The resins comprise the reaction product of an imide or amide, a polyester-forming polyol. a polyester-forming multifunctional acid or derivative thereof, and, optionally, a fatty oil or an unsaturated fatty acid derived from a fatty oil. The imide or amide is derived from a specified alkanolamine and an imide-forming or amide-forming reactant. The alkanolamine is a primary branched alkanolamine wherein the branched alkyl group preferably contains about 2 to 10 carbon atoms. A preferred alkanolamine is 2,2-dimethyl-3-amino-1-propanol.
