ABSTRACT:
A compound containing an epoxy group, is reacted with a carboxyl compound by heating a mixture of these compounds in the presence of a benzotriazole such as unsubstituted benzotriazole or tolyltriazole as accelerator. The accelerator is particularly effective in the reaction of a carboxyl compound which is a polyester containing free carboxylic acid groups with an epoxy compound which is triglycidyl cyanurate or an epoxy resin based on bisphenol A.
