Abstract

Die Erfindung betrifft ein Sicherheitselement (1) zur Erhöhung des Fälschungsschutzes von Sicherheitspapieren, Wertdokumenten, Ausweiskarten oder Produkten jeglicher Art, wobei das Sicherheitselement aus einem Substrat besteht, dessen Oberfläche auftreffendes Licht diffus reflektiert, und aus einer Beschichtung (5) besteht, die die Oberfläche des Substrats mindestens teilweise bedeckt, wobei die Oberfläche der Beschichtung auftreffendes Licht mindestens teilweise spiegelnd reflektiert. Erfindungsgemäß weist die Beschichtung (5) des Sicherheitselements (1) Bereiche (6) mit verminderter Schichtdicke und/ oder mit Aussparungen auf, wobei diese Bereiche (6) für einen Betrachter bei bestimmten Betrachtungswinkeln keinen oder nur einen geringfügig erkennbaren und bei anderen Betrachtungswinkeln einen deutlich erkennbaren Kontrast gegenüber den umliegenden Bereichen der Beschichtung ohne verminderte Schichtdicke bzw. ohne Aussparungen aufweisen. Abhängig vom Betrachtungswinkel und dem Winkel des einfallenden Lichtes erscheinen die Bereiche (6) mit verminderter Schichtdicke und/ oder mit Aussparungen gegenüber der spiegelnd reflektierenden Umgebung hell oder dunkel oder verschwinden für den Betrachter nahezu vollständig.

Figure imgaf001
The invention relates to a security element (1) for increasing the protection against counterfeiting of security papers, documents of value, identification cards or products of any kind, wherein the security element consists of a substrate whose surface diffusely reflects incident light and consists of a coating (5) covering the surface the substrate is at least partially covered, wherein the surface of the coating reflects incident light at least partially specular. According to the invention, the coating (5) of the security element (1) has areas (6) with reduced layer thickness and / or with recesses, these areas (6) being obscure or only slightly recognizable to a viewer at certain viewing angles and clearly visible at other viewing angles have visible contrast to the surrounding areas of the coating without reduced layer thickness or without recesses. Depending on the viewing angle and the angle of the incident light, the regions (6) with a reduced layer thickness and / or recesses with respect to the specularly reflecting environment appear light or dark or disappear almost completely for the viewer.
