ABSTRACT:
The present invention relates to platelet-shaped pigments comprising (a) a layer obtained by calcination of a layer comprising SiOzwherein 0.03≦z≦2.0 and a metal, to a process for the production thereof, and to the use thereof in paints, text ink-jet printing, cosmetics, coating compositions, plastics, printing inks and in glazes for ceramics and glass. The aforementioned process makes available platelet-shaped pigments having a high degree of planeparallelism and a defined thickness in the range of ±10%, preferably ±5%, of the average thickness.
