ABSTRACT:
A process is disclosed for preparing resin extended pigments containing from 10% to 75% and preferably 20% to 50% by weight, based on the amount of pigment and resin present. The crude pigment and resin are comilled, such as in a ball mill, in a manner equivalent to that used to prepare pigmentary grade pigment from crude pigment. Liquids if they are present should not affect the free flowing nature of the mill powder. The resin is a polyolefin or a copolymer of ethylene and up to 25% of acrylic acid, methacrylic acid, vinyl acetate, or oxidized ethylene units preferably softening at from 80.degree. to 140.degree. C.
