Patent ID: 8053146

Claim:
A process for the production of a multi-layer body having a partially shaped first layer, wherein a diffractive first relief structure is shaped in a first region of a replication layer of the multi-layer body, and wherein the first layer is applied to the replication layer in the first region and in a second region in which the first relief structure is not shaped in the replication layer, with a constant surface density with respect to a plane defined by the replication layer, and wherein the diffractive first relief structure in the first region has a relief structure such that the thickness of the material of the first layer is deposited locally in varying thicknesses such that the transmission properties in the first and second regions differ, and wherein either a photosensitive layer is applied to the first layer or the replication layer comprises a photosensitive washing mask, and wherein 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 wherein 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.
