    摘要: A process for the preparation of a more perfect crystalline form of the Type I polymorph of titanyl phthalocyanine which comprises dissolving a precursor titanyl phthalocyanine Type I in a solution of trihaloacetic acid and alkylene chloride; adding the resultant solution to a solvent thereby enabling precipitation of Type X titanyl phthalocyanine; separating the titanyl phthalocyanine Type X from the solution; followed by a first washing with an organic solvent and a second washing with water; slurrying the resulting Type X titanyl phthalocyanine in an organic solvent enabling conversion of said Type X to Type IV titanyl phthalocyanine; and thereafter, subjecting the Type IV titanyl phthalocyanine obtained to treatment with an organic solvent to enable said crystalline form of titanyl phthalocyanine Type I.

    摘要: A layered photoconductive imaging member comprised of a supporting substrate, a photogenerating layer comprised of titanyl phthalocyanine photogenerating pigments and thereover a charge transport layer, and wherein said photogenerating pigments are prepared by a process which comprises the formation of a slurry comprised of dihalotitanium phthalocyanine in a mixture comprised of a trihaloacetic acid and an alkylene chloride; adding the resultant slurry to a mixture of an aliphatic alcohol and water enabling hydrolysis whereby Type X oxytitanium phthalocyanine is obtained; separating the Type X oxytitanium phthalocyanine from the slurry; and thereafter subjecting the Type X oxytitanium phthalocyanine obtained to treatment with a halobenzene, followed by the separation of Type IV oxytitanium phthalocyanine photogenerating pigments.
