Titanyl phthalocyanine crystal and production method of the same, and electrophotosensitive material |
摘要 |
The present invention relates to a novel titanyl phthalocyanine crystal which can prepare a coating solution having excellent storage stability because it satisfies both of the following two characteristics (a) and (b), a method of producing the same, an electrophotosensitive material using the above crystal as an electric charge generating material. (a) The crystal has a maximum peak at a Bragg angle 2theta±0.2°=27.2° and has no peak at 7.4° in a CuKalpha characteristic X-ray diffraction spectrum. (b) The crystal does not have a peak of a change in temperature within a range from 50 to 400° C. except for a peak associated with evaporation of adsorbed water in differential scanning calorimetry.
