Abstract
Disclosed herein is a liquid electrophotographic ink composition comprising a first resin comprising a copolymer of an alkylene monomer and a methacrylic acid monomer; a second resin comprising a copolymer of an alkylene monomer and from about 5 wt. % to about 11 wt. % of an acrylic acid monomer; and a colorant in an amount of at least 20 wt. % of the solids of the electrophotographic ink composition. Also disclosed herein is a method of producing a printed substrate from the liquid electrophotographic ink composition.
