摘要:
The invention relates to a liquid developer composition comprising a dispersant, and toner particles dispersed in said dispersant. The liquid developer composition can be used for printing onto a substrate. The binder resin in the toner particles is curable, e.g. by UV-light.

摘要:
A 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.
