Abstract
A process for preparing a tris-lactam crosslinking agent, tris-pyrrolidonyl triazine, from N,N',N'-tris(4-chlorobutyryl)melamine by treatment of the chlorobutyryl derivative with a base such as sodium or potassium carbonate to effect intramolecular cyclization to the tris-lactam. A curable composition comprised of tris-pyrrolidonyl triazine as the crosslinking agent and a hydroxyfunctional or aminofunctinoal material as a resin. Thick films with no pinholes are prepared from the curable compositions using powder coating techniques.
