A liquid toner composition for use in high viscosity electrostatic printing processes. The liquid toner comprises a non-aqueous carrier liquid which is an electrically non-conductive liquid being a silicone fluid of straight chained or cyclic configuration, a silicone fluid of cyclic configuration, a silicone fluid of branched configuration, or a combination thereof having a viscosity in the range of from 0.5 to 1,000 mPa.s, an insoluble marking particle, and a dispersion additive, the dispersion additive comprising a polysiloxane having at least one functional group comprising a radical which introduces an active site into the polysiloxane and wherein the functional group is a radical selected from the group comprising a vinyl group, a carboxylic group, a hydroxyl group, or an amine group. The particular advantage of the liquid composition is that the formation of rivulets is minimised during printing with resultant improvement in image quality. |
