ABSTRACT:
Easily water-dispersed formulations of a phthalocyanine pigment which contain--based on the formulation--(a) from 70 to 95% by weight of finely divided phthalocyanine pigment of which the mean primary particle size is less than 0.5 .mu.m, and (b) from 30 to 5% by weight of one or more alkylarylsulfonic acids, where alkyl is of 4 to 20 carbon atoms, but the sum of the alkyl carbon atoms is not less than 8, which alkylarylsulfonic acids may be in the form of water-soluble salts. A fine dispersion of the formulations is obtainable by sprinkling the formulations into water and shaking. The dispersions obtained are stable and can be filtered through a paper filter without leaving a residue. The finely dispersed pigment is absorbed quantitatively on wool, cotton or paper pulp.
