ABSTRACT:
Curable coating compositions are provided containing an amine group containing polyepoxide resin, an acetoacetate containing polyester having a weight average molecular weight of at least 1000, and a polyacrylate containing material. The amine group containing polyepoxide can be modified with a ketone and/or an aldehyde to form a ketimine and/or an aldimine containing polyepoxide. The compositions are useful as coatings, particularly as ambient or low temperature curable automotive refinish primer coatings having good corrosion resistance, adhesion to both substrate and other organic coatings, sandability and pot-life.
