Abstract
Abstract N-Substituted acryloyloxyethyl amines are useful both as radiation curable coating materials and as cure accelerators in coating formulations. The amines are prepared by one of several methods including transesterification of acrylate esters with an N-substituted hydroxyethylamine or acrylation of the N-substituted hydroxyethylamine.
