Aminoplast curable coating compositions containing polycyclic esters of sulfonic acids as latent acid catalysts

摘要

A high solids, organic solvent based, sprayable coating composition which is capable of acid catalyzed crosslinking is composed of an active hydrogen-containing resin, a curing agent present externally and/or internally as a part of the active hydrogen-containing resin, and a catalytic amount of a non-ionic, saturated or unsaturated organic polycyclic ester of a sulfonic acid.
