1. An emulsion polymer comprising:
- (a) a support resin emulsion polymerized with (b) at least one ethylenically unsaturated monomer, said support resin being an aqueous polymeric dispersion comprising (i) a substantially non-gelled polymeric composition comprising the reaction product of an A polymer which is an addition polymer having 3.5 or more reactive functional groups per polymer chain and a B polymer having about 2 to about 3 functional groups per polymer chain that are co-reactive with said reactive functional groups of the A polymer;
(i) water; and
(iii) optionally a solubilizing agent.

Abstract
An aqueous polymeric dispersion is described containing at least one substantially non-gelled polymeric composition comprising the reaction product of an A polymer which is an addition polymer having 3.5 or more reactive functional groups per polymer chain and a B polymer having about 2 to about 3 functional groups per polymer chain that are co-reactive with the reactive functional groups of the A polymer and an aqueous solvent. The aqueous polymeric dispersion is particularly useful in or as overprint varnishes, inks, pigment dispersions, paints, adhesives, coatings, support resins, emulsion polymers and the like.
