Patent ID: 7821716

Claim:
A process for the production of a multi-layer body having a partially shaped first layer, the process comprising the steps of: shaping a diffractive first relief structure having individual structure elements with a depth-to-width ratio of >0.3 in a first region of a replication layer of the multi-layer body; applying the first layer 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, said first layer being applied with a constant surface density with respect to a plane defined by the replication layer, and wherein the diffractive relief structure in the first region influences physical properties of the first layer, so that the physical properties of the first layer differ in the first and second regions; and partially removing the first layer in a manner determined by the first relief structure so that the first layer is removed from only one of the first region or the second region.
