Gegenstand der Erfindung ist daher ein Sicherheitselement gemäß Anspruch 1.The invention therefore provides a security element according to claim 1.

Die im Register gedruckten Schichten sind durch Abstandsschichten getrennt.The layers printed in the register are separated by spacer layers.

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

Die Trägersubstrate können zusätzlich eine Lackschicht aufweisen, die unstrukturiert oder strukturiert, beispielsweise geprägt sein oder Beugungsgitter aufweisen kann. Die Lackschicht kann beispielsweise eine haftende Lackschicht oder eine releasefähige Transferlackschicht sein, sie kann durch Strahlung, beispielsweise UV-Strahlung, thermisch oder reaktiv vernetzt oder vernetzbar sein und zusätzliche Eigenschaften wie z.B. kratzfeste und/oder antistatische Ausrüstung oder chemische Beständigkeit besitzen. Geeignet sind sowohl wässrige als auch lösungsmittelhältige Lacksysteme, insbesondere auch Lacksysteme auf Basis PE - Acrylat, PET-Acrylat, Urethan-Acrylat, PVC, PMMA oder Epoxyacrylat.The carrier substrates may additionally have a lacquer layer which may be unstructured or structured, for example embossed or may have diffraction gratings. The lacquer layer can be, for example, an adhesive lacquer layer or a release-capable transfer lacquer layer, it can be thermally or reactively crosslinked or crosslinkable by radiation, for example UV radiation, and additional properties, such as e.g. Scratch-resistant and / or antistatic equipment or have chemical resistance. Both aqueous and solvent-based coating systems are suitable, in particular coating systems based on PE acrylate, PET acrylate, urethane acrylate, PVC, PMMA or epoxy acrylate.

Auf das Trägersubstrat bzw. auf gegebenenfalls auf dem Trägersubstrat bereits vorhandene Beschichtungen wird eine partielle Schicht aus einer vorzugsweise opaken Farbe oder einem Lack aufgedruckt. In einer oder mehreren weiteren Schichten werden dann registergenau weitere Elemente aufgebracht und zwar in der Weise, dass sich die Elemente bei Betrachtung im Durchlicht zu einem optisch erkennbaren Merkmal ergänzen.A partial layer of a preferably opaque ink or lacquer is printed on the carrier substrate or on coatings which may already be present on the carrier substrate. In one or more further layers further elements are then applied in register and in such a way that the elements complement each other when viewed in transmitted light to an optically recognizable feature.

Ein Beispiel für eine derartige Schichtanordnung ist in Fig. 1 dargestellt.An example of such a layer arrangement is in Fig. 1 shown.

Dabei können die erste partielle Schicht sowie die im Register gedruckten Schichten entweder gleich sein oder unterschiedlich. Die Schichten können dabei entweder metallisch oder metallisch erscheinende Schichten, schwarze oder farbige Schichten sein. Dabei können insbesondere auch in den einzelnen Schichten unterschiedliche Farben verwendet werden, wobei je nach Wahl der Farben bei Betrachtung unter unterschiedlichen Betrachtungswinkeln entweder charakteristische Mischfarben ergeben können oder es zu einer Lichtauslöschung kommt.The first partial layer as well as the layers printed in the register can either be the same or different. The layers can either metallic or metallic appearing layers, black or colored layers. In this case, different colors can also be used in particular in the individual layers, whereby, depending on the choice of colors when viewed at different viewing angles, either characteristic mixed colors can result or a light extinguishment occurs.

Beispiele für derartige Schichtaufbauten sind in den Fig. 2 und 3 dargestellt.Examples of such layer structures are in the FIGS. 2 and 3 shown.

Dabei bedeutet 1 das Trägersubstrat, 2 bspw. eine rote Schicht, 3 bspw. eine grüne Schicht und 4 eine Abstandschicht.1 means the carrier substrate, 2 for example a red layer, 3 for example a green layer and 4 a spacer layer.

Besonders geeignet sind Fe(II)- und Fe(III)-Oxide, Barium- bzw. Cobaltferrite, seltene Erden und dergleichen.To adjust the magnetic properties, paramagnetic, diamagnetic and also ferromagnetic substances, such as iron, nickel, barium, and cobalt or their compounds or salts (for example, oxides or sulfides) can be used. Especially suitable are Fe (II) and Fe (III) oxides, barium or cobalt ferrites, rare earths and the like.

Es ist auch möglich der verwendeten Magnetfarbe, beispielsweise Ruß oder Graphit zuzusetzen, wodurch eine gleichzeitig magnetische als auch elektrisch leitfähige Schicht auch in definierter Codierung herstellbar ist.It is also possible to use the magnetic ink used, for example, carbon black or graphite, whereby a simultaneously magnetic and electrically conductive layer can also be produced in a defined coding.

Diese im Register gedruckten Schichten sind durch transparente Abstandsschichten getrennt.These layers printed in the register are separated by transparent spacer layers.

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

Das Folienmaterial zeigt bei senkrechter Betrachtung im Durchlicht dann das in mehreren Schichten aufgebrachte sich zu Mustern, Zeichen, Buchstaben und dergleichen ergänzende Merkmal. Wird das Folienmaterial nicht senkrecht, sondern in einem Winkel < 90° betrachtet, so ergeben sich zusätzliche Transmissionswege für das durchdringende Licht. Der Kontrast zwischen der opaken mehrschichtigen Bedruckung und den Aussparungen wird vermindert, je nach verwendeter Abstandsschicht treten zusätzliche definierte Effekte, beispielsweise optische Effekte (Lumineszenz bei Anregung, metallischer Glanz) optisch variable oder optisch aktive Effekte auf.The film material shows when viewed vertically in transmitted light then applied in several layers to patterns, characters, letters and like additional feature. If the film material is not viewed vertically, but at an angle <90 °, additional transmission paths for the penetrating light result. The contrast between the opaque multi-layer printing and the recesses is reduced; depending on the spacer layer used, additional defined effects occur, for example optical effects (luminescence upon excitation, metallic luster), optically variable or optically active effects.

Ferner können auch zusätzliche Schichten mit elektrisch leitfähigen und/oder magnetischen Eigenschaften auf dem Substrat vorhanden sein, oder anschließend aufgebracht werden.Furthermore, additional layers with electrically conductive and / or magnetic properties can also be present on the substrate, or can subsequently be applied.
