| titleOfInvention | Crystalline form of a titanyl phthalocyanine obtained by treatment of Type X polymorphic form with substituted aromatic hydrocarbon(s) |
| abstract | There is disclosed a crystalline form of a titanyl phthalocyanine characterised by having an XRD pattern showing a maximum peak at a Bragg angle (20Œ0.2‹) of about 27.3‹ and further diffraction peaks in decreasing order of intensity at Bragg angles (20Œ0.2‹) of about 9.0‹, about 9.5‹, about 24.1‹ and about 14.3‹. Its use in charge generating materials, photoconductive members and electroreprographic devices is also disclosed. A process for its preparation comprises the following steps: a) reacting an optionally substituted phthalonitrile with ammonia in the presence of alkali metal alkoxide (eg sodium or potassium methoxide) to form a diiminoisoindoline; b) reacting the diiminoisoindoline obtained from step 'a)' with titanium tetraalkoxide (eg the tetrabutoxide) to form a titanyl phthalocyanine of the polymorphic crystal form known as Type I; c) dissolving the Type I titanyl phthalocyanine obtained from step 'b)' in a mixture of alkane sulphonic acid (eg methanesulphonic acid) and halogenated aliphatic hydrocarbon (eg dichloromethane) to form a titanyl phthalocyanine of the polymorphic crystal form known as Type X; and d) treating the Type X titanyl phthalocyanine obtained form step 'c)' with substituted aromatic hydrocarbon (eg methoxybenzene) until a titanyl phthalocyanine is formed having the XRD pattern stated above and then collecting the titanyl phthalocyanine from the substituted aromatic hydrocarbon. |
