A method and composition for providing a colored high performance wear surface for floor coverings is disclosed. Specifically, the floor covering includes a substrate and a high performance layer comprising a radiation cured pigmented composition. The exposed surface of the floor covering has a stain resistance of less than about 150 Delta E units. A pigmented high performance wear layer can be added in register with a printed design on the substrate or in register with an embossed texture of the substrate. Additionally, a high performance topcoat wear layer may be added. The pigmented high performance layer may include a nacreous pigment.

Pigmented radiation cured wear layer

A preseamed, resilient sheet flooring including first and second composite sheet products positioned closely adjacent each other edge-to-edge to form a seam therebetween. An adhesive is positioned in the seam. The adhesive extends completely through the thickness of the sheet flooring, bonds with the first and second sheet products through the entire thickness thereof, and has visual characteristics suitable for creating an indistinct appearance of the seam in the sheet flooring product. The adhesive also has wear characteristics sufficiently similar to wear characteristics of the sheet flooring to maintain the visually indistinct appearance of the adhesive on the surface of the seam as wear occurs to the sheet flooring, thereby creating a finished seam sufficiently strong and flexible to permit the adhesive to be positioned in the seam prior to unrolling the flooring onto a subfloor surface.
