ABSTRACT:
A process for the preparation of hydroxygallium phthalocyanine and elements containing same which comprises the synthesis of a precursor halogallium phthalocyanine by the reaction of a diiminoisoindolene with gallium acetylacetonate; hydrolysis thereof to hydroxygallium phthalocyanine; and conversion of the resulting hydroxygallium phthalocyanine obtained to Type V hydroxygallium phthalocyanine by contacting said resulting hydroxygallium phthalocyanine with an organic solvent.
