摘要:
A silicone-containing polyester polyol can include a reaction product prepared from reactants including: a diol; a polyol having at least three hydroxyl groups; a dimer of a fatty acid having two carboxylic acid groups, or an anhydride or ester thereof; and a silicone component having siloxane linkages and at least two reactive functional groups selected from hydroxyl groups, amino groups, thiol groups, carboxylic acid groups, anhydride groups, or combinations thereof. A coating composition for preparing an anti-fingerprinting, soft touch coating can include the silicone-containing polyester polyol and a crosslinker reactive with the silicone-containing polyester polyol.
