Abstract
A liquid toner composition for use in electrographic imaging comprises a non-aqueous solvent and a soluble dispersant made from thermodynamically compatible polymers containing functional groups with good adsorption properties for cyan, magenta, yellow and black pigments. The invention also describes the incorporation of reactive functional groups that crosslink on heat treatment to improve modulus and scratch resistance.
