ABSTRACT:
A process for preparing a high sensitivity titanyl phthalocyanine (TiOPc) pigment includes dissolving a Type I TiOPc in a suitable solvent, precipitating an intermediate TiOPc pigment by quenching the solution comprising the dissolved Type I TiOPc in a solvent system comprising an alcohol and alkylene chloride such as, for example, methylene chloride, and treating the intermediate TiOPc pigment with monochlorobenzene. The resultant TiOPc pigment, which is designated as a Type V TiOPc, is suitable for use as a charge generating material in a photoreceptor of an imaging device.
