Definitions
- the invention relates to a security element for value documents, such as banknotes, securities and the like, which consists of a plastic film laminate and has an integrated authenticity check.
- Security elements for value documents, banknotes or securities are known. These security elements have a wide variety of security features and can be applied to the value documents or completely or partially embedded in the substrate of the value documents.
- Applied security elements generally have less protection against counterfeiting because they are easily accessible on the surface of the value document and tampering is easier to perform.
- the object of the invention was to provide a security element which has absolute protection against counterfeiting and is visually recognizable on the surface of a value document.
- the invention therefore provides a security element according to claim 1.
- Suitable as a base and / or top layer films are flexible plastic films, for example, from PI, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PSU, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM , ABS, PVC, PTFE, ETFE (Ethylene tetrafluoroethylene), PFA (tetrafluoroethylene-perfluoropropyl vinyl ether fluorocopolymer), MFA (tetrafluoromethylene-perfluoropropyl vinyl ether fluorocopolymer), PTFE (polytetrafluoroethylene), PVF (polyvinyl fluoride), PVDF (polyvinylidene fluoride), and EFEP (ethylene-tetrafluoroethylene-hexafluoropropylene). fluoroterpolymer).
- the plastic films preferably have a thickness of 5 to 700 .mu.m, preferably 5 to 200 .mu.m, particularly preferably 5 to 50 .mu.m.
- base or cover layer may also consist of paper or composites of paper, for example composites with plastics having a weight per unit area of 20 to 500 g / m 2 , preferably 40 to 200 g / m 2 .
- Base and cover layers are laminated against each other to form a laminate in such a way that they are connected to one another in strip form at least at their longitudinal edges. Between these laminated longitudinal edges, an open channel is created, which opens up a multitude of possibilities for integrating security elements.
- At least one of the mutually laminated films or one of the substrates already has one or more security features.
- security features in the form of characters, structures, lines, symbols, texts, forms and the like come into question as security features.
- these characters, structures, lines, symbols, texts, shapes are in the form of micro-prints or embossings.
- a sliding element is then inserted into the open channel formed between the longitudinal edges of the laminate, which is also provided with security features corresponding to the security feature or features present on one or both plastic films of the laminate.
- the security features of this sliding element can be brought into register with the safety features present on the base layer or cover layer or both layers of the laminate, or new or completed forms, images, characters, symbols, logos and the like become recognizable.
- the sliding element may consist of the same or different material as the base or cover layer of the laminate.
- the sliding element can also consist of a metal foil, for example an Al, Cu, Sn, Ni, Fe or stainless steel foil with a thickness of 5-200 ⁇ m, preferably 10 to 80 ⁇ m, particularly preferably 20-50 ⁇ m.
- the film can also be surface-treated, coated or laminated, for example, with plastics or painted.
- pigmented or unpigmented paint or coating compositions can be used.
- the pigments there may be used any known pigments, for example, inorganic-based pigments such as titanium dioxide, zinc sulfide, kaolin, ITO, ATO, FTO, aluminum, chromium and silicon oxides, or organic-based pigments such as phthalocyanine blue, i-indolidine yellow, dioxazine violet and the like It is also possible to use colored and / or encapsulated pigments in chemically, physically or reactively drying binder systems. Examples of suitable dyes are 1,1- or 1,2-chromium-cobalt complexes.
- Solvent-containing paint and / or paint systems aqueous and solvent-free paint systems can be used.
- Suitable binders are various natural or synthetic binders.
- paints or lacquers with luminescent for example phosphorescent or fluorescent properties
- lacquers with a defined refractive index or thermochromic colors can be applied.
- optical features on base, cover layer and / or sliding element complementary optical pattern for example, a rainbow color gradient
- symbols, characters, images, logos and the like can be generated.
- additive or subtractive color mixtures can be created which further increase the security against counterfeiting.
- the paint to be applied or the paint to be applied for example graphite, carbon black, conductive organic or inorganic polymers, metal pigments (for example copper, aluminum, silver, gold, iron, chromium and the like), metal alloys such as copper Zinc or copper-aluminum or amorphous or crystalline ceramic pigments such as ITO, ATO, FTO and the like may be added.
- metal pigments for example copper, aluminum, silver, gold, iron, chromium and the like
- metal alloys such as copper Zinc or copper-aluminum or amorphous or crystalline ceramic pigments such as ITO, ATO, FTO and the like
- doped or non-doped semiconductors such as, for example, silicon, germanium or doped or undoped polymeric semiconductors or ion conductors, such as amorphous or crystalline metal oxides or metal sulfides, as an additive.

Als Merkmal mit elektrischen Eigenschaften kann auch eine partielle Metallschicht aufgebracht werden, wobei die partielle Aufbringung mittels eines Ätzverfahrens (Aufbringung einer vollflächigen Metallschicht und anschließende partielle Entfernung durch Ätzen) oder mittels eines Demetallisierungsverfahrens erfolgen kann.As a feature with electrical properties, a partial metal layer can also be applied, whereby the partial application can take place by means of an etching process (application of a full-area metal layer and subsequent partial removal by etching) or by means of a demetallization process.
Bei Verwendung eines Demetallisierungsverfahrens wird in einem ersten Schritt eine in einem Lösungsmittel lösliche Farbe (gegebenenfalls in Form einer inversen Codierung) aufgebracht, anschließend wird, gegebenenfalls nach Aktivierung des Trägersubstrats durch eine Plasma- oder Coronabehandlung, die metallische Schicht aufgebracht, worauf die lösliche Farbschicht durch Behandlung mit einem geeigneten Lösungsmittel samt der in diesen Bereichen vorhandenen Metallisierung abgelöst wird.When using a demetallization process in a first step, a solvent-soluble ink (optionally in the form of an inverse coding) is applied, then, optionally after activation of the carrier substrate by a plasma or corona treatment, the metallic layer is applied, whereupon the soluble ink layer Treatment with a suitable solvent, including the existing metallization in these areas is replaced.

Der Code kann sich dabei durch Einbringung bzw. Verschiebung des Schiebeelements im Kanal so ändern, dass ein neuer Code entsteht, der wiederum maschinell auslesbar ist. Zur Verifikation des Sicherheitselements kann also das Schiebeelement beispielsweise nacheinander in mehrere verschiedene Positionen zwischen Basis und Deckschicht gebracht werden und an jeder Position der Code ausgelesen werden, sodass sich eine deutlich höhere Fälschungssicherheit als bei einfachen Codierungen ergibt.The code can be changed by introducing or shifting the sliding element in the channel so that a new code is created, which in turn is machine readable. For verification of the security element, therefore, the sliding element can, for example, be successively brought into a plurality of different positions between base and cover layer and the code read out at each position, resulting in a significantly higher security against forgery than with simple codes.

Furthermore, it is also possible to use a high refractive index (HRI) layer, ie a layer having a higher refractive index than that of the lacquer forming the optically active layer, as a reflection layer.
Die Reflexionsschicht kann beispielsweise auf der Basisschicht, die optisch aktive Schicht auf dem Schiebeelement angeordnet sein. Ist die optisch aktive Schicht auf der Deckfolie angeordnet, kann die Reflexionsschicht beispielsweise auf dem Schiebeelement angeordnet sein, oder das Schiebeelement aus einer Metallfolie bestehen.The reflection layer can be arranged, for example, on the base layer, the optically active layer on the sliding element.
