Abstract
Radiation curable compounds are disclosed comprising an amide moiety, a urethane moiety and an ethylenically unsaturated functional group, typically an acrylate functional group. This class of amide urethane acrylate compounds is characterized in having an amide moiety formed by the condensation reaction between a compound containing one or more carboxylic acid groups and an isocyanato-containing compound. Coating compositions containing one or more of these amide urethane acrylate compounds radiation polymerize at relatively high rates to provide protective and decorative films having improved wear resistance and flexibility.
