Security element |
| abstract |
The invention relates to a security element which comprises a substrate and an optically variable multilayer structure and which can be written by the action of a laser, the multilayer structure comprising a spacer layer and a phase change-material layer. The security element thus allows the generation of high-resolution two-color image information which is more difficult to reproduce. |
