Abstract

A curable coating composition contains a polymer having pendant mercaptan groups and a bis-maleimide cross-linking agent. The mercaptan groups of the polymer cross-link with the bis-maleimide upon curing to form a fully cured coating. In a preferred embodiment, the coating composition serves as a cathodic electrocoating composition.
