Abstract:
1. A multi-layer body having a replication layer and at least one partially shaped first layer arranged on the replication layer, wherein a diffractive first relief structure is shaped in a first region of the replication layer and a diffractive second relief structure is shaped in a second region of the replication layer, the diffractive first relief structure is not shaped in the replication layer in the second region of the replication layer, and the first layer is entirely removed from one of the first or second region in a manner determined by the arrangement of the diffractive first relief structure so that the first layer is disposed in accurate register relationship with the first relief structure in the first region but not in the second region or in accurate register relationship with the second relief structure in the second region but not in the first region, and wherein each of the diffractive first and second relief structures comprises a plurality of peaks and troughs formed in the respective first and second regions of the replication layer whereby the first layer is deposited locally in varying thicknesses due to the respective diffractive relief structure on which it is disposed, such that the first layer has a transmission property influenced by the respective diffractive relief structure on which it is disposed, and wherein the first relief structure has a greater relief depth than the second relief structure.
