Abstract: The present teachings describe a process for converting a HOGaPc Type I polymorph to the HOGaPc Type V polymorph. The process includes obtaining a slurry comprising hydroxy gallium phthalocyanine (HOGaPc) Type I polymorph. The slurry is mixed at a resonant frequency of the slurry by applying a low frequency acoustic field for a time sufficient to convert the HOGaPc Type I polymorph to the HOGaPc Type V polymorph.

Abstract: Processes for making organic pigments useful in imaging members, specifically for pigments that after further polymorphic conversion may be used in a charge generating layer of an imaging member. More specifically, there are described processes for producing titanyl phthalocyanine (TiOPc) in high yields using tetrahydronaphthalene as reaction solvent, such as TiOPc Type I. This pigment can be successfully converted to a high sensitivity crystal form useful as charge generating pigment in an imaging member.
