| 摘要 |
The invention relates to a security element, preferably for value documents, comprising at least one region with a holographic element which reconstructs a holographic optical image under certain observation conditions. Said region comprises sub-regions which do not take part in the reconstruction of the holographic optical image and which represent recognisable information. The information represented by the sub-regions is essentially only recognisable under those observation conditions in which the holographic optical image ca n also be observed. |
