Abstract: An anionically-stabilized aqueous emulsion composition includes a) a first emulsion polymer having a Tg from −60° C. to 40° C.; b) a volatile base; and c) polymeric particles, different from the first emulsion polymer and present in emulsified form. The c) polymeric particles are polyamine graft copolymers, in which vinyl monomers form a polymer grafted to a water-soluble amino-group containing polymer. The anionically-stabilized aqueous emulsion composition may have a pH of from 8 to 11.

Abstract: A latex product composition that includes an anionically-stabilized latex and one or more water soluble, polymers or polymeric adducts that have a backbone with a plurality of amine functional groups and hydroxyl functional groups. The polymers or polymeric adducts may be an addition product formed from at least one multifunctional amine compound reacted with one or more polyfunctional epoxy compounds, one or more monofunctional epoxy compounds, or a combination thereof. The amine compound and the one or more epoxy compounds are reacted to form polymers or polymeric adducts with the molar equivalent ratio of 1.3 to 3.8 amine functional group per epoxy functional group. The addition product may be present in about 0.1 to 15.0 wt. % and the at least one volatile base compound is present in about 1.0 wt. % to 10.0 wt. % based on the weight of the particles present in the anionically-stabilized latex.
