Abstract
A stain resistant coating composition can include: (a) a polyester polyol; (b) a silicone component having at least one reactive functional group; and (c) a crosslinker reactive with (a) and (b). The polyester polyol can include a reaction product obtained from a mixture of reactants including: an aliphatic diol; a polyol having 3 or more hydroxyl groups; and an aliphatic cyclic polycarboxylic acid, or an anhydride or ester thereof, that is greater than 10 mole % of the total carboxylic acids, or anhydrides or esters thereof, used to prepare the polyester.
