Abstract
A process for the production of an aluminum phthalocyanine composition or a halogenated aluminum phthalocyanine composition in high yield and purity is provided which entails bringing a molten salt of aluminum chloride and/or aluminum bromide and a phthalocyanine compound having a central element other than aluminum into contact with each other in a predetermined temperature range thereby to substitute aluminum for the central element. Alternatively, the process involves conducting the aforementioned step, and introducing a halogen into the resultant reaction mixture.
