Abstract
Essentially linear polyester resins are made with a limited number of reactive hydroxyl and carboxyl groups pendant thereto. Such polyester resins are made water-dispersible by admixing therewith selected coupling solvents and amine compounds. Heat-curable coatings formulations are made therefrom by combining the water-dispersible polyester resins with water-soluble aminoplast resins and water.
