Abstract

A latex product composition that includes an anionicaily-stabilized latex; at least one volatile base compound; 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 polymers or polymeric adducts are formed by the addition reaction of the amine compound and the one or more epoxy compounds with 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 anionicaily-stabilized latex.
