PROCEDURE

实验过程

The present invention provides a process for producing hydroxygallium phthalocyanine crystals, which process comprises reacting a gallium compound with an excess of a compound forming a phthalocyanine ring to prepare gallium phthalocyanine, subjecting the resulting gallium. phthalocyanine to acid pasting to obtain a hydroxygallium phthalocyanine crystal having intense diffraction peaks at Bragg angles (2θ±0.2°) of 6.9°, 13.2° to 14.2°, 16.5°, and 26.4° or of 7.0°, 13.4°, 16.6°, 26.0°, and 26.7° in Cukα characteristic X-ray diffractometry, and transforming the resulting crystal by a solvent treatment into hydroxygallium phthalocyanine crystals having intense diffraction peaks at Bragg angles (2θ±0.2°) of 7.5°, 9.9°, 12.5°, 16.3°, 18.6°, 25.1°, and 28.3° in Cukα characteristic X-ray diffractometry.
