| 摘要 |
The invention relates to a security element for security papers, value documents, and other data carriers, comprising a substrate that contains an optically variable surface pattern (76) in a surface region (74). According to the invention, said optically variable surface pattern (76), which shows different representations when illuminated and/or viewed from different directions, consists of an at least locally periodic arrangement of reflective elements (72-j, 72-k) that have a substantially radiation-optical effect and are vertically offset from each other in an aperiodic manner above the surface region (74). |
