Abstract

Copper polybromochlorophthalocyanines are made by treating copper phthalocyanine or an incompletely halogenated derivative thereof in a melt of aluminium chloride and an alkali metal chloride with chlorine and at least 10 atomic proportions of bromine per mole of copper phthalocyanine, the bromine treatment being carried out either before or simultaneously with the treatment with chlorine and the process being continued until a copper polybromochlorophthalocyanine containing at least 15 atoms of halogen per molecule is produced. Examples are given. Specifications 719,072 and 925,266 are referred to.
