Brilliant goniochromatic pigments based on iron oxide platelets bearing multiple coatings

摘要

Goniochromatic lustrous pigments based on multilayer iron oxide platelets contain a layer packet comprising (A) a colorless layer of refractive index (RI) n = 1.8 or below; and (B) a colorless layer with n = 2.0 or above. An Independent claim is also included for the production of the lustrous pigments comprising depositing layers (A) and (B) on Fe oxide platelets by either hydrolytic or gas phase decomposition of an (in)organic compound.
