Abstract
A resin composition comprises an acrylated polyester, the polyester being the reaction product of an equivalent excess of 1,6-hexanediol and an aromatic polycarboxylic acid or anhydride, preferably trimellitic anhydride. In the preferred embodiment, the reaction product includes a highly ethoxylated triacrylate. Upon UV initiated polymerization or copolymerization, improved clear coatings for "no-wax" resilient floors are obtained. These coatings have better resistance to household and other stains than commercial urethane/acrylate floor coverings.
