Abstract
Provided are polyester resins containing hydroxy functionalized isophthalate ester moieties useful in coating compositions. The invention provides both solvent-borne as well as water-borne coating compositions comprised of the resins and a crosslinker such as a melamine-type crosslinker. Polyester resins of the present invention having a T.sub.g of greater than about 50.degree. C. are useful in thermosetting powder coating compositions. The coatings thus provided possess excellent acid resistance, hardness, impact resistance, and stain resistance.
