Patent ID: 7057034

Claim:
A titanyl phthalocyanine crystal formed by crystallizing a titanyl phthalocyanine compound, characterized in that the crystal has a maximum peak at a Bragg angle 2θ±0.2°=27.2°, has no peak at 7.4° in a CuKα characteristic X-ray diffraction spectrum, and the crystal does not have a peak of a change in temperature within the range from 50–400° C. except for a peak associated with evaporation of adsorbed water in differential scanning calorimetry, and the crystal recovered after dipping in an organic solvent for 7 days has a maximum peak at a Bragg angle 2θ±0.2°=27.2° and has no peak at 7.4° in a CuKα characteristic X-ray diffraction spectrum.
