Abstract
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 ester of a sulfonic acid. The sulfonic acid ester is represented by the following structural formulas: ##STR1## wherein: Z is a radical selected from the group consisting of amino and an organic radical, said organic radical being connected to the sulfur atom by a carbon atom; PA1 W is C.sub.1 -C.sub.18 alkylene, C.sub.2 -C.sub.18 alkenylene; PA1 V is C.sub.1 -C.sub.18 alkylene, C.sub.1 -C.sub.18 hydroxyl substituted alkylene, C.sub.2 -C.sub.18 alkenylene, C.sub.2 -C.sub.18 hydroxyl substituted alkenylene; and PA1 R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 are independently hydrogen or an organic radical.
