| 20120038988 | Multi-layer body and process for the production of a multi-layer body - A multi-layer body having a partially shaped first layer and a diffractive first relief structure shaped in a first region of a replication layer. The first layer is applied to the replication layer in the first region and, in a second region, a photosensitive layer is applied to the first layer or a photosensitive washing mask is applied thereto as a replication layer. The photosensitive layer or the washing mask is exposed through the first layer so that the photosensitive layer or washing mask is exposed differently due to the first relief structure in the first and in the second regions, and the first layer is removed using the exposed photosensitive layer or washing mask as a mask layer in the first region but not in the second region or in the second region but not in the first region. | 02-16-2012 |
