ABSTRACT:
Curable compositions with improved humidity resistance are composed of an active hydrogen-containing resin which is essentially free of glycidyl groups, a curing agent present externally and/or internally as a part of the active hydrogen-containing resin, and a catalytic amount of a sulfonic acid having a molecular weight of less than 500 and represented by the following structural formula: ##STR1## wherein: Z is a radical independently selected from C.sub.1 to C.sub.20 alkyl, C.sub.3 to C.sub.20 cycloalkyl, C.sub.6 to C.sub.18 aryl, halogen, alkoxy, and aryloxy;
