ABSTRACT:
Pigment compositions including nickel titanium yellow or chromium titanium yellow as an inorganic component together with an organic pigment component impart better gloss and/or hiding power to organic coatings containing 10% or more of the compositions if the compositions are prepared by subjecting a suspension of the components in a liquid medium to intense shearing stresses and thereafter separating the mixed pigments from the medium.
