Abstract: 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.

Abstract: A platelet-shaped pigment with a layer construction comprises the following layers in the order, optionally a carrier substrate; a transparent embossing lacquer layer with an embossed relief structure; a reflection-increasing coating which follows the relief structure and forms a reflecting microstructure, wherein the reflecting microstructure is present in the form of a mosaic of a multiplicity of reflecting mosaic elements and the reflecting mosaic elements do not reflect the incident light in the direction of the specular reflex, regarding the plane of the platelet, but in a spatial direction deviating therefrom and respectively have a lateral dimension 1 greater than 2 μm.
