ABSTRACT:
Radiation curable compounds are disclosed comprising an amide moiety, a urethane moiety and an ethylenically unsaturated functional group, typically an acrylate functional group. The compounds comprise the reaction products of an amide-containing compound having at least one hydroxy functional group, a polyisocyanate and a polyfunctional compound having a hydroxy functional group reactive with an isocyanato group of the polyisocyanate, which polyfunctional compound provides an ethylenic functional group in the reaction product. Coating compositions containing these radiation curable reaction products cure at relatively high rates to form films having high abrasion resistance and improved tensile strength and elongation properties as compared to conventional urethane acrylate coating compositions.
