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.

Curable aqueous dispersions of acrylate-modified polyamide resin

Polyamide resins are produced by reacting diamines, polymeric fatty acids, and monoamines. The monoamine component serves as a chain stopper and renders the polyamide resin product soluble in toluene. The resulting resins are especially useful as binder components in printing inks, and are distinguished by their ready solubility in toluene alone.
