ABSTRACT:
A novel C-centered monoclinic bromoindium phthalocyanine pigment is obtained by reacting high-purity diiminoisoindoline with indium tribromide in the solvent, 1-methyl-2-pyrrolidinone. Multiactive photoconductive elements prepared by dispersion-coating a charge-generation layer containing this pigment have high sensitivity to near-infrared radiation.
