Abstract
Curable coating compositions based on polyepoxide-containing polymers and polyacid curing agents are disclosed. The polyepoxide-containing polymers contain one or more pendant groups of carbamate, urea or urethane groups. The coating compositions are useful as clear coats in composite color plus clear coatings where the pendant groups provide for intercoat adhesion.
