Abstract: A liquid ink for developing electrophotography images comprises: a) a carrier liquid having a Kauri-Butanol number less than 30; b) a grafted co-polymer comprising a (co)polymeric steric stabilizer covalently bonded to a thermoplastic (co)polymeric core that is insoluble in the carrier liquid, wherein the grafted co-polymer is derived from at least a polymerizable organic compound having at least one acid group or at least one acid group; c) a dispersant having, respectively, at least an amine group or at least one acid group to form an acid-base copolymer-dispersant system or a base-acid copolymer-dispersant system, wherein the mole ratio of the amine group to the acid group is between 0.3 and 1.5 in the base-acid copolymer-dispersant system and the mole ratio of the acid group to the base group in the acid-base copolymer dispersant system is between 0.3 and 1.

Abstract: This invention relates to a liquid ink for developing electrophotographic images comprising: a) a carrier liquid having a Kauri-Butanol number less than 30; b) a plastisol; c) a dispersant; and d) a charge director wherein: a. for a positive charge director, the dispersant has amine groups and the plastisol comprises polymeric particles having acid groups and an acid value between 30 and 150 mg KOH/g such that the mole ratio of the amine groups to the acid groups is between 0.075 and 0.3; and b. for a negative charge director, the plastisol comprises a polymer having an amine value between 5 and 200 mg KOH/g and the dispersant has acid groups such that the mole ratio of the acid groups to the amine groups is between 0.075 and 0.3.
