Abstract:
The present invention provides .mu.-oxo-aluminum phthalocyanine dimer having a novel polymorph. The .mu.-oxo-aluminum phthalocyanine dimer may be applied to as a charge generator for an organic photoconductive material, such as a high-gamma photoreceptor which is corresponding to a short-wavelength of light sauce (LED). The .mu.-oxo-aluminum phthalocyanine dimer having a novel polymorph which shows diffraction peaks at a Bragg angle (20.theta..+-.0.2.degree.) of 6.9.degree., 9.7.degree., 13.8.degree., 15.4.degree., 23.9.degree., and 25.9.degree. in a X-ray diffraction spectrum by CuK .alpha.-ray.
