Procedure

An aliquot (400 parts) of the α-copper phthalocyanine pigment (C-2) obtained in Production Example 11(2) and containing copper monomethylphthalocyanine, common salt (1,600 parts) and diethylene glycol (400 parts) were milled for 6 hours in a kneader while controlling the temperature of the contents at 80 to 100° C. The resulting contents were subjected to treatment with a dilute acid and then to filtration. The thus-collected solids were washed with water, and then dried to obtain a fine β-copper phthalocyanine pigment (C-4) containing copper monomethylphthalocyanine.
