien mit unterschiedlicher Koerzitivfeldstärke entweder Bereiche aus magnetischem Material niedriger Koerzitivfeldstärke oder Bereiche aus magnetischem Material hoher Koerzitivfeldstärke vorgesehen.In a further embodiment, in addition to the magnetic areas formed from a printing ink with a mixture of two or more magnetic materials with different coercive field strengths, magnetic areas can be provided on the security element which consist only of magnetic material with low or only of magnetic material with high coercivity. In this case, either areas of magnetic material of low coercivity or areas of magnetic material of high coercivity are provided on the security element, preferably next to the magnetic areas formed from a printing ink with a mixture of two or more magnetic materials with different coercivity.
Das Sicherheitselement kann weitere Schichten mit Sicherheitsmerkmalen aufweisen.The security element can have further layers with security features.
So kann beispielsweise auf dem Trägersubstrat unter und/oder über den Magnetschichtbereichen eine opake Schicht in Form einer reflektierenden Schicht oder einer Druckschicht beispielsweise einer farbigen, schwarzen, oder weißen Druckschicht vorgesehen werden, die vollflächig oder partiell aufgebracht werden kann.For example, an opaque layer in the form of a reflective layer or a print layer, for example a colored, black, or white print layer, which can be applied over the entire area or partially, can be provided on the carrier substrate below and/or above the magnetic layer areas.
Unter einer reflektierenden Schicht wird in diesem Zusammenhang beispielsweise eine metallische Schicht aus Al, Cu, Ag, Au, Pd, Pt, Sn, In oder deren Legierungen und dergleichen verstanden, die durch PVD oder CVD Verfahren, durch Sputter, Elektronenstrahlverdampfung oder dergleichen aufgebracht sein. Unter einer reflektierenden Schicht wird beispielsweise auch eine metallisch erscheinende Schicht verstanden wie beispielsweise eine Lack- oder Druckfarbenschicht, die metallische Pigmente oder Flakes, oder Pigmente oder Flakes aus Metallverbindungen, wie beispielsweise Metalloxiden, enthält. Diese Schichten werden vorzugsweise durch bekannte Druckverfahren, durch Aufrakeln oder Aufstreichen aufgebracht.In this context, a reflective layer is understood to mean, for example, a metallic layer made of Al, Cu, Ag, Au, Pd, Pt, Sn, In or their alloys and the like, which are applied by PVD or CVD processes, by sputtering, electron beam evaporation or the like . A reflective layer is also understood to mean, for example, a layer that appears metallic, such as a lacquer or printing ink layer that contains metallic pigments or flakes, or pigments or flakes made of metal compounds, such as metal oxides. These layers are preferably applied using known printing processes, by doctoring or brushing.
Darüberhinaus kann es sich bei der reflektierenden Schicht auch um eine HRI (High Refractive Index) Schicht handeln, also beispielsweise um eine Druckschicht in Form einer Lackschicht oder einer Farbe mit hohem Brechungsindex.In addition, the reflective layer can also be an HRI (High Refractive Index) layer, for example a print layer in the form of a lacquer layer or a paint with a high refractive index.
Eine partiell aufgebrachte reflektierende Schicht bzw. eine Druckschicht kann vorzugsweise Aussparungen in Form von Buchstaben, Zahlen, Mustern, Zeichen, Symbolen, Linien und dergleichen aufweisen.A partially applied reflective layer or a printing layer can preferably have recesses in the form of letters, numbers, patterns, characters, symbols, lines and the like.
Die Aussparungen in der reflektierenden Schicht sind dabei vorzugsweise so angeordnet, dass sie in den magnetschichtfreien Bereichen liegen. Dadurch werden einerseits die Magnetschichtbereiche visuell abgedeckt, sodass sie auch bei Betrachtung im Durchlicht nicht erkennbar sind, andererseits entsteht durch die im Durchlicht erkennbaren Aussparungen in der metallischen bzw. metallisch erscheinenden Schicht bzw. der Druckschicht ein zusätzliches Sicherheitsmerkmal.The recesses in the reflective layer are preferably arranged so that they lie in the areas free of the magnetic layer. As a result, on the one hand, the magnetic layer areas are visually covered so that they cannot be seen even when viewed in transmitted light, and on the other hand, the recesses in the metallic or metallic-appearing layer or the print layer that can be seen in transmitted light create an additional security feature.
Eine derartige reflektierende Schicht kann alternativ auf der den Magnetbereichen gegenüberliegenden Seite das Trägersubstrats oder auf beiden Seiten des Trägersubstrats vorgesehen sein.Such a reflective layer can alternatively be provided on the side of the carrier substrate opposite the magnetic regions or on both sides of the carrier substrate.
Für den Fall, dass die reflektierende Schicht auf derselben Seite des Trägersubstrats unter und/oder über den Magnetbereichen vorgesehen ist, kann es zweckmäßig sein, zwischen dieser Schicht und den Magnetbereichen eine Schutzschicht vorzusehen um eine gegenseitige Beeinflussung der der magnetischen Schicht und der metallischen Schicht zu verhindern. Durch die Schutzschicht werden beispielsweise Korrosionserscheinungen, insbesondere wenn das Sicherheitselement Feuchtigkeit ausgesetzt ist, verhindert, insbesondere wenn die Schicht metallisch ist oder metallische Pigmente oder Flakes beinhaltet.In the event that the reflective layer is provided on the same side of the carrier substrate below and/or above the magnetic areas, it may be expedient to provide a protective layer between this layer and the magnetic areas in order to prevent the magnetic layer and the metallic layer from influencing each other impede. The protective layer prevents, for example, signs of corrosion, particularly when the security element is exposed to moisture, particularly when the layer is metallic or contains metallic pigments or flakes.
Diese Schutzschicht kann als dünne Folie ausgeführt sein, aber auch als Schutzlackschicht.This protective layer can be designed as a thin film, but also as a protective lacquer layer.
Ferner können auf dem Trägersubstrat oder im Schichtaufbau auch optisch variable Sicherheitsmerkmale vorliegen, beispielsweise diffraktive Strukturen, wie Oberflächenreliefs, Hologramme, Beugungsgitter und dergleichen, oder auch Schichten, die einen blickwinkelabhängigen Farbwechseleffekt aufweisen. Derartige Sicherheitsmerkmale mit blickwinkelabhängigem Farbwechseleffekten werden beispielsweise durch Dünnschichtelemente, die eine Reflexionsschicht, eine dielektrischen Abstandsschicht und eine Absorberschicht aufweisen, oder durch cholesterische Flüssigkeitskristallschichten kombiniert mit einer dunklen, vorzugsweise schwarzen Druckschicht oder Metallisierung gebildet. Es können aber auch Druckschichten mit Interferenzpigmenten oder flüssigkristallinen Pigmenten zur Herstellung einer Schicht mit blickwinkelabhängigem Farbwechseleffekt verwendet werden.Furthermore, optically variable security features can also be present on the carrier substrate or in the layer structure, for example diffractive structures such as surface reliefs, holograms, diffraction gratings and the like, or layers that have a color change effect depending on the viewing angle. Such security features with viewing angle-dependent color change effects are formed, for example, by thin-film elements that have a reflection layer, a dielectric spacer layer and an absorber layer, or by cholesteric liquid crystal layers combined with a dark, preferably black, printed layer or metallization. However, printing layers with interference pigments or liquid crystalline pigments can also be used to produce a layer with a color change effect dependent on the viewing angle.
Ferner kann das Sicherheitselement ggf. weitere farbige, schwarze, graue oder weiße Druckschichten aufweisen.Furthermore, the security element can optionally have further colored, black, gray or white print layers.
Alle diese Sicherheitsmerkmale können vollflächig oder partiell auf einer oder beiden Seiten des Trägersubstrat aufgebracht werden. Dabei können die Sicherheitsmerkmale register- und/oder passergenau, beispielsweise zu den Magnetbereichen aufgebracht werden.All of these security features can be applied over the entire surface or partially on one or both sides of the carrier substrate. They can do this Security features are applied in register and/or register accuracy, for example to the magnetic areas.
Unter dem Begriff registergenau bzw. passergenau wird eine definierte Position der Merkmale zueinander verstanden.The term register-accurate or register-accurate means a defined position of the features relative to one another.
Diese Sicherheitsmerkmale können auch derart aufgebracht werden, dass sie zumindest teilweise in den magnetschichtfreien Bereichen liegen bzw. diese zumindest teilweise verdecken.These security features can also be applied in such a way that they lie at least partially in the areas free of magnetic layers or at least partially cover them.
Die weiteren Sicherheitsmerkmale können auch auf einem zweiten Trägersubstrat bereitgestellt werden und durch Laminieren oder Kaschieren mit dem Schichtaufbau auf dem die Magnetbereiche liegen, verbunden werden.The further security features can also be provided on a second carrier substrate and connected to the layer structure on which the magnetic areas lie by laminating or covering.
Gegebenenfalls kann dann das zweite Trägersubstrat abgezogen werden. Zweckmäßigerweise kann das Sicherheitselement ein- und/oder beidseitig mit einer Schutzlackschicht versehen werden um die auf dem Sicherheitselement vorhandenen Sicherheitsmerkmale gegen mechanische, physikalische und/oder chemische Einflüsse zu schützen.If necessary, the second carrier substrate can then be removed. The security element can expediently be provided with a protective lacquer layer on one and/or both sides in order to protect the security features present on the security element against mechanical, physical and/or chemical influences.
Die Schutzlackschicht kann beispielsweise auf Basis von Nitrocellulose, Acrylaten und deren Copolymeren, Polyamiden und deren Copolymeren Polyvinylchloriden und deren Copolymeren aufgebaut sein oder aus einem vernetzenden Lack bestehen.The protective lacquer layer can, for example, be based on nitrocellulose, acrylates and their copolymers, polyamides and their copolymers, polyvinyl chlorides and their copolymers or consist of a cross-linking lacquer.
Ferner kann das Sicherheitselement ein- oder beidseitig mit einer Kleberschicht versehen werden, um eine Festlegung auf oder in einem Datenträger oder Wertdokumente zu ermöglichen. Diese Kleberschicht kann entweder in Form einer Heißsiegel-, Kaltsiegel- oder Selbstklebebeschichtung ausgeführt sein.Furthermore, the security element can be provided with an adhesive layer on one or both sides in order to enable attachment to or in a data carrier or valuable documents. This adhesive layer can be in the form of either a heat seal, cold seal or self-adhesive coating.
Die Schutzlackschicht und/oder die Kleberschicht können auch pigmentiert sein, wobei als Pigmente alle bekannten Pigmente oder Farbstoffe, beispielsweise TiO2, ZnS, Kaolin, ATO, FTO, Aluminium, Chrom- und Siliziumoxide oder beispielsweise organische Pigmente wie Phthalocyaninblau, i-Indolidgelb, Dioxazinviolett und dergleichen verwendet werden können. Ferner können lumineszierende Farbstoffe bzw. Pigmente, die im sichtbaren, im UV-Bereich oder im IR-Bereich fluoreszieren bzw. phosphoreszieren, Effektpigmente wie Flüssigkeitskristalle, Perlglanz, Bronzen und/oder Multilayer-Farbumschlagpigmente und wärmeempfindliche Farben bzw. Pigmente zugegeben werden. Diese sind in allen möglichen Kombinationen einsetzbar. Zusätzlich können auch lumineszierende Pigmente allein oder in Kombination mit anderen Farbstoffen und/oder Pigmenten eingesetzt werden.The protective lacquer layer and/or the adhesive layer can also be pigmented, the pigments being all known pigments or dyes, For example, TiO 2 , ZnS, kaolin, ATO, FTO, aluminum, chromium and silicon oxides or, for example, organic pigments such as phthalocyanine blue, i-indolide yellow, dioxazine violet and the like can be used. Furthermore, luminescent dyes or pigments that fluoresce or phosphorescent in the visible, UV or IR range, effect pigments such as liquid crystals, pearlescent, bronzes and/or multilayer color changing pigments and heat-sensitive colors or pigments can be added. These can be used in all possible combinations. In addition, luminescent pigments can also be used alone or in combination with other dyes and/or pigments.
Das Sicherheitselement kann auch als Transferelement ausgeführt sein, wobei nach der Aufbringung des Sicherheitselements auf einen Datenträger oder ein Wertdokument das Trägersubstrat abgezogen werden kann.The security element can also be designed as a transfer element, whereby the carrier substrate can be removed after the security element has been applied to a data carrier or a document of value.
Zur Erleichterung des Abziehens des Trägersubstrat kann dabei auf dem Trägersubstrat und unter dem auf dem Trägersubstrat vorhandenem Schichtaufbau eine Releaseschicht vorgesehen sein.To make it easier to remove the carrier substrate, a release layer can be provided on the carrier substrate and under the layer structure present on the carrier substrate.
