Abstract

Mixed pigments containing an organic pigment component and an inorganic pigment component imparting improved gloss and other desirable properties to organic coatings containing the same in relatively large amounts are prepared by synthesizing the organic component in the presence of the inorganic component in a liquid medium inert to the inorganic component, such as nickel titanium yellow or chromium titanium yellow.
