Claim:
1. A coating composition having at least one of a solids content of greater than 70% by weight and a Volatile Organic Content (VOC) of less than 250 g/l, comprising a polyester polyol, the polyester polyol prepared from reactants comprising: a) from 10 to 40 weight percent of one or more polyols comprising 3 or more hydroxyl groups per molecule, b) from 10 to 40 weight percent of one or more aromatic polycarboxylic acids comprising 2 or more acid groups per molecule or corresponding ester(s) and/or anhydride(s) thereof, and c) from 30 to 75 weight percent of one or a mixture of C wherein the polyester polyol has a hydroxyl value (OHV) of greater than 60 and less than 200 mgKOH/g, and the weight percent of each component (a), (b) or (c) is the percentage of the weight of that component to the total weight of (a)+(b)+(c), and at least one isocyanate-functional curing agent, and wherein the coating composition is capable of curing at ambient temperature.
