Abstract
The present invention relates to multilayer pigments based on glass flakes and to a method for the production of such pigments. The resulting pigment can be used in any application for which pearlescent pigments have been heretofore used such as, for example, in plastics, paints, inks, cosmetic formulations, coatings including solvent or waterborne automotive paint systems, powder coatings, inks and agriculture foils, for the laser-marking of papers and plastics.
