摘要：
A method for producing pigments having a specified contour, comprises the steps of creating a pigment layer on a starting substrate; detaching from the starting substrate; and structuring the pigment layer into a plurality of the pigments; characterized by bringing into contact the pigment layer with an intermediate substrate, wherein the pigment layer adheres at least in sections to the intermediate substrate; and separating intermediate substrate and starting substrate.
