The present invention provides imide-containing and amide-containing polyester resins which are useful in the formulation of coating compositions and inks. 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.

Modified polyesters

Disclosed are compositions of matter comprising the reaction products of polyesters and 2,2-dimethyl-3-hydroxypropyl-2,2-dimethyl-3-hydroxypropionate, the reaction products containing, by weight, about 40-80% of a polyester and about 60-20% of 2,2-dimethyl-3-hydroxypropyl-2,2-dimethyl- 3-hydroxypropionate and having a hydroxyl number of about 150-300. The compositions are especially useful in high-solids coatings.

Glycolized polyesters

Disclosed are linear, water-dissipatable polyesters and polyesteramides derived from at least one dicarboxylic acid, at least one glycol, and at least one polycarboxylic acid or polyhydric alcohol which contains a sulfonic acid salt moiety derived from a nitrogen-containing base having an ionization constant in water at 25.degree. C. of 10.sup.-3 to 10.sup.-10. The polyesters may also contain an unsaturated acid and a difunctional hydroxycarboxylic acid, an aminocarboxylic acid or a diamine. Such polymers are especially useful as adhesives, coatings, films and the like.
