Abstract
Disclosed are thermosetting, powder coating compositions comprised of semi-crystalline polyesters and .epsilon.-caprolactam-blocked bis(1-cyanato-1-methylethyl) benzene compounds which are readily curable at relatively-mild temperatures and using cure times commonly used to cure (cross-link) powder coatings. When using equivalent curing conditions, the disclosed coating compositions exhibit a higher degree of cross-linking than do combinations of amorphous polyesters and the .epsilon.-caprolactam-blocked bis(1-cyanato-1-methylethyl)-benzene compounds.
