Abstract: A stain resistant coating composition includes: urethane acrylate core-shell particles including (1) a polymeric acrylic core; and (2) a polymeric shell including a urethane linkage. The polymeric shell is formed from a reaction mixture including an isocyanate and a polyol. The polyol is substantially free of a six or more consecutive methylene group chain and/or the polyol is formed from monomers comprising a monomer content including at least 10 wt % substituted polyol and/or substituted polyacid and/or at least 25 wt % polyol or polyacid containing cyclic content, based on the total weight of the monomers forming the polyol.

Abstract: 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.
