The use of an amine salt of trifluoromethanesulfonic acid as a catalyst for the curing of hydroxyl-functional polymers provides a wrinkle finish. The hydroxy-function may be present in polyesters, epoxies, and acrylate or methacrylate polymers, among others. The polyesters which are able to provide such a finish have a hot plate melt flow of at least about 50 mm but if it is more than 150 mm, the gel time of the polymer must not be more than about 280 seconds. The minimum gel time in the case of polyesters is about 30 seconds.
