Abstract:

PCT No. PCT/DE96/00207 Sec. 371 Date Jul. 15, 1997 Sec. 102(e) Date Jul. 15, 1997 PCT Filed Feb. 2, 1996 PCT Pub. No. WO96/24638 PCT Pub. Date Aug. 15, 1996A process is for producing electrophotographically active titanylphthalocyanine. In the process, which has an improved space-time yield, titanylphthalocyanine is dissolved in pentafluoropropionic acid and a solvent of the group comprising halogenated alkanes/aromatic compounds or halogenated alkanes/aromatic compounds and sulphonic acids. The active form is precipitated by precipitation with water in the presence of a further polar organic solvent. A mixture of pentafluoropropionic acid and methylene chloride and a mixture of p-toluene sulphonic acid and methane sulphonic acid are particularly suitable as solvents. The precipitated product processes very good electrophotographic properties.
