Abstract
A method is provided for manufacturing pigments of defined size and shape, and to pigments manufactured accordingly. The method has the steps of: a) producing a three-dimensional surface structure on a substrate, where surface regions are formed each having a gradient extending obliquely to a base level of the surface structure, and are arranged in columns which are offset relative to one another; b) applying a pigment material layer on the surface structure; c) releasing the pigment material layer from the surface structure and producing pigments.
