A process for conditioning organic pigments by milling or kneading said pigments in the presence of 0.05 to 25% by weight, based on the pigment to be milled, of at least one micronized wax. The process, in which the use of organic solvents may be dispensed with, yields in a single milling operation,

A process for conditioning organic pigments by milling or kneading said pigments in the presence of 0.05 to 25% by weight, based on the pigment to be milled, of at least one micronized wax. The process, in which the use of organic solvents may be dispensed with, yields in a single milling operation, pigments which are distinguished by excellent dispersibility and outstanding fastness properties.
