ABSTRACT:
Disclosed are a phthalocyanine composition having main diffraction peaks at 7.5.degree., 22.5.degree., 24.3.degree., 25.3.degree. and 28.6.degree. of Bragg angles (2.theta..+-.0.2.degree.) in an X-ray powder diffraction spectrum with Cu K.alpha. radiation, a process for preparing the same, an electrophotographic photoreceptor using the same and a coating solution for a charge generation layer containing the same. The composition is made from a mixture of a titanylphthalocyanine and a halogenated group IIIA metal phthalocyanine which has been made amorphous by a strong mineral acid and crystallized from an organic solvent.
