Abstract
This invention relates to a titanium dioxide coated mica platey pigment which displays high luster or reflectivity in a suitable coating on a smooth surface, and which has a high resistance to change in appearance when subjected to weatherability stress. The titanium dioxide must be in the rutile crystal structure, the calcining of the titanium dioxide coated mica product must be carried out under rather extended time-temperature conditions, and the product requires a post-treatment with chromium III hydroxide.
