摘要:
Described is a process for the production of a multi-layer body having a volume hologram with at least two different items of image information, wherein a photosensitive layer (46) of the multi-layer body is directly or with the interposition of a transparent optical medium (44s, 45) brought into contact with the front side of a master (44), in which interlaced regions with different asymmetrical surface structures or kinoform structures are shaped, which embody the at least two different items of image information. The photosensitive layer (46) and the master are exposed with a coherent light beam (47) whereby a volume hologram is formed in the photosensitive layer (46). Also described are a master for the production of the multi-layer body and a security element having said multi-layer body.
