Abstract
Polymer composition particularly useful as protective surface coatings comprise an aqueous mixture of epoxy-acrylic graft copolymers combined with a functional low molecular weight polyester and minor amounts of an amine derivative crosslinking resin. The low molecular weight polyester contains reactive hydroxyl or carboxyl functional groups and a molecular weight less than about 2,000.
