Abstract
Herein is described a liquid electrophotographic ink composition including a carrier liquid and a resin including an acid copolymer and an acrylate copolymer, wherein the acrylate copolymer includes at least about 30 wt. % of the alkyl (meth)acrylate monomer.
Claims15
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;
- and
- at least about 0.1 wt. % by total weight of the resin of an acrylate copolymer of an alkylene monomer and an alkyl (meth)acrylate monomer, the acrylate copolymer comprising at least about 30 wt. % of the alkyl (meth)acrylate monomer.

A method of producing a liquid electrophotographic ink composition, the method comprising combining a carrier liquid and a resin to form a mixture, the resin comprising:
- an acid copolymer of an alkylene monomer and a monomer having an acid side group;
- and
- at least about 0.1 wt. % by total weight of the resin of an acrylate copolymer of an alkylene monomer and an alkyl (meth)acrylate monomer, the acrylate copolymer comprising at least about 30 wt. % of the alkyl (meth)acrylate monomer.
A printed substrate comprising:
- a print substrate;
- and
- a liquid electrophotographically printed image layer comprising a resin comprising:
- an acid copolymer of an alkylene monomer and a monomer having an acid side group;
- and
- at least about 0.1 wt. % by total weight of the resin of an acrylate copolymer of an alkylene monomer and an alkyl (meth)acrylate monomer, the acrylate copolymer comprising at least about 30 wt. % of the alkyl (meth)acrlate monomer.
