1. A liquid electrophotographic ink composition comprising:
a carrier liquid; and
a resin comprising:
an acid copolymer of an alkylene monomer and a monomer having an acid side group, wherein the acid copolymer is absent of ester groups; and
at least about 0.1 wt. % by total weight of the resin being an acrylate copolymer of an alkylene monomer and an alkyl (meth)acrylate monomer, the acrylate copolymer consisting of 35 wt. % to 50 wt. % of the alkyl (meth)acrylate monomer, with a remaining component of the acrylate copolymer consisting of the alkylene monomer.
