Aufgabe der Erfindung ist die Bereitstellung von Sicherheitsetementen mit kombinierten maschinell erkennbaren Sicherheitsmerkmalen.The object of the invention is the provision of security elements with combined machine-recognizable security features.

Gegenstand der Erfindung ist daher ein Sicherheitselement gemäß Anspuch 1.The subject of the invention is therefore a security element according to claim 1.

Die Schicht des Sicherheitselements wird auf ein flexibles Trägersubstrat aufgebracht.The layer of the security element is applied to a flexible carrier substrate.

Als Trägersubstrat kommen beispielsweise Trägerfolien vorzugsweise flexible Kunststofffolien, beispielsweise aus PI, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PSU, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM, ABS, PVC in Frage. Die Trägerfolien weisen vorzugsweise eine Dicke von 5 - 700 µm, bevorzugt 8 - 200 µm, besonders bevorzugt 12 - 50 µm auf.For example, carrier foils are preferably flexible plastic foils, for example, PI, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PSU, 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 8 to 200 .mu.m, more preferably 12 to 50 .mu.m.

Femer können als Trägersubstrat auch Metallfolien, beispielsweise Al-, Cu-, Sn-, Ni-, Fe- oder Edelstahlfolien mit einer Dicke von 5 - 200 µm, vorzugsweise 10 bis 80 µm, besonders bevorzugt 20 - 50 µm dienen. Die Folien können auch oberflächenbehandelt, beschichtet oder kaschiert beispielsweise mit Kunststoffen oder lackiert sein.Furthermore, metal foils, for example Al, Cu, Sn, Ni, Fe or stainless steel foils having a thickness of 5-200 μm, preferably 10 to 80 μm, particularly preferably 20-50 μm, may serve as the carrier substrate. The films can also be surface-treated, coated or laminated, for example, with plastics or painted.

Femer können als Trägersubstrate auch Papier oder Verbunde mit Papier, beispielsweise Verbunde mit Kunststoffen mit einem Flächengewicht von 20 - 500 g/m2, vorzugsweise 40 - 200 g/m2. verwendet werden.Furthermore, paper or composites with paper, for example composites with plastics having a basis weight of 20 to 500 g / m 2 , preferably 40 to 200 g / m 2, may also be used as the carrier substrates. be used.

Femer können als Trägersubstrat auch mehrschichtige Kunststofffolien oder Folienverbunde, beispielsweise Verbunde aus Metall - und Kunststofffolien verwendet werden.Furthermore, multilayer plastic films or film composites, for example composites of metal and plastic films, can also be used as the carrier substrate.

Zur Einstellung elektrischer Eigenschaften, beispielsweise Leitfähigkeit können beispielsweise Ruß, Metallpigmente (beispielsweise Kupfer, Aluminium, Silber, Gold, Eisen, Chrom und dergleichen), zugegeben werden.To adjust electrical properties, for example conductivity, for example carbon black, metal pigments (for example copper, aluminum, silver, gold, iron, chromium and the like) may be added.

Zur Einstellung der magnetischen Eigenschaften können ferromagnetische Stoffe, wie Eisen, Nickel und Cobalt oder deren Verbindungen oder Salze (beispielsweise Oxide ) verwendet werden.To adjust the magnetic properties, ferromagnetic substances such as iron, nickel and cobalt or their compounds or salts (for example oxides) can be used.

Besonders ist zur Einstellung der magnetischen Eigenschaften eine Magnetpigmentfarbe auf Basis von oxidischen Pigmenten wie beispielsweise Fe2O3 oder Fe3O4, Metallpigmenten wie Eisen, Nickel, Cobalt oder Chrom und/oder deren Legierungen, z.B.: Cr-Ni-Stahl (Edelstahl), Barium- bzw. Cobalt-Ferrite oder ähnliche.To adjust the magnetic properties, a magnetic pigment ink based on oxidic pigments such as, for example, Fe 2 O 3 or Fe 3 O 4 , metal pigments such as iron, nickel, cobalt or chromium and / or their alloys, for example: Cr-Ni steel (stainless steel ), Barium or cobalt ferrites or the like.

Diese Pigmente können hart- oder weichmagnetisch sein.These pigments can be hard or soft magnetic.

Die Pigmente sind in einer wässrigen oder lösungsmittelhaltigen Acrylat-Polymerdispersion (mit einem MG von 150.000 - 300.000) bzw. in einer Acrylat-Styrol- oder Acrylat-Urethan-Polymerdispersion dispergiert. Als Lösungsmittel kommen dabei Wasser, Alkohole, wie i-Propanol, oder Methoxypropanol, Ester wie Ethylacetat, Ketone wie Methylethylketon und deren Mischungen in Frage.The pigments are dispersed in an aqueous or solvent-containing acrylate polymer dispersion (with a MW of 150,000-300,000) or in an acrylate-styrene or acrylate-urethane polymer dispersion. Suitable solvents include water, alcohols such as i-propanol, or methoxypropanol, esters such as ethyl acetate, ketones such as methyl ethyl ketone and mixtures thereof.

Dabei werden auch verschiedene Eigenschaften durch Zufügen verschiedener oben genannter Zusätze kombiniert. So ist es möglich angefärbte und/oder elektrisch leitfähige Magnetpigmente zu verwenden.Various properties are also combined by adding various additives mentioned above. It is thus possible to use colored and / or electrically conductive magnetic pigments.

So kann beispielsweise eine derartige Magnetpigmentfarbe durch Wahl der geeigneten Pigmente und entsprechende Konzentration intrinsisch leitfähig eingestellt werden: So können beispielsweise Fe3O4, Russ, oder Metalle, leitfähige ferromagnetische Pigmente, leitfähige Stahlpigmente, ggf. in einer leitfähigen Polymermatrix zugegeben werden. Die Konzentration der Pigmente kann etwa 0,01 - 30 % betragen.Thus, such a magnetic pigment color can be adjusted intrinsically conductive by selection of suitable pigments and appropriate concentration, for example: For example, Fe 3 O 4, carbon black, or metals, conductive ferromagnetic pigments, conductive steel pigments are optionally added in a conductive polymer matrix. The concentration of the pigments may be about 0.01-30%.

Durch Zusatz von leitfähigen Materialien, beispielsweise, Ruß, Graphit oder Silber weist die Magnetpigmentfarbe zusätzlich elektrisch leitfähige Eigenschaften auf.By adding conductive materials, for example, carbon black, graphite or silver, the magnetic pigment ink additionally has electrically conductive properties.

Dadurch können zwei verschiedene funktionelle Merkmale in einer Schicht aufgebracht werden.As a result, two different functional features can be applied in one layer.

Zur Einstellung eines bestimmten Farbtons werden die Magnetpigmente aber durch Belegen mit Metallen, beispielsweise durch Bedampfen oder chemische Abscheidung, durch Galvanisieren oder Coaten eingefärbt.To set a particular hue, however, the magnetic pigments are colored by coating with metals, for example by vapor deposition or chemical deposition, by electroplating or coating.

Die Polymere werden in Form einer Dispersion in einem Dispersionsmittel auf das Trägermaterial aufgebracht. Als Dispersionsmittel kommen beispielsweise inerte Lösungsmittel vorzugsweise wässrige Lösungsmittel oder Alkohole, wie i-Propanol in Frage. Gegebenenfalls können den Polymerdispersionen auch Matrixpolymere, beispielsweise wasserlösliche Polyester, Polyurethane, Polystyrolsulfonate, Polyacrylate oder Ethylenacrylatcopolymere als Matrixpolymere zugesetzt werden.The polymers are applied to the support material in the form of a dispersion in a dispersing agent. Suitable dispersants are, for example, inert solvents, preferably aqueous solvents or alcohols, such as i-propanol. If desired, it is also possible to add matrix polymers, for example water-soluble polyesters, polyurethanes, polystyrene sulfonates, polyacrylates or ethylene acrylate copolymers, as matrix polymers to the polymer dispersions.

Beispielsweise kann Polyethylendioxythiophen mit Polystyrolsulfonat als Matrixpolymer besonders vorteilhaft verwendet werden.For example, polyethylene dioxythiophene can be used particularly advantageously with polystyrene sulfonate as the matrix polymer.

Die Partikelgröße der Polymere in der Dispersion beträgt vorzugsweise 20 - 500 nm.The particle size of the polymers in the dispersion is preferably 20-500 nm.

Die Aufbringung der Schicht kann passergenau zu einer und/oder mehreren bereits auf dem Trägersubstrat vorhandenen Schichten erfolgen, sie kann aber auch vollständig und/oder teilweise überlappend zu einer und/oder mehreren bereits vorhandenen Schichten erfolgen.The application of the layer can be carried out in registration with one and / or several layers already present on the carrier substrate, but it can also be complete and / or partially overlapping to one and / or several already existing layers.

Zur passergenauen Aufbringung ist die Trägerbahn mit Registermarken und Steuerlinien versehen und wird über eine vorgelagerte Messeinrichtung beispielsweise Sensoren, zwischen zwei oder mehreren Registermarken der Länge nach vermessen und anschließend zwischen zwei oder mehreren angesteuerten Zuggruppen auf die notwendige Registerlänge eingestellt Anschließend wird die Trägerbahn von einem Regelkreis, insbesondere einen Registerregler über eine Registerwalze vor dem ersten Druckwerk registergenau eingesteuert, wobei das Seitenregister über eine Bahnsteuerung vorgesteuert und über einen Schwenkrahmen eingesteuert wird, worauf der Druck der Schicht erfolgt.For register-accurate application, the carrier web is provided with register marks and control lines and is via an upstream measuring device, for example, sensors, between two or more register marks the Measured lengthwise and then set to the required register length between two or more controlled train groups Subsequently, the carrier web is registered by a control circuit, in particular a register controller via a register roller in front of the first printing unit register accurate, the page register is pre-controlled via a path control and controlled by a swing frame , whereupon the printing of the layer takes place.

Gegebenenfalls kann die Trägerbahn zwischen Zuggruppen gedehnt oder beispielsweise durch Erwärmen mit einem Konvektionstrockner oder IR-Strahler auf die gewünschte Länge schrumpft werden.Optionally, the carrier web can be stretched between pull groups or be shrunk to the desired length, for example, by heating with a convection dryer or IR radiator.
