Abstract
Aqueous dispersions of acrylate-modified polyamide resin having unreacted acrylate functionality are provided. These acrylate-modified polyamide dispersions cure upon exposure to either ultraviolet radiation or thermal energy to form cross-linked films useful, for example, as adhesive coatings. In a preferred embodiment, acrylate-modified dispersions are formed by the addition of a polyol ester having a multiplicity of acrylate ester groups to a polyamide resin having a multiplicity of free amino groups under conditions effective to form the Michael addition product thereof.
