Definitions
- the invention relates to a security element for securities or security papers, the security element having a first side and a second side opposite the first side and at least one color-shifting first area that is perceptible when viewed from the first side.
- Security elements of this type are usually used to increase the security against forgery of securities or security papers, such as bank notes, ID cards, credit cards, ATM cards, tickets, etc.
- the object of the present invention is to create a security element with increased security against forgery, which is easy to manufacture and easy to verify.
- this object is achieved by a security element of the type mentioned at the outset in that the security element has at least one second area that produces a viewing angle independent of a viewing angle when viewed from the first side, a color shift effect being created when a viewing angle is changed in the first area, the The first area under at least a first viewing angle generates the same color impression as the second area and wherein the first area has a different color impression than the second area under at least a second viewing angle different from the first viewing angle.
- the solution according to the invention significantly increases the security against forgery of securities and security papers.
- This is implemented in particular in that the first and the second area produce the same color impression for a viewer and the first area and the second area only differ in color from one another by tilting the security element by a viewing angle.
- the security element according to the invention is simple to produce in comparison to more complex security features and, moreover, can be easily verified with regard to its authenticity even for an inexperienced observer or user.
- the term area means a visual impression that is created for a viewer.
- the areas described are surface sections that a viewer can perceive.
- an area cannot only be recognizable or visible from one side of the security feature. This can be achieved in that, for example, a constant-color printing ink can be seen in the area, which is applied to one side of a transparent carrier layer and is also recognizable in the same way or in sections on the second side of the transparent carrier layer.
- An area which was applied to a first side of the security element due to the manufacturing process can thus optionally also be visible at least in sections on a second side of this security element.
- the term area therefore does not mean a special structure or concrete layer structure as such, but rather the optical effect that can be perceived in the section.
- the security element viewed from the first side, can have at least one first color-shifting effect and at least one first color impression that is independent of a viewing angle and matched to the color-shifting effect
- the security element viewed from the second side, having at least one second color-shifting effect and at least one second of can have a color impression that is independent of a viewing angle and is matched to the second color-shifting effect.

- first area and the second area form a continuously closed area with the same color impression at the at least one viewing angle at which the first area and the second area have the same color impression.
- the depicted motif is therefore not visually recognizable to a viewer.
- the third area and the second area form a continuously closed area with the same color impression at the at least one viewing angle at which the third area and the second area have the same color impression and / or that the first area and the fourth area at the at least one viewing angle at which the first area and the fourth area have the same color impression form a continuously closed area with the same color impression.
- This also has the effect that the third and the second area or the first and the fourth area do not differ from one another for a viewer or do not stand out from one another, which can also have a positive effect on the security element's security against counterfeiting.
- first area and the third area are arranged opposite one another at least in sections and / or that the second area and the fourth area are arranged opposite one another at least in sections.

It may be necessary that the second area 4 of constant color is applied with the aid of a laminating adhesive 17, by means of which a sufficient adhesive effect can be achieved between the two carrier layers 15 or between the printing ink of the second area 4 with constant color and the carrier layers 15.
- a color-changing first area 3 can be applied in sections and a color-changing third area 8 can be applied in sections on the second side 7 of the security element 1.
- the two color-shifting areas 3, 8 can expediently be thin-layer structures 11, which - viewed from the carrier layers 15 - can be formed by an opaque reflective layer 14, a spacer layer 13 and an absorber layer 12. Since the reflective layer 14 is preferably an opaque layer, the respective underlying structure cannot be seen by a viewer. Thus, a viewer sees the color-changing first area 3 on the first side 2, as well as the second area 4, which is constant in color, in the recesses 18 formed as a result of the application in sections through the transparent carrier layer 15 he recognizes the color-shifting third area 8, as well as the color-constant second area 4 in the recesses 18 formed as a result of the application in sections through the transparent carrier layer 15.
- the carrier layer 15 can have a thickness 16 of 5 ⁇ m to 1000 ⁇ m, particularly preferably a thickness 16 of 8 ⁇ m to 50 ⁇ m.
- the carrier layer 15 can advantageously be made thicker than the areas 3, 4, 8, 9 arranged on the sides 2, 7.
- the first area 3 and the third area 8 can be arranged opposite one another at least in sections.
- the second area 4 and the fourth area 9 can be arranged opposite one another at least in sections or reproduce a pattern.

Description
Die Erfindung betrifft ein Sicherheitselement für Wertpapiere oder Sicherheitspapiere, wobei das Sicherheitselement eine erste Seite und eine der ersten Seite gegenüberliegende zweite Seite und zumindest einen bei Betrachtung von der ersten Seite her wahrnehmbaren farbkippenden ersten Bereich aufweist.The invention relates to a security element for securities or security papers, the security element having a first side and a second side opposite the first side and at least one color-shifting first area that is perceptible when viewed from the first side.
Sicherheitselemente dieser Art werden üblicherweise verwendet um die Fälschungssicherheit von Wertpapieren oder Sicherheitspapieren, wie Banknoten, Ausweisen, Kreditkarten, Bankomatkarten, Tickets etc. zu erhöhen.Security elements of this type are usually used to increase the security against forgery of securities or security papers, such as bank notes, ID cards, credit cards, ATM cards, tickets, etc.
Aufgabe der vorliegenden Erfindung ist es, ein Sicherheitselement mit erhöhter Fälschungssicherheit zu schaffen, welches einfach herstellbar und leicht zu verifizieren ist.The object of the present invention is to create a security element with increased security against forgery, which is easy to manufacture and easy to verify.
Diese Aufgabe wird durch ein Sicherheitselement der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass das Sicherheitselement zumindest einen bei Betrachtung von der ersten Seite einen Betrachtungswinkel unabhängigen Farbeindruck erzeugenden, zweiten Bereich aufweist, wobei bei Veränderung eines Betrachtungswinkels in dem ersten Bereich ein Farbkippeffekt entsteht, wobei der erste Bereich unter zumindest einem ersten Betrachtungswinkel denselben Farbeindruck erzeugt, wie der zweite Bereich und wobei der erste Bereich unter zumindest einem zweiten, von dem ersten Betrachtungswinkel unterschiedlichen, Betrachtungswinkel einen anderen Farbeindruck aufweist, als der zweite Bereich.According to the invention, this object is achieved by a security element of the type mentioned at the outset in that the security element has at least one second area that produces a viewing angle independent of a viewing angle when viewed from the first side, a color shift effect being created when a viewing angle is changed in the first area, the The first area under at least a first viewing angle generates the same color impression as the second area and wherein the first area has a different color impression than the second area under at least a second viewing angle different from the first viewing angle.
Durch die erfindungsgemäße Lösung wird die Fälschungssicherheit von Wertpapieren und Sicherheitspapieren wesentlich erhöht. Dies wird insbesondere dadurch realisiert, dass der erste und der zweite Bereich für einen Betrachter denselben Farbeindruck erzeugen und sich erst durch Verkippen des Sicherheitselements um einen Betrachtungswinkel der erste Bereich und der zweite Bereich farblich voneinander unterscheiden. Vorteilhafterweise ist das erfindungsgemäße Sicherheitselement im Vergleich zu aufwendigeren Sicherheitsmerkmalen einfach herstellbar und zudem auch für einen wenig geübten Betrachter, respektive Benutzer leicht im Hinblick auf seine Echtheit zu verifizieren.The solution according to the invention significantly increases the security against forgery of securities and security papers. This is implemented in particular in that the first and the second area produce the same color impression for a viewer and the first area and the second area only differ in color from one another by tilting the security element by a viewing angle. Advantageously, the security element according to the invention is simple to produce in comparison to more complex security features and, moreover, can be easily verified with regard to its authenticity even for an inexperienced observer or user.
Es sei an dieser Stelle explizit darauf hingewiesen, dass im Kontext der Erfindung mit dem Begriff Bereich ein für einen Betrachter entstehender, optischer Eindruck gemeint ist. Somit handelt es sich bei den beschriebenen Bereichen um Oberflächenabschnitte, welcher ein Betrachter wahrnehmen kann. Beispielsweise kann ein Bereich nicht nur von einer Seite des Sicherheitsmerkmals erkennbar bzw. sichtbar sein. Dies kann dadurch realisiert sein, dass beispielsweise in dem Bereich eine farbkonstante Druckfarbe erkennbar ist, welche auf einer Seite einer transparenten Trägerschicht aufgebracht ist und gleichermaßen oder abschnittsweise auf der zweiten Seite der transparenten Trägerschicht ebenfalls erkennbar ist. Ein Bereich, welcher fertigungsbedingt auf einer ersten Seite des Sicherheitselements aufgebracht wurde kann somit gegebenenfalls auch auf einer zweiten Seite dieses Sicherheitselements zumindest abschnittsweise sichtbar sein. Unter dem Begriff Bereich ist somit kein spezieller Aufbau oder konkreter Schichtaufbau als solcher gemeint, sondern der im Abschnitt wahrnehmbare, optische Effekt.It should be explicitly pointed out at this point that, in the context of the invention, the term area means a visual impression that is created for a viewer. Therewith the areas described are surface sections that a viewer can perceive. For example, an area cannot only be recognizable or visible from one side of the security feature. This can be achieved in that, for example, a constant-color printing ink can be seen in the area, which is applied to one side of a transparent carrier layer and is also recognizable in the same way or in sections on the second side of the transparent carrier layer. An area which was applied to a first side of the security element due to the manufacturing process can thus optionally also be visible at least in sections on a second side of this security element. The term area therefore does not mean a special structure or concrete layer structure as such, but rather the optical effect that can be perceived in the section.
Das Sicherheitselement kann von der ersten Seite her betrachtet zumindest einen ersten farbkippenden Effekt und zumindest einen ersten von einem Betrachtungswinkel unabhängigen, auf den farbkippenden Effekt abgestimmten Farbeindruck aufweisen, wobei das Sicherheitselement von der zweiten Seite her betrachtet zumindest einen zweiten farbkippenden Effekt und zumindest einen zweiten von einem Betrachtungswinkel unabhängigen, auf den zweiten farbkippenden Effekt abgestimmten Farbeindruck aufweisen kann. Unter "abgestimmt" wird in dem vorliegenden Zusammenhang verstanden, dass unter einem bestimmten Betrachtungswinkel aufeinander abgestimmten Farbeindrücke für einen Betrachter identisch erscheinen.The security element, viewed from the first side, can have at least one first color-shifting effect and at least one first color impression that is independent of a viewing angle and matched to the color-shifting effect, the security element, viewed from the second side, having at least one second color-shifting effect and at least one second of can have a color impression that is independent of a viewing angle and is matched to the second color-shifting effect. In the present context, “matched” is understood to mean that color impressions matched to one another appear identical to a viewer from a specific viewing angle.
Gemäß einer vorteilhaften Weiterbildung kann es zweckmäßig sein, dass ein Zusammenspiel von erstem farbkippenden Effekt und erstem Betrachtungswinkel unabhängigem Farbeindruck von der zweiten Seite nicht wahrnehmbar ist, und ein Zusammenspiel von zweitem farbkippenden Effekt und zweitem Betrachtungswinkel unabhängigem Farbeindruck von der ersten Seite aus nicht wahrnehmbar ist.According to an advantageous development, it can be useful that an interaction of the first color-changing effect and the first color impression independent of the viewing angle is not perceptible from the second side, and an interaction of the second color-changing effect and the second color impression independent of the viewing angle cannot be perceived from the first side.
Gemäß einer vorteilhaften Weiterbildung kann vorgesehen sein, dass der zumindest eine farbkippende erste Bereich und/oder der zumindest zweite Bereich mit einem, von einem Betrachtungswinkel unabhängigen, Farbeindruck zumindest abschnittsweise auf der zweitenSeite erkennbar sind. Somit können vorteilhafterweise der farbkippende bzw. der farbkonstante Effekt auf einfache Art und Weise auf beiden Seiten des Sicherheitselementes realisiert werden.According to an advantageous development it can be provided that the at least one color-changing first area and / or the at least second area can be recognized at least in sections on the second side with a color impression independent of a viewing angle. In this way, the color-shifting effect or the color-constant effect can advantageously be implemented in a simple manner on both sides of the security element.
Es kann ein beidseitig wahrnehmbares, farbkippendes Feature mittels lediglich einer farbkippenden Schicht gefertigt werden, was sich sowohl im Hinblick auf eine Fälschungssicherheit, als auch in wirtschaftlicher Sicht als äußert zweckmäßig erweisen kann.A color-shifting feature that is perceptible on both sides can be produced by means of just one color-shifting layer, which can prove to be extremely expedient both in terms of forgery protection and from an economic point of view.
Des Weiteren kann es zweckmäßig sein, wenn das Sicherheitselement auf der zweiten Seite einen farbkippenden dritten Bereich aufweist, wobei der dritte Bereich unter zumindest einem ersten Betrachtungswinkel denselben Farbeindruck erzeugt, wie der zweite Bereich und wobei der dritte Bereich unter zumindest einem zweiten, von dem ersten Betrachtungswinkel unterschiedlichen Betrachtungswinkel einen anderen Farbeindruck aufweist, als der zweite Bereich und/oder dass das Sicherheitselement auf einer zweiten Seite einen vierten Bereich mit einem von einem Betrachtungswinkel unabhängigen Farbeindruck aufweist, wobei der erste Bereich unter zumindest einem ersten Betrachtungswinkel denselben Farbeindruck erzeugt, wie der vierte Bereich und wobei der erste Bereich unter zumindest einem zweiten von dem ersten Betrachtungswinkel unterschiedlichen Betrachtungswinkel einen anderen Farbeindruck aufweist, als der vierte Bereich.Furthermore, it can be expedient if the security element has a color-changing third area on the second side, the third area producing the same color impression as the second area under at least a first viewing angle and the third area under at least a second of the first Viewing angle different viewing angle has a different color impression than the second area and / or that the security element has a fourth area on a second side with a color impression independent of a viewing angle, the first area generating the same color impression as the fourth under at least one first viewing angle Area and wherein the first area has a different color impression than the fourth area under at least one second viewing angle different from the first viewing angle.
Diese Weiterbildung kann insbesondere deshalb vorteilhaft sein, weil eine doppelseitige Anbringung von farbkippenden und von Betrachtungswinkel-unabhängigen Bereichen eine große Vielfalt an Gestaltungsmöglichkeiten bietet und somit auch eine hohe Fälschungssicherheit erlaubt. Für eine hohe Fälschungssicherheit kann es zudem besonders vorteilhaft sein, wenn Sicherheitsmerkmale an beiden Seiten eines Wertpapiers oder Sicherheitspapieres anbringbar sind.This further development can be advantageous in particular because a double-sided attachment of color-tilting areas that are independent of the viewing angle offers a great variety of design options and thus also allows a high level of protection against forgery. For a high level of protection against forgery, it can also be particularly advantageous if security features can be attached to both sides of a security paper or security paper.
Ferner kann vorgesehen sein, dass der erste Bereich und der zweite Bereich unter dem zumindest einen Betrachtungswinkel, unter dem der erste Bereich und der zweite Bereich den gleichen Farbeindruck aufweisen, eine durchgehend geschlossene Fläche mit demselben Farbeindruck bilden. Für einen Betrachter ist das dargestellte Motiv somit optisch nicht erkenntlich.Furthermore, it can be provided that the first area and the second area form a continuously closed area with the same color impression at the at least one viewing angle at which the first area and the second area have the same color impression. The depicted motif is therefore not visually recognizable to a viewer.
Dies hat den positiven Effekt, dass sich der erste und der zweite Bereich für einen Betrachter optisch nicht voneinander unterscheiden, respektive sich nicht voneinander abheben. Dies kann zusätzlich zu einer Erhöhung der Fälschungssicherheit des Sicherheitselementes beitragen. In der Regel sind auch ungeschulte Betrachter in der Lage zu erkennen, ob der Farbeindruck der Bereiche einer Seite unter einem bestimmen Betrachtungswinkel ident ist, oder ob sich die Bereiche voneinander unterscheiden. Wenn die farbkippenden und die Betrachtungswinkel-unabhängigen Bereiche direkt aneinander angrenzend ausgebildet sind, kann grundsätzlich auch ein Laie erkennen, ob eine Gleichheit vorliegt, oder nicht.This has the positive effect that the first and the second area do not visually differ from one another for a viewer, or do not stand out from one another. This can also contribute to increasing the security element's security against forgery. As a rule, even untrained viewers are able to recognize whether the color impression of the areas of a page is identical under a certain viewing angle, or whether the areas differ from each other. If the color-changing and viewing-angle-independent areas are formed directly adjacent to one another, even a layperson can in principle recognize whether or not they are identical.
Darüber hinaus kann vorgesehen sein, dass der dritte Bereich und der zweite Bereich unter dem zumindest einen Betrachtungswinkel, unter dem der dritte Bereich und der zweite Bereich den gleichen Farbeindruck aufweisen, eine durchgehend geschlossene Fläche mit demselben Farbeindruck bilden und/oder dass der erste Bereich und der vierte Bereich unter dem zumindest einen Betrachtungswinkel, unter dem der erste Bereich und der vierte Bereich den gleichen Farbeindruck aufweisen, eine durchgehend geschlossene Fläche mit demselben Farbeindruck bilden.In addition, it can be provided that the third area and the second area form a continuously closed area with the same color impression at the at least one viewing angle at which the third area and the second area have the same color impression and / or that the first area and the fourth area at the at least one viewing angle at which the first area and the fourth area have the same color impression form a continuously closed area with the same color impression.
Dies hat ebenso den Effekt, dass sich der dritte und der zweite Bereich bzw. der erste und der vierte Bereich für einen Betrachter nicht voneinander unterscheiden, respektive sich nicht voneinander abheben, was sich zusätzlich positiv auf die Fälschungssicherheit des Sicherheitselementes auswirken kann.This also has the effect that the third and the second area or the first and the fourth area do not differ from one another for a viewer or do not stand out from one another, which can also have a positive effect on the security element's security against counterfeiting.
Vorteilhaft ist auch eine Ausprägung, gemäß welcher vorgesehen sein kann, dass der erste Bereich und der dritte Bereich zumindest abschnittsweise einander gegenüberliegend angeordnet sind und/oder dass der zweite Bereich und der vierte Bereich zumindest abschnittsweise einander gegenüberliegend angeordnet sind.An embodiment is also advantageous, according to which it can be provided that the first area and the third area are arranged opposite one another at least in sections and / or that the second area and the fourth area are arranged opposite one another at least in sections.
So ist es möglich, zwei Sicherheitsmerkmale auf einem einzigen Sicherheitselement zu realisieren, wodurch dieses Sicherheitselement verhältnismäßig klein ausführbar ist. Wenn der erste Bereich und der dritte Bereich auf eine bestimmte, durch die Fertigung des Sicherheitselementes definierte Art und Weise gegenüberliegend angeordnet sind, kann sich dies vorteilhaft auf die Fälschungssicherheit auswirken. Wie oder inwieweit der erste und der dritte Bereich einander gegenüberliegend angeordnet sind, kann im Zuge der Registerabstimmung definiert werden. Beispielsweise können der erste und der dritte Bereich in Form und Größe übereinstimmen und deckungsgleich übereinander angeordnet sein. Alternativ kann es auch sinnvoll sein, wenn der erste und der dritte Bereich einander gegenüberliegend und mit einem definierten Versatz zueinander angeordnet sind.It is thus possible to implement two security features on a single security element, as a result of which this security element can be made relatively small. If the first area and the third area are arranged opposite one another in a certain manner defined by the manufacture of the security element, this can have an advantageous effect on the security against forgery. How or to what extent the first and third areas are arranged opposite one another can be defined in the course of register coordination. For example, the first and third areas can match in shape and size and be arranged congruently one above the other. Alternatively, it can also be useful if the first and third areas are arranged opposite one another and with a defined offset from one another.
Gemäß einer Weiterbildung ist es möglich, dass der erste Bereich und der dritte Bereich farblich ident sind und/oder dass der zweite Bereich und der vierte Bereich farblich ident sind.According to a development, it is possible for the first area and the third area to be identical in color and / or for the second area and the fourth area to be identical in color.
Diese Weiterbildung kann auf positive Art und Weise zu einer kostengünstigen Ausbildung des Sicherheitselementes beitragen. Zudem können dadurch optisch ansprechende Designs kreiert werden.This further development can contribute in a positive way to a cost-effective design of the security element. In addition, visually appealing designs can be created.
Ferner kann es zweckmäßig sein, wenn der erste Bereich und/oder der dritte Bereich und/oder der zweite Bereich und/oder der vierte Bereich als Buchstabe, Zahl, Zeichen, Symbol oder Teil eines Bildes oder Muster ausgebildet ist.It can also be useful if the first area and / or the third area and / or the second area and / or the fourth area is designed as a letter, number, character, symbol or part of an image or pattern.
Darüber hinaus kann vorgesehen sein, dass Buchstabe, Zahl, Zeichen, Symbol oder Teil eines Bildes oder Musters auf der ersten Seite und auf der zweiten Seite verschieden ausgebildet sind.In addition, it can be provided that letters, numbers, characters, symbols or parts of an image or pattern are designed differently on the first side and on the second side.
Die Ausbildung von Buchstaben, Zahlen, Zeichen, Symbolen oder Teilen eines Bildes oder Musters, insbesondere von verschiedenartig geformten und unterschiedlich großen Konturen kann auf einfache Art und Weise eine hohe Fälschungssicherheit bieten. Insbesondere bei komplexen, respektive bei aufwendigen Konturen und Formen kann eine Nacharmbarkeit stark erschwert sein.The formation of letters, numbers, characters, symbols or parts of an image or pattern, in particular of differently shaped and differently sized contours, can offer a high level of protection against forgery in a simple manner. In particular with complex or elaborate contours and shapes, it can be very difficult to reconnect.
Gemäß einer besonderen Ausprägung ist es möglich, dass zumindest auf der ersten Seite ein farbkippender fünfter Bereich ausgebildet ist, welcher vor Veränderung des Betrachtungswinkels denselben Farbeindruck erzeugt, wie der zweite Bereich und welcher nach Veränderung des Betrachtungswinkels denselben Farbeindruck erzeugt, wie der erste Bereich vor Veränderung des Betrachtungswinkels.According to a particular embodiment, it is possible that at least on the first side a color-changing fifth area is formed which, before changing the viewing angle, generates the same color impression as the second area and which, after changing the viewing angle, generates the same color impression as the first area before the change the viewing angle.
Diese Ausprägung ermöglicht eine Vielzahl an Design- und Gestaltungsmöglichkeiten, sodass sowohl hoch fälschungssichere als auch optisch ansprechende Sicherheitselemente kreierbar sind. Selbstverständlich wäre es auch denkbar und gegebenenfalls zweckmäßig, wenn anstelle oder zusätzlich zu dem farbkippenden fünften Bereich ein weiterer farbkonstanter, respektive ein weiterer Betrachtungswinkel-unabhängiger Bereich ausgebildet ist. Ein solcher weiterer Bereich könnte vorteilhafterweise durch ein Echtfarbenbild oder auch durch schwarze oder silberne Farben gebildet sein.This form enables a multitude of design and configuration options, so that both highly counterfeit-proof and visually appealing security elements can be created. Of course, it would also be conceivable and, if necessary, expedient if, instead of or in addition to the color-shifting fifth area, a further area that is constant in color or a further area that is independent of the viewing angle is formed. Such a further area could advantageously be formed by a true color image or also by black or silver colors.
Entsprechend einer vorteilhaften Weiterbildung kann vorgesehen sein, dass der erste Bereich und/oder der dritte Bereich eine Schicht mit farbkippenden Pigmenten, insbesondere Interferenzpigmenten, Pigmenten mit einem farbkippenden Dünnschichtaufbau oder Flüssigkristallpigmenten, oder eine Schicht mit einem farbkippenden Dünnschichtaufbau aufweist.According to an advantageous development, it can be provided that the first area and / or the third area has a layer with color-shifting pigments, in particular interference pigments, pigments with a color-shifting thin-layer structure or liquid crystal pigments, or a layer with a color-shifting thin-layer structure.
Insbesondere kann es vorteilhaft sein, wenn der erste Bereich und/oder der dritte Bereich zumindest eine Flüssigkristallschicht, insbesondere zumindest eine cholesterische Flüssigkristallschicht aufweist.In particular, it can be advantageous if the first area and / or the third area has at least one liquid crystal layer, in particular at least one cholesteric liquid crystal layer.
Ferner kann vorgesehen sein, dass der erste Bereich und/oder der dritte Bereich zumindest eine den Farbkippeffekt verstärkende Schicht aufweist, insbesondere eine Schicht aus dunkler Farbe und/oder eine Schicht aus Metalloxiden wie beispielsweise unterstöchiometrischem Aluminiumoxid.Furthermore, it can be provided that the first area and / or the third area has at least one layer that enhances the color shift effect, in particular a layer of dark color and / or a layer of metal oxides such as, for example, substoichiometric aluminum oxide.
So kann die den Farbkippeffekt verstärkende Schicht beispielsweise auf der Flüssigkristallschicht oder der Schicht aus farbkippenden Pigmenten aufgebracht sein, sodass die Schicht aus farbkippenden Pigmenten oder die Flüssigkristallschicht zwischen der den Farbkippeffekt verstärkenden Schicht und einer Trägerschicht angeordnet ist. Die den Farbkippeffekt verstärkende Schicht kann aber auch zwischen der Trägerschicht und der Schicht aus farbkippenden Pigmenten oder der zumindest einen Flüssigkristallschicht angeordnet sein. Zudem ist es auch möglich, dass die Trägerschicht zwischen der den Farbkippeffekt verstärkenden Schicht und der Schicht aus farbkippenden Pigmenten oder der Flüssigkristallschicht und angeordnet ist.For example, the layer that enhances the color-shifting effect can be applied to the liquid crystal layer or the layer of color-shifting pigments, so that the layer of color-shifting pigments or the liquid crystal layer is arranged between the layer that enhances the color-shifting effect and a carrier layer. The layer that enhances the color-shifting effect can, however, also be arranged between the carrier layer and the layer of color-shifting pigments or the at least one liquid crystal layer. In addition, it is also possible for the carrier layer to be arranged between the layer that enhances the color-shifting effect and the layer of color-shifting pigments or the liquid crystal layer.
An dieser Stelle sei daraufhingewiesen, dass zwischen der zumindest einen den Farbkippeffekt verstärkenden Schicht und der Trägerschicht und/oder der zumindest einen Schicht aus farbkippenden Pigmenten oder der zumindest einen Flüssigkristallschicht je eine oder mehrere Zwischenschichten angeordnet sein können. 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 pointed out that one or more intermediate layers can be arranged between the at least one layer that enhances the color-shifting effect and the carrier layer and / or the at least one layer of color-shifting pigments or the at least one liquid crystal layer. 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 several partial layers.
Darüber hinaus kann vorgesehen sein, dass der farbkippende Dünnschichtaufbau zumindest eine Absorberschicht und zumindest eine Distanzschicht aus einem dielektrischen Material aufweist.In addition, it can be provided that the color-shifting thin-layer structure has at least one absorber layer and at least one spacer layer made of a dielectric material.
Vorteilhaft ist auch eine Ausprägung, gemäß welcher vorgesehen sein kann, dass der farbkippende Dünnschichtaufbau zumindest eine Reflexionsschicht aufweist, wobei die Distanzschicht zwischen Reflexionsschicht und Absorberschicht angeordnet ist.An embodiment is also advantageous, according to which it can be provided that the color-shifting thin-layer structure has at least one reflective layer, the spacer layer being arranged between the reflective layer and the absorber layer.
Gemäß einer Weiterbildung ist es möglich, dass eine Trägerschicht aus Kunststoff, insbesondere aus einem lichtdurchlässigen und/oder thermoplastischen Kunststoff, ausgebildet ist, wobei die Trägerschicht bevorzugt zumindest eines der Materialien aus der Gruppe Polyimid (PI), Polypropylen (PP), monoaxialorientiertem 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, Polybutylenterephthalat (PBT), Polyethylenterephthalat (PET), Polyamid (PA), Polycarbonat (PC),Cycloolefincopolymere (COC), Polyoximethylen (POM), Acrylnitril-butadien-styrol (ABS), Polyvinylcholrid (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.According to a further development, it is possible for a carrier layer to be formed from plastic, in particular from a translucent and / or thermoplastic plastic, the carrier layer preferably at least one of the materials from the group of 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), polyvinylcholride (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.
Ferner kann es zweckmäßig sein, wenn die Trägerschicht eine Dicke von 5 µm bis 1000 µm, besonders bevorzugt eine Dicke von 8 µm bis 50 µm, aufweist.Furthermore, it can be expedient if the carrier layer has a thickness of 5 μm to 1000 μm, particularly preferably a thickness of 8 μm to 50 μm.
Darüber hinaus kann vorgesehen sein, dass auf der zumindest einen Flüssigkristallschicht oder der zumindest einen Schicht aus farbkippenden Pigmenten die den Farbkippeffekt verstärkende Schicht, insbesondere eine Schicht aus dunkler Farbe und/oder eine Schicht aus Metalloxiden wie beispielsweise unterstöchiometrisches Aluminiumoxid, aufgebracht ist, sodass die zumindest eine Schicht aus farbkippenden Pigmenten oder die zumindest eine Flüssigkristallschicht zwischen der zumindest einen den Farbkippeffekt verstärkenden Schicht und einer Trägerschicht angeordnet ist, oder dass die zumindest eine den Farbkippeffekt verstärkende Schicht zwischen der Trägerschicht und der zumindest einen Schicht aus farbkippenden Pigmenten oder der zumindest einen Flüssigkristallschicht angeordnet ist, oder dass die Trägerschicht zwischen der zumindest einen den Farbkippeffekt verstärkenden Schicht und der zumindest einen Schicht aus farbkippenden Pigmenten oder der zumindest einen Flüssigkristallschicht angeordnet ist.In addition, it can be provided that on the at least one liquid crystal layer or the at least one layer of color-shifting pigments, the layer that enhances the color-shifting effect, in particular a layer of dark color and / or a layer of metal oxides such as substoichiometric aluminum oxide, is applied so that the at least a layer of color-shifting pigments or the at least one liquid-crystal layer is arranged between the at least one layer that enhances the color-shift effect and a carrier layer, or that the at least one layer that enhances the color-shifting effect is arranged between the carrier layer and the at least one layer of color-shifting pigments or the at least one liquid crystal layer or that the carrier layer is between the at least one color-shifting effect enhancing layer and the at least one layer of color-shifting pigments or the at least one liquid crystal layer is organized.
