Abstract

1348571 Copper phthalocyanine pigments KEMISK VAERK KOGE AS 19 April 1971 [20 March 1970] 25164/71 Heading C4P Copper phthalocyanine pigments are produced by mixing a copper phthalocyanine compound, which has previously not at all or not to a satisfactory degree been converted to pigment form, with one or more colour-shading pigments and converting the copper phthalocyanine into pigment in the presence of the shading pigment. The conversion may be carried out by mixing the colour shading pigment and copper phthalocyanine in sulphuric acid to a plastically workable mass, pouring the mass into water, filtering, washing and drying. Alternatively the phthalocyanine may be treated in a kneading machine in the presence of a highly viscous medium, e.g. ethylene glycol. The conversion may also be achieved by grinding the two compounds in a ball mill or attritor, optionally in the presence of salt or other aids. Specified colour shading pigments are carbazol-dioxazine violet, dimethylquinacridon, isoindolines, indolizindione, azo compounds and thioindigo compounds.
