LIQUID ELECTROPHOTOGRAPHIC INK COMPOSITIONS

摘要

Described herein is a liquid electrophotographic ink composition comprising: a thermoplastic resin comprising a polymer having acidic side groups; a charge adjuvant comprising a complex of a metal(II) cation and two monovalent anions; or a complex of a metal(III) cation and three monovalent anions; or a complex of a metal(III) cation, a monovalent anion and a divalent anion, wherein each monovalent anion is independently selected from carboxylate anions having from 2 to 16 carbon atoms and alkoxide anions having from 1 to 16 carbon atoms; and wherein the divalent anion is selected form the oxo group, dicarboxylate anions having from 2 to 16 carbon atoms, and dialkoxide anions having from 1 to 16 carbon atoms; and a liquid carrier. Also described herein is a method of producing the liquid electrophotographic ink composition and a printed substrate.
