Abstract
Aqueous primer compositions suitable for electrophotographic printing and inkjet printing are frequently incompatible with one another, such that coated substrates for each printing technique need to be stockpiled separately. Aqueous primer compositions containing components to facilitate both electrophotographic printing and inkjet printing and that remain compatible with each other may comprise a polyvalent metal salt dispersed in an aqueous fluid, and an amine-functionalized copolymer dispersed as an emulsion in the aqueous fluid, in which the amine-functionalized copolymer has an amine number of about 10 to about 180 mg KOH/g copolymer and a glass transition temperature of about 0° C. to about 50° C. 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.
