    • 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 1.5; and d) a positive charge director with the acid-base copolymer charge dispersant system and a negative charge director with the base-acid copolymer charge-dispersant system.
