ABSTRACT:
The use of cyclamic acid as a catalyst for the curing of hydroxyl-functional resins having a functionality greater than 2 provides a wrinkle finish. The hydroxy-function may be present in polyesters, epoxies, and acrylate or methacrylate resins, among others. The polyester resins which are able to provide such a finish have a hot plate melt flow of from about 20 mm to about 150 mm.
