Abstract
Disclosed are polyester resins and solvent borne thermosetting coating compositions that include these resins in combination with at least one crosslinker. The polyester resins contain 2,2,4,4-tetramethyl-1,3-cyclobutanediol and exhibit a combination of good solubility in organic solvents and high hardness with good flexibility in a coating composition.
