Abstract
Abstract A decorative product constructed of polymeric materials is provided wherein the top layer of the product is a film or layer of thermoplastic polymer (e.g., polyvinyl chloride) having a relief pattern on one surface and bonded at its other surface to a base layer of a thermoplastic ethylene interpolymer (e.g., an ethylene-vinyl acetate copolymer). The product is useful as a floor or wall covering.
