Hydroxyl-containing polymers prepared by reaction of a polymerizable alpha, beta-ethylenically unsaturated carboxylic acid and an epoxy compound containing greater than 5 carbon atoms are disclosed. The polymer is prepared by free radical organic solution polymerization techniques. Synthesis of the polymers by this tech- nique assures multiple hydroxyl functionality in all polymer chains thereby providing good cure response. The polymers are useful as binders in high solids coating compositions. When used with appropri- ate curing agents, the resultant coatings have good hardness, high gloss and distinctness of image, have good solvent and humidity resistance and are very resistant to acid etching.
