摘要:
The present invention discloses a security element comprising a transparent substrate and a magnetically oriented image coating on said substrate, wherein said image coating is preferably laid out such as to show a 3-dimensional effect, appearing in positive or negative relief respectively, if observed form the recto- or the verso side, respectively. The security element can be easily identified by the unaided eye, by just turning around the document and observing the angle-dependent image on either side. On the other hand, the security element cannot be reproduced by scanning or copying the document.
