Abstract

Copper phthalocyanine is produced in a non-crystallizing, non-flocculating form by adding it to a melt of aluminium chloride, with or without sodium chloride, heating the mixture to 140-180 DEG C in absence of further halogenating agents, and recovering the copper phthalocyanine. The product may be pasted with sulphuric acid in the usual way. An example is given.
