Abstract
A curable coating composition is described comprising a carbamate functional material and a crosslinking agent, reactive with the carbamate group. The composition further comprises a third component that is a mixture of catalysts including a phosphorus containing acid or acid derivative and other acid catalysts. Coatings prepared with this coating composition can be cured and coated with additional coating(s), providing good intercoat adhesion to the subsequent coating.
