Abstract

Copper phthalocyanine is purified by (a) treating with a hot detergent solution, e.g. a 2% solution of alkyl aryl sulphonates at 98 DEG to 100 DEG C., (b) filtering the mass and then washing the mass with dilute sulphuric acid, e.g. 5% strength. Preferably, the detergent solution to pigment weight ratio is 4 to 1.
