    摘要： An improved curable composition capable of acid catalyzed crosslinking is composed of an active hydrogen-containing resin, a curing agent and a sulfonate as latent acid catalyst. The catalyst is 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, hydroxyl, and aryloxy;R is independently selected from hydrogen, C.sub.1 to C.sub.20 alkyl, C.sub.3 to C.sub.20 cycloalkyl, and C.sub.6 to C.sub.18 aryl;R.sup.1 is independently selected from C.sub.1 to C.sub.20 alkyl, C.sub.3 to C.sub.20 cycloalkyl, hydroxyalkyl, and hydroxycycloalkyl;y is an integer from 0 to 4,w is an integer from 0 to 2, andx is an integer from 1 to 3, with the proviso that when w is 0, y is an integer from 1 to 4 and x is an integer from 2 to 3 and when y is 0, w is an integer from 1 to 2 and x is an integer from 1 to 3.

    摘要： 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;R is independently selected from hydrogen, C.sub.1 to C.sub.20 alkyl, C.sub.3 to C.sub.20 cycloalkyl and C.sub.6 to C.sub.18 aryl;y is an integer from 0 to 4; w is an integer from 0 to 2;x is an integer from 1 to 3, with the proviso that when w is 0, y is an integer from 1 to 4 and x is an integer from 2 to 3 and when y is 0, w is an integer from 1 to 2 and x is an integer from 1 to 2.
