摘要：
An improved process for preparing oxytitanium phthalocyanine is provided wherein the condensation reaction of o-phthalodinitrile with titanium tetrachloride is effected in an organic solvent at 170.degree. to 300.degree. C. followed by hydrolysis, the improvement wherein said organic solvent is preliminarily heated at a temperature of 160.degree. to 300.degree. C. prior to initiation of the condensation reaction. The A form of oxytitanium phthalocyanine crystal can selectively be produced in the pure state.
