Abstract
Die Erfindung betrifft ein Schutzelement zur Echtheitsprüfung eines Schutzgegestandes mit einer Unterlage und einer metallisierten Schicht. Damit das Schutzelement die Zuverlässigkeit beider Fälschungssicherheit erhöht, fertigungsgünstig herstellbar und die Kontrolle mit Hilfe von einfachen physikalischen Einrichtungen zulässt, ist nach der Erfindung vorgesehen, dass die genannte metallisierte Schicht eine ein- oder mehrlagige metallisierte Inselschicht oder die Schicht aus einem granulierten Metall darstellt, dass diese Schicht eine nichtlineare Abhängigkeit von den elektrophysikalischen Eigenschaften aufweist, wenn sie unter Einwirkung eines schwachen elektrischen Gleich- oder Wechselstromfeldes steht, dass diese Schicht zusätzlich eine dielektrische Schutzschicht aufweist, welche oberhalb der erwähnten metallisierten Schicht aufgetragen ist und dass als erkennbares Merkmal der Echtheit des Schutzgegenstandes die nichtlineare Leitfähigkeit des Schutzelements dient, welche mittels der Messung der Leitfähigkeit des Schutzelements bei zwei unterschiedlichen Amplituden des genannten an das Schutzelement angelegten elektrischen Feldes bestimmt ist. The invention relates to a protective element for checking the authenticity of a Schutzgegestandes with a pad and a metallized layer. In order for the protective element to increase the reliability of both security against counterfeiting, to manufacture with low production costs and to allow control by means of simple physical means, it is provided according to the invention that said metallized layer represents a single-layered or multi-layered metallized island layer or the layer of a granulated metal this layer has a non-linear dependence on the electrophysical properties, when exposed to a weak DC or AC electric field, that this layer additionally has a dielectric protective layer, which is applied above said metallized layer and that as a recognizable feature of the authenticity of the subject the non-linear conductivity of the protective element is used, which by means of the measurement of the conductivity of the protective element at two different amplitudes of said applied to the protective element electric field is determined.
