Resinated 2,9-dimethylquinacridone

摘要: This invention relates to a resinated 2,9-dimethylquinacridone pigment, which is prepared by process comprising (a) preparing an aqueous suspension containing mixture of water-soluble acid salts and particle growth inhibitor, wherein the consists essentially from about 50 95 parts weight resin salt, 5 salt napthenic or dimeric acid, thereof, (b) precipitating in form insoluble (c) isolating 2,9-dimethylquinacfidone pigment suspension. The possesses excellent dispersability, color strength, saturation heat stability. It especially useful for coloring plastics, coatings inks.
