Abstract
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.
