Abstract: A process for the preparation of titanyl phthalocyanine Type X which comprises dissolving titanyl phthalocyanine Type I in a solution of trifluoroacetic acid and methylene chloride; adding the resultant solution to a solvent 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; and thereafter a solvent treatment with fluorobenzene.

Abstract: Disclosed are various titanyl phthalocyanine polymorphs such as Type I, Type II, Type III, Type IV, Type Z-1, Type Z-2, and Type X, which phthalocyanines can be prepared by dissolving a titanyl phthalocyanine in a solution of trifluoroacetic acid and a chlorinated hydrocarbon. There is then added to the resulting solution a solvent that will enable precipitation of the titanyl phthalocyanine. Subsequently, the titanyl phthalocyanine product can be separated from the solution by, for example, filtration and the product titanyl phthalocyanine obtained can be washed to remove any residual solvent.
