Abstract: The invention relates to resin intermediates and their preparation. The invention also relates to hydroxyl-functional, water-dispersible polymers formed from the intermediates and compositions containing the water-dispersible polymers. A preferred composition of the invention is a zero volatile organic content (VOC), ambient-cure enamel composition which contains a hydroxyl-functional, water-dispersible polyester.
