Description
Die Erfindung betrifft ein Sicherheitselement für Wertpapiere oder Sicherheitspapiere, wobei das Sicherheitselement mit zumindest einem ersten Bereich mit ersten Strukturen ausgebildet ist, welche ersten Strukturen eine erste Information in unterschiedliche Raumbereiche reflektieren, sodass für einen Betrachter bei entsprechender Bewegung einer Lichtquelle und/oder bei Veränderung eines Beobachtungswinkels ein Bewegungsbild entsteht, wobei bei Bewegung der Lichtquelle und/oder Veränderung des Beobachtungswinkels gleichzeitig eine Bewegung der ersten Information entsteht. Die Erfindung betrifft auch ein Verfahren zur Herstellung eines Sicherheitselements.The invention relates to a security element for securities or security papers, wherein the security element is formed with at least one first area with first structures, which first structures reflect a first piece of information in different spatial areas, so that for a viewer with a corresponding movement of a light source and/or with a change in a Observation angle creates a moving image, with movement of the light source and / or change in the viewing angle at the same time a movement of the first information. The invention also relates to a method for producing a security element.
Sicherheitselemente der eingangsgenannten Art werden üblicherweise verwendet um die Fälschungssicherheit von Wertpapieren oder Sicherheitspapieren, wie Banknoten, Ausweise, Kreditkarten, Bankomatkarten, Tickets etc. zu erhöhen.Security elements of the type mentioned at the outset are usually used in order to increase the protection against counterfeiting of securities or security papers, such as banknotes, identity cards, credit cards, ATM cards, tickets, etc.
Aufgabe der vorliegenden Erfindung ist es, ein Sicherheitselement mit erhöhter Fälschungssicherheit zu schaffen.The object of the present invention is to create a security element with increased security against forgery.
Diese Aufgabe wird durch ein Sicherheitselement eingangs genannter Art erfindungsgemäß dadurch gelöst, dass das Sicherheitselement mit zumindest einem zweiten Bereich mit zweiten Strukturen ausgebildet ist, welche zweiten Strukturen eine statische und/oder blickwinkelunabhängige zweite Information wiedergeben.This object is achieved according to the invention by a security element of the type mentioned at the outset in that the security element is formed with at least one second area with second structures, which second structures reproduce static and/or viewing-angle-independent second information.
Durch die erfindungsgemäße Lösung wird durch Kombination zweier Technologien bzw. zweier verschiedenartiger Sicherheitsmerkmale die Fälschungssicherheit von Sicherheitselementen für Wertpapiere oder Sicherheitspapiere wesentlich erhöht. Die Verbindung von Strukturen, welche ein Bewegungsbild erzeugen mit statischen und/oder blickwinkelunabhängigen Merkmalen ermöglicht ein hohes Maß an Individualisierbarkeit, respektive eine große Vielfalt an Gestaltungsmöglichkeiten. Damit einher geht eine signifikante Erhöhung der Fälschungssicherheit.With the solution according to the invention, the counterfeit protection of security elements for securities or security papers is significantly increased by combining two technologies or two different types of security features. The combination of structures that create a moving picture with static and/or viewing angle-independent features enables a high degree of individualization, or a large variety of design options. This is accompanied by a significant increase in protection against counterfeiting.
Gemäß einer vorteilhaften Weiterbildung kann vorgesehen sein, dass die ersten Strukturen als diffraktive Strukturen, als Mikrospiegel, als strahlenoptisch wirksame Facetten oder als achromatische, reflektierende Strukturen ausgebildet sind.According to an advantageous development, it can be provided that the first structures are designed as diffractive structures, as micromirrors, as facets that have an optical effect on radiation or as achromatic, reflecting structures.
Die Ausbildung der ersten Strukturen als diffraktive Strukturen ist beispielsweise aus der
Entsprechend einer weiteren Ausbildung kann es von Vorteil sein, dass die zweiten Strukturen durch diffus streuende Strukturen gebildet sind. Bevorzugt können die zweiten Strukturen durch diffus streuende Strukturen mit einer Größe von 1 µm bis 100 µm gebildet sein. Die Ausbildung der zweiten Strukturen als diffus streuende Strukturen ist der Fachwelt beispielsweise aus der
Des Weiteren kann es zweckmäßig sein, wenn der erste Bereich den zweiten Bereich zumindest abschnittsweise umgibt. Dadurch können vielfältige Designs realisiert werden. An dieser Stelle sei ausdrücklich darauf hingewiesen, dass die Bereiche in einzelne Teilbereiche ausgebildet sind. So kann beispielsweise der zweite Bereich eine Mehrzahl an Teilbereichen umfassen, welche von dem ersten Bereich zumindest partiell umgeben sein können. Dabei kann es auch sein, dass der erste Bereich den zweiten Bereich zumindest abschnittsweise umgibt, wobei zwischen den beiden Bereichen ein Abstand vorgesehen sein kann, durch welchen die beiden Bereiche zueinander distanziert sind. In einem solchen Distanzbereich kann beispielsweise auch ein weiterer Bereich mit einem dem Fachmann bekannten Sicherheitsmerkmal ausgebildet sein.Furthermore, it can be expedient if the first area surrounds the second area at least in sections. This allows a variety of designs to be realized. At this point it should be expressly pointed out that the areas are formed into individual partial areas. For example, the second area can include a plurality of partial areas, which can be at least partially surrounded by the first area. It can also be the case that the first area surrounds the second area at least in sections, it being possible for a distance to be provided between the two areas, by which the two areas are distanced from one another. A further area with a security feature known to the person skilled in the art can also be formed in such a distance area, for example.
Ferner kann vorgesehen sein, dass die erste Information und/oder die zweite Information als Buchstabe, Zahl, Zeichen, Symbol oder Teil eines Bildes oder Musters ausgebildet ist.Furthermore, it can be provided that the first piece of information and/or the second piece of information is in the form of a letter, number, character, symbol or part of an image or pattern.
Darüber hinaus kann vorgesehen sein, dass es eine Trägerschicht aus Kunststoff, insbesondere aus einem lichtdurchlässigen und/oder thermoplastischen Kunststoff, aufweist, wobei die Trägerschicht bevorzugt zumindest eines der Materialien aus der Gruppe Polyimid (PI), Polypropylen (PP), monoaxial orientiertem Polypropylen (MOPP), biaxial orientierten Polypropylen (BOPP), Polyethylen (PE), Polyphenylensulfid (PPS), Polyetheretherketon, (PEEK) Polyetherketon (PEK), Polyethylenimid (PEI), Polysulfon (PSU), Polyaryletherketon (PAEK), Polyethylennaphthalat (PEN), flüssigkristalline Polymere (LCP), Polyester, Polybutylentereph-thalat (PBT), Polyethylenterephthalat (PET), Polyamid (PA), Polycarbonat (PC), Cycloolefincopolymere (COC), Polyoximethylen (POM), Acrylnitril-butadien-styrol (ABS), Polyvinylchlorid (PVC) Ethylentetrafluorethylen (ETFE), Polytetrafluorethylen (PTFE), Polyvinylfluorid (PVF), Polyvinylidenfluorid (PVDF) und Ethylen-Tetrafluorethylen-Hexafluorpropylen-Fluorterpolymer (EFEP) und/oder Mischungen und/oder Co-Polymere dieser Materialien umfasst oder aus zumindest einem dieser Materialien hergestellt ist.In addition, it can be provided that it has a carrier layer made of plastic, in particular made of a translucent and/or thermoplastic material, with the carrier layer preferably containing at least one of the materials from the group polyimide (PI), polypropylene (PP), monoaxially oriented polypropylene ( MOPP), biaxially oriented polypropylene (BOPP), polyethylene (PE), polyphenylene sulfide (PPS), polyetheretherketone, (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). ), Polytetrafluoroethylene (PTFE), polyvinyl fluoride (PVF), polyvinylidene fluoride (PVDF) and ethylene-tetrafluoroethylene-hexafluoropropylene fluoroterpolymer (EFEP) and/or mixtures and/or copolymers of these materials or is made from at least one of these materials.
Es wäre hierbei auch denkbar, dass der erste Bereich auf einer Seite der Trägerschicht angeordnet ist und dass der zweite Bereich an der anderen Seite der Trägerschicht angeordnet ist. Dies kann insbesondere dann sinnvoll sein, wenn die Trägerschicht transparent und zumindest annähernd transparent ist. Für einen Betrachter wäre es hierbei nicht zwingend erkennbar, dass die beiden Bereiche nicht an derselben Seite der Trägerschicht ausgebildet sind. So kann für einen Betrachter beispielsweise der optische Eindruck entstehen, dass der erste Bereich den zweiten Bereich zumindest abschnittsweise umgibt, obwohl die Bereiche tatsächlich auf unterschiedlichen Seiten des Sicherheitselements appliziert sind.It would also be conceivable here for the first area to be arranged on one side of the carrier layer and for the second area to be arranged on the other side of the carrier layer. This can be useful in particular when the carrier layer is transparent and at least approximately transparent. In this case, it would not necessarily be recognizable to an observer that the two areas are not formed on the same side of the carrier layer. For example, an observer can get the visual impression that the first area surrounds the second area at least in sections, although the areas are actually applied to different sides of the security element.
Dabei kann es sein, dass das Sicherheitselement mit der Trägerschicht-Seite, also mit der einer Sichtseite des Sicherheitselements abgewandten Seite, auf einem Wert- oder Sicherheitspapier angebracht wird. Alternativ ist es natürlich auch denkbar, dass die Trägerschicht auf der Sichtseite, d.h. auf der Außenseite des Sicherheitselements ausgebildet ist. Hierbei kann es vorteilhaft sein, wenn die Trägerschicht lichtdurchlässig oder auch transparent ausgebildet ist. Zusätzlich wäre es gegebenenfalls auch vorteilhaft, wenn die Trägerschicht als Transferschicht ausgebildet ist, welche Transferschicht nach einer Applikation des Sicherheitselements auf einem Wertpapier vollständig und rückstandsfrei ablösbar ist.It can be the case that the security element is attached to a security paper with the carrier layer side, that is to say with the side facing away from a visible side of the security element. Alternatively, it is of course also conceivable that the carrier layer is formed on the visible side, i.e. on the outside of the security element. It can be advantageous here if the carrier layer is designed to be translucent or also transparent. In addition, it would also be advantageous if the carrier layer is designed as a transfer layer, which transfer layer can be detached completely and without leaving any residue after the security element has been applied to a security document.
Vorteilhaft ist auch eine Ausprägung, gemäß welcher vorgesehen sein kann, dass die Trägerschicht eine Dicke von 5 µm bis 1000 µm, besonders bevorzugt eine Dicke von 10 µm bis 50 µm, aufweist.Also advantageous is an embodiment according to which it can be provided that the carrier layer has a thickness of 5 μm to 1000 μm, particularly preferably a thickness of 10 μm to 50 μm.
Ferner kann es zweckmäßig sein, wenn mehrere der ersten Strukturen eine Gruppe bilden, deren Ausrichtungen derart aufeinander abgestimmt sind, dass sie in einem Beobachtungsraum einen Punkt der ersten Information abbilden, wobei sich die erste Information aus der Summe aller von der Gruppe dargestellten Punkte zusammensetzt und wobei durch Veränderung einer Einfallsrichtung des von der Lichtquelle erzeugten Lichtes und/oder bei Veränderung des Beobachtungswinkels eine Bewegung des Punktes in dem Beobachtungsraum erzeugt ist.Furthermore, it can be expedient if several of the first structures form a group whose orientations are matched to one another in such a way that they map a point of the first information item in an observation space, with the first information item resulting from the sum of all points represented by the group and wherein a movement of the point in the observation space is generated by changing an incidence direction of the light generated by the light source and/or by changing the observation angle.
Darüber hinaus kann vorgesehen sein, dass das Sicherheitselement mit zumindest einem dritten Bereich mit dritten Strukturen ausgebildet ist, welche dritten Strukturen durch eine Schicht mit farbkippenden Pigmenten, insbesondere Interferenzpigmenten, Pigmenten mit einem farbkippenden Dünnschichtaufbau oder Flüssigkristallpigmente, oder durch eine Schicht mit einem farbkippenden Dünnschichtaufbau gebildet sind, und/oder dass die dritten Strukturen durch zumindest eine Flüssigkristallschicht, insbesondere eine cholesterische Flüssigkristallschicht gebildet sind, und/oder dass die dritten Strukturen an einer einer Sichtseite abgewandten Seite mit zumindest einer einen Farbkippeffekt verstärkenden Schicht ausgebildet sind, und/oder dass die dritten Strukturen metallische Pigmente und/oder magnetische Pigmente und/oder Farbpigmente und/oder Farbstoffe enthalten, und welche dritten Strukturen eine dritte Information wiedergeben, wobei sich der erste Bereich und der dritte Bereich und/oder der zweite Bereich und der dritte Bereich zumindest abschnittsweise überlagern. So können beispielsweise über und auch neben den ersten und zweiten Strukturen weitere Beschichtungen bzw. Strukturen mit optischen Effekten verschiedenster Art vorliegen, welche zusätzliche optische Effekte aufweisen. Selbstverständlich sind auch entsprechende Kombination verschiedenster Beschichtungen bzw. Sicherheitsmerkmale möglich. So kann es auch von Vorteil sein, wenn sowohl die ersten Strukturen als auch die zweiten Strukturen zumindest bereichsweise von den dritten Strukturen bedeckt bzw. überdeckt sind. Zur weiteren Erhöhung der Fälschungssicherheit können derartige Beschichtungen auch lediglich partiell vorliegen. Vorteilhaft kann hierbei auch eine Ausbildung sein, gemäß welcher die dritten Strukturen als farbkippende Beschichtung ausgebildet sind und gemäß welcher zusätzlich weitere Strukturen mit einem reflektierenden Effekt, beispielsweise hervorgerufen durch eine metallische Beschichtung, ausgebildet sind. Diese dritten Strukturen und weiteren Strukturen können den ersten und/oder den zweiten Bereich zumindest partiell überlagern.In addition, it can be provided that the security element is formed with at least one third area with third structures, which third structures are formed by a layer with color-shifting pigments, in particular interference pigments, pigments with a color-shifting thin-layer structure or liquid crystal pigments, or by a layer with a color-shifting thin-layer structure and/or that the third structures are formed by at least one liquid crystal layer, in particular a cholesteric liquid crystal layer, and/or that the third structures are formed on a side facing away from a visible side with at least one layer that reinforces a color shift effect, and/or that the third Structures contain metallic pigments and / or magnetic pigments and / or color pigments and / or dyes, and which third structures reflect third information, wherein the first area and the third area and / or second area and the third area overlap at least in sections. Thus, for example, further coatings or structures with optical effects of various types can be present above and also next to the first and second structures, which have additional optical effects. Appropriate combinations of the most varied of coatings or security features are of course also possible. It can also be advantageous if both the first structures and the second structures are covered or covered at least in regions by the third structures. To further increase security against forgery, such coatings can also be present only partially. An embodiment can also be advantageous here, according to which the third structures are formed as a color-shifting coating and according to which additional structures with a reflective effect, for example caused by a metallic coating, are formed. These third structures and further structures can at least partially overlay the first and/or the second area.
Wenn die dritten Strukturen metallische Pigmente und/oder magnetische Pigmente und/oder Farbpigmente und/oder Farbstoffe enthalten, und damit keinen farbkippenden Effekt erzeugen, kann eine Anordnung zweckmäßig sein, gemäß welcher die dritten Strukturen auf einer nachfolgend beschriebenen, reflektierenden Schicht mit einem hohen Brechungsindex angeordnet sind. So kann beispielsweise eine Farblackschicht auf einer sogenannten HRI-Schicht angeordnet sein.If the third structures contain metallic pigments and/or magnetic pigments and/or color pigments and/or dyes, and thus produce no color-shifting effect, an arrangement may be appropriate according to which the third structures on a reflective layer described below with a high refractive index are arranged. For example, a colored lacquer layer can be arranged on a so-called HRI layer.
Insbesondere wenn die dritten Strukturen mit einer Schicht mit farbkippenden Pigmenten oder die mit einem farbkippenden Dünnschichtaufbau ausgebildet sind, kann es sein, dass diese zumindest eine Absorberschicht und zumindest eine Distanzschicht umfassen.In particular, if the third structures are formed with a layer with color-shifting pigments or with a color-shifting thin-layer structure, it may be the case that they comprise at least one absorber layer and at least one spacer layer.
Die Ausbildung eines dritten Bereichs mit dritten Strukturen kann auf vorteilhafte Art und Weise zu einer zusätzlichen Erhöhung der Gestaltungsmöglichkeiten und damit der Fälschungssicherheit beitragen. Beispielsweise kann der farbkippende Dünnschichtaufbau oder können die farbkippenden Pigmente zumindest eine Absorberschicht und zumindest eine Distanzschicht aus einem dielektrischen Material aufweisen. Zudem ist es denkbar, dass der Dünnschichtaufbau zumindest eine Reflexionsschicht aufweist, wobei die Distanzschicht zwischen Reflexionsschicht und Absorberschicht angeordnet sein kann.The formation of a third area with third structures can contribute in an advantageous manner to an additional increase in design options and thus counterfeit security. For example, the color-shifting thin-layer structure or the color-shifting pigments can have at least one absorber layer and at least one spacer layer made of a dielectric material. In addition, it is conceivable for the thin-layer structure to have at least one reflection layer, with the spacer layer being able to be arranged between the reflection layer and the absorber layer.
Absorberschicht, Distanzschicht bzw. Reflexionsschicht können dabei auf den ersten und/oder zweiten Strukturen aufgebracht sein, insbesondere aufgedruckt und/oder aufgedampft sein. Je nachdem, welche Seite des Sicherheitselements als Sichtseite betrachtet wird, sind verschiedene Schicht-Reihenfolgen denkbar bzw. zweckmäßig. So kann beispielsweise ein Aufbau mit einer Reihenfolge "Trägerschicht oder Schicht mit darin eingebrachter erster und/oder zweiter Struktur - Reflexionsschicht - Distanzschicht - Absorberschicht" vorgesehen sein. Alternativ ist auch ein Aufbau mit einer Reihenfolge "Trägerschicht oder Schicht mit darin eingebrachter erster und/oder zweiter Struktur - Absorberschicht - Distanzschicht- Reflexionsschicht" denkbar. Die Sichtseite ist hierbei stets jene Seite, von welcher aus ein Betrachter von Absorberschicht in Richtung Reflexionsschicht blickt.The absorber layer, spacer layer or reflection layer can be applied to the first and/or second structures, in particular printed and/or vapor-deposited. Depending on which side of the security element is considered to be the visible side, different layer sequences are conceivable or expedient. For example, a structure with a sequence “carrier layer or layer with a first and/or second structure introduced therein—reflection layer—spacer layer—absorber layer” can be provided. Alternatively, a structure with a sequence “carrier layer or layer with first and/or second structure introduced therein—absorber layer—spacer layer—reflection layer” is also conceivable. In this case, the visible side is always that side from which an observer looks from the absorber layer in the direction of the reflection layer.
An dieser Stelle sei darauf hingewiesen, dass die Formulierung "eine Schicht ist auf etwas aufgebracht" so zu verstehen ist, dass die Schicht direkt aufgebracht sein kann, oder dass sich zwischen der aufgebrachten Schicht und dem, worauf die Schicht aufgebracht ist, noch eine oder mehrere Zwischenschichten befinden können. An dieser Stelle sei auch darauf hingewiesen, dass zwischen den in diesem Dokument beschriebenen Schichten eine oder auch mehrere Zwischenschichten angeordnet sein können. Es ist somit nicht zwingend erforderlich, dass die beschriebenen Schichten einander kontaktieren. Weiters sei darauf hingewiesen, dass der Begriff Schicht in diesem Dokument so zu verstehen ist, dass eine Schicht auch aus mehreren Teilschichten aufgebaut sein kann.At this point it should be noted that the phrase "a layer is applied to something" is to be understood in such a way that the layer can be applied directly, or that there is another or there may be several intermediate layers. At this point it should also be pointed out that one or more intermediate layers can be arranged between the layers described in this document. It is therefore not absolutely necessary that the described layers contact each other. It should also be pointed out that the term layer in this document is to be understood in such a way that a layer can also be made up of a number of sub-layers.

Dem Fachmann sind grundsätzlich Methoden zur Ausbildung, respektive zur Einbringung von achromatischen Strukturen bekannt. Beispielsweise kann dies mittels Laser und insbesondere mittels Laserablation erfolgen. Dabei können die ersten Strukturen, respektive die Mikrospiegel, welche auf einem Master bzw. einem Abformelement aufgebracht sein können, mittels Laserablation quasi mit den zweiten, achromatischen Strukturen, über- oder beschrieben werden.Also advantageous is an embodiment according to which it can be provided that the second structures are introduced at least in sections into the first structures, in particular are embossed or engraved into the first structures.

- Bereitstellen zumindest eines Abformelements oder zumindest einer Abformvorrichtung umfassend erste Strukturen und zweite Strukturen,
- wobei die ersten Strukturen eine erste Information in unterschiedliche Raumbereiche reflektieren, sodass für einen Betrachter bei entsprechender Bewegung einer Lichtquelle und/oder bei Veränderung eines Beobachtungswinkels ein Bewegungsbild entsteht, wobei bei Bewegung der Lichtquelle und/oder Veränderung des Beobachtungswinkels gleichzeitig eine Bewegung der ersten Information entsteht,

- Molding the first structures and the second structures in the carrier layer or in the layer.
Durch die erfindungsgemäße Lösung wird durch Kombination zweier Technologien bzw. zweier verschiedenartiger Sicherheitsmerkmale die Fälschungssicherheit von Sicherheitselementen für Wertpapiere oder Sicherheitspapiere wesentlich erhöht. Die Verbindung von Bewegungseffekten mit statischen und/oder blickwinkelunabhängigen Merkmalen ermöglicht ein hohes Maß an Individualisierbarkeit, respektive eine große Vielfalt an Gestaltungsmöglichkeiten. Damit einher geht eine signifikante Erhöhung der Fälschungssicherheit.With the solution according to the invention, the counterfeit protection of security elements for securities or security papers is significantly increased by combining two technologies or two different types of security features. The combination of movement effects with static and/or viewing angle-independent features enables a high degree of customization and a large variety of design options. This is accompanied by a significant increase in protection against counterfeiting.
Dabei kann auf einer Abformvorrichtung bzw. einer Prägewalze ein Abformelement angeordnet sein, auf welchem Abformelement die ersten und/oder die zweiten Strukturen ausgebildet sein können. Gattungsgemäße Abformelemente sind dem Fachmann grundsätzlich bekannt. Bei einem Abformelement kann es sich beispielsweise um ein Metallblech oder um eine Polymer-Platte handeln, welche bevorzugt eine Spiegelreflexionsfläche aufweisen. Zur Herstellung eines solchen Abformelements oder Masters werden Metalle wie Nickel, Stahl, Messing oder Polymere wie PMMA, PC, PS, ausgehärtete UV-Lacke oder ähnliche verwendet.In this case, a molding element can be arranged on a molding device or an embossing roller, on which molding element the first and/or the second structures can be formed. Generic impression elements are known in principle to the person skilled in the art. A molding element can be, for example, a metal sheet or a polymer plate, which preferably have a mirror reflection surface. Metals such as nickel, steel, brass or polymers such as PMMA, PC, PS, cured UV lacquers or the like are used to produce such an impression element or master.
Das Einbringen von statischen und/oder blickwinkelunabhängigen Strukturen kann beispielsweise mittels Laser und insbesondere mittels Laserablation erfolgen. Dabei können die ersten Strukturen, beispielsweise die Mikrospiegel, welche auf einem Master bzw. einem Abformelement aufgebracht sein können, mittels Laserablation quasi mit den zweiten, statischen und/oder blickwinkelunabhängigen Strukturen, über- oder beschrieben werden. Durch die Einbringung der zweiten, statischen und/oder blickwinkelunabhängigen Strukturen mittels Laser können die Positionen bzw. die Anordnung der Strukturen am Master zueinander immer gleichbleiben. Die damit erzielbare Genauigkeit bzw. Präzision kann zu einer zusätzlichen Erhöhung der Fälschungssicherheit weiter beitragen.Static structures and/or structures that are independent of the viewing angle can be introduced, for example, by means of a laser and in particular by means of laser ablation. In this case, the first structures, for example the micromirrors, which can be applied to a master or a molding element, can be written over or written by means of laser ablation, so to speak, with the second, static and/or viewing angle-independent structures. By introducing the second, static and/or viewing angle-independent structures by means of a laser, the positions or the arrangement of the structures on the master can always remain the same in relation to one another. The accuracy or precision that can be achieved in this way can further contribute to an additional increase in security against forgery.

So kann eine Anordnung auf einer Abformvorrichtung 12 , wie einer Prägewalze 13 oder einem Shim und in weiterer Folge ein Aufprägen in eine insbesondere UV-härtbare Schicht 14 bzw. Prägelackschicht erfolgen.In one possible variant of the manufacturing method, it can be expedient if an
In einer weiteren Variante des Herstellungsverfahrens kann es auch sein, dass ein Abformelement 17 bzw. Master mit ersten Strukturen 3 bereitgestellt wird und wenn in oder auch neben diesen ersten Strukturen 3 die zweiten Strukturen 5, beispielsweise mittels Laserablation, eingebracht werden. Ein derart hergestellter Master kann auch in einem oder mehreren Folgeschritten vervielfältigt werden, wobei der Fachwelt die Ausführung derartiger Kopierschritte vom Positiven ins Negative und vice versa grundsätzlich geläufig ist. In weiterer Folge kann eine Anordnung auf einer Abformvorrichtung 12 wie einer Prägewalze 13 oder einem Shim und ein Aufprägen der ersten und zweiten Strukturen 3, 5 in eine insbesondere UV-härtbare Schicht 14 bzw. Prägelackschicht erfolgen.In a further variant of the production method, it can also be the case that an
Es kann gegebenenfalls auch zweckmäßig sein, wenn eine fertige Abformvorrichtung 12 bzw. Prägewalze 13 oder ein fertiger Shim erst nachträglich zur Einbringung der zweiten Strukturen 5 mittels Laser beschrieben wird. So kann eine zusätzliche vorteilhafte Individualisierbarkeit gegeben sein.It may also be expedient if a finished molding device 12 or embossing roller 13 or a finished shim is not written on until after the introduction of the
Im Zuge weiterer Verfahrensschritte können diverse weiterverarbeitende Schritte an dem Sicherheitselement 1 vorgesehen sein. Beispielsweise können weitere Schichten aufgebracht werden, so wie dies durch die
