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:
wherein
Z is a radical independently selected from C, to C20 alkyl, C3 to C20 cycloalkyl, C6 to C18 aryl, halogen, alkoxy, hydroxyl, and aryloxy;
R is independently selected from hydrogen, C, to C20 alkyl, C3 to C20 cycloalkyl, and C6 to C18 aryl;
R' is independently selected from C, to C20 alkyl, C3 to C20 cycloalkyl, hydroxyalkyl, and hydroxycycloalkyl;
y is an integer from 0 to 4,
w is an integer from 0 to 2, and
x is an integer from 1 to 3.

其中
Z 是独立选自 C 至 C20 烷基、C3 至 C20 环烷基、C6 至 C18 芳基、卤素、烷氧基、羟基和芳氧基的自由基;
R 独立选自氢、C-C20 烷基、C3-C20 环烷基和 C6-C18 芳基;
R' 独立选自 C 至 C20 烷基、C3 至 C20 环烷基、羟基烷基和羟基环烷基;
y 是 0 至 4 的整数、
w 是 0 至 2 的整数,和
