ABSTRACT:
The present invention relates to an epoxy ester coating copolymer resin which is useful in the preparation of an air curable, high solids coating, which resin is the reaction product of components (I), (II) and (III); wherein (I) is a polymerizable base of (a) a fatty acid having free radical polymerizable double bonds and (b) a vinyl monomer selected from the group consisting of styrenes, vinyl toluene and mixtures thereof; (II) is an epoxy resin and (III) is a monobasic acid. The epoxy ester copolymer resin of the invention is prepared by the reaction of (I), (II) and (III) at an elevated temperature to an acid number below 10.
