Abstract
Electrophotographic printing techniques offer excellent image quality, but image adhesion to a desired substrate may be problematic in many instances. Primer coatings for improving image adhesion to a substrate may be formed from primer compositions comprising a fluid and an amine-functionalized copolymer dispersed in the fluid as an emulsion, in which the amine-functionalized copolymer has an amine number of about 10 to about 180 mg KOH/g copolymer. The fluid may be aqueous or organic. Suitable amine-functionalized copolymers may be formed by an emulsion polymerization reaction of one or more first ethylenically unsaturated monomers lacking an amine group and one or more second ethylenically unsaturated monomers bearing at least one amine group. The at least one amine group comprises a side chain of the amine-functionalized copolymer.
