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.

(Meth)acrylated, highly ethoxylated, aromatic polyesters

Floor coverings include a wear layer made from a coat composition including a multifunctional polyurethane (meth)acrylate oligomer. The multifunctional polyurethane is made by reacting a polyisocyanate with a functionality equal or higher than 3, a polyester polyol, and a hydroxyalkyl(meth)acrylate with a number average molecular weight of about 344 to about 472. The coating composition preferably includes a reactive (meth)acrylate diluent and a photoinitiator.

Floor coverings include a wear layer made from a coat composition including a multifunctional polyurethane (meth)acrylate oligomer. The multifunctional polyurethane is made by reacting a polyisocyanate with a functionality equal or higher than 3, a polyester polyol, and a hydroxyalkyl-(meth)acrylate with a number average molecular weight of about 344 to about 472. The coating composition preferably includes a reactive (meth)acrylate diluent and a photoinitiator.

A UV sensitive coating composition is described which is a polymer prepared from a condensation reaction of a diisocyanate, a hydroxy alkyl (di or tri) (meth)acrylate and a carboxylic acid polyol. Optionally, a polyol and/or a dicarboxylic acid polyol can also be included as reactants. The coating polymer, thus prepared, can also be combined with binders and crosslinkers.

A UV sensitive coating composition is described which uses a polymer prepared from a condensation reaction of a diisocyanate, a hydroxy alkyl (di or tri) (meth)acrylate and a carboxylic acid polyol. Optionally, a polyol and/or a dicarboxylic acid polyol can also be included as reactants. The coating polymer, thus prepared, is combined with binders and crosslinkers to form a solder mask.
