Abstract
The particle size of quinacridone pigments and phthalocyanine pigments containing statistically not more than one substituent per molecule is reduced by dry-milling the pigment in apparatus having attrition and shearing action, effecting contact between the dry-milled pigment obtained and a water emulsion of an organic liquid which is an aliphatic, halogenated aliphatic or saturated cycloaliphatic hydrocarbon boiling between 35 DEG C. and 85 DEG C., the amount of organic liquid used being at least 0.1 part by weight per part of pigment and thereafter removing the organic liquid and recovering the pigment. Specified quinacridone pigments are 4,11-dichloroquinacridone, 2,9 - dichloroquinacridone, 2,9 - dimethylquinacridone, 4,11 - difluoroquinacridone and 2,9-dimethoxyquinacridone. Specified phthalocyanine pigments are metal-free phthalocyanine, Cu-phthalocyanine, phthalocyanines of the metals Ni, Co, Fe, Mg, Pb and V; and Cuphthalocyanine containing a small amount of chlorine. Specified organic liquids are CCl4, CHCl3, CH2Cl2, C6H14, cyclohexane an fluorinated hydrocarbons. Examples of the above process are given.ALSO:The particle size of quinacridone pigments and phthalocyanine pigments containing statistically not more than one substituent per molecule is reduced by dry-milling the pigment in apparatus having attrition and shearing action, effecting contact between the dry milled pigment obtained and a water emulsion of an organic liquid which is an aliphatic halogenated aliphatic or saturated cycloaliphatic hydrocarbon boiling between 35 DEG C and 85 DEG C, the amount of organic liquid used being at least 0.1 part by weight per part of pigment, and thereafter removing the organic liquid and recovering the pigment.
