Abstract
A process for the preparation of hydroxygallium phthalocyanine which comprises hydrolysis of halogallium phthalocyanine precursor to a hydroxygallium phthalocyanine, and conversion of said resulting hydroxygallium phthalocyanine to Type V hydroxygallium phthalocyanine by contacting said resulting hydroxygallium phthalocyanine with an organic solvent; and wherein said precursor halogallium phthalocyanine is obtained by the reaction of gallium halide with diiminoisoindolene in an organic solvent.
