Abstract
This invention is directed to thermosetting coating compositions comprising blends of phenol-functional polyesters and hydroxyl-functional acrylic copolymers. The resin blends are formulated with an amino crosslinker to form industrial baking enamels. Coatings thus obtained exhibit improved acid-etch resistance over those based on hydroxyl-functional acrylic resins and have a good combination of hardness and impact resistance. These coatings are particularly useful as automotive coatings.
