Abstract
A method is provided for producing platelet-shaped pigments, including the steps of: providing a film structure which has a carrier substrate, a water-soluble release layer and a pigment material layer; mechanically disrupting the pigment material layer, which is present in the film structure, at specific locations; soaking the film structure with aqueous solution; subjecting the film structure to a mechanical force so that the pigment material layer is detached from the carrier substrate as a plurality of pigments according to the ruptures present at the specific locations.
