Abstract

Die Erfindung betrifft ein lasermarkierbares Sicherheitselement zur Absicherung von Wertgegenständen. Erfindungsgemäß enthält das Sicherheitselement einen lasermarkierbaren Merkmalsstoff mit Kern-Hülle-Teilchen (20; 30), wobei eines der Materialien (24, 32) von Kern und Hülle die Strahlung eines Markierungslaser absorbiert und das andere der Materialien (22, 34) von Kern und Hülle die Strahlung des Markierungslasers nicht absorbiert.
