Abstract
A process for producing pigments having a defined size and shape and also pigments produced by this process. The process has the steps: a) production of a three-dimensional surface structure on a substrate, with surface regions which are in each case partly bounded by a plurality of three-dimensional structural elements and are arranged in gaps being formed; b) application of a pigment material layer to the surface structure; c) detachment of the pigment material layer from the surface structure and production of pigments.
