Abstract
A method for producing pigments comprises the steps of creating a first layer on a substrate, structuring the first layer and detaching the pigments from the substrate. In the present case, the first layer is a crack-forming layer, so that the first layer is structured by the arising of cracks. Prior to detaching the pigments, a pigment layer is applied onto the first layer structured by the cracks.
