A coating composition which exhibits excellent sag resistance without the necessity for externally added rheology control agent is prepared from a curing agent and an ungelled hydroxyl functional graft copolymer. The graft copolymer is prepared by the vinyl addition polymerization, in an inert organic solvent, of a vinyl monomer component containing at least a portion of a carboxyl functional vinyl monomer in the presence of a glycidyl ester containing acrylic polymer. The grafting occurs by the condensation reaction between the carboxyl groups of the vinyl monomer component and the epoxy groups of the glycidyl ester containing acrylic polymer.
