The present invention relates to platelet-shaped pigments that comprise a layer obtained by calcining TiO.sub.2/SiO.sub.y or TiO.sub.2/metal, especially TiO.sub.2/AI (0.03.ltoreq.y.ltoreq.1.95, especially 0.03.ltoreq.y.ltoreq.1.8, more especially 0.70.ltoreq.y.ltoreq.1.8), and to the use thereof in paints, textiles, ink-jet printing, cosmetics, coatings, plastics, printing inks, in glazes for ceramics and glass, and in security printing. The pigments according to the invention are distinguished by a high gloss and a very uniform thickness, as a result of which very high color purity and color strength are obtained.
