"NACREOUS PIGMENTS, THEIR PREPARATION, AND THEIR USE" ABSTRACT OF THE DISCLOSURE Nacreous pigments comprise a mica platelet coated with a first layer of a metal oxide and a second layer of chromium(III) oxide, wherein the chromium oxide layer further contains at least 0.05 mol % of phosphate ion based on the number of moles of chromium ion therein. Because of the phosphate ion, the chromium layer is con- tinuous and essentially crack-free even at larger thick- nesses, and contributes to the interference effect. The pigments are particularly useful as lustrous agents in cosmetics.
