Resilient flooring product and methods of making same

A floor covering comprising:

• a backing portion having a first surface and a second surface, wherein the second surface of the backing portion is opposed to the first surface of the backing portion;
• a decorative portion having a first surface and a second surface,
• wherein the second surface of the decorative portion is opposed to the first surface of the decorative portion,
• wherein the decorative portion is disposed above the backing portion such that the second surface of the decorative portion faces the first surface of the backing portion,
• wherein the decorative portion comprises a substrate layer and an UV cured ink layer that overlies at least a portion of the substrate layer;
• a tie layer comprising an adhesive composition,
• wherein the adhesive composition comprises a polyurethane-based adhesive;
• and
• wherein the tie layer substantially overlies the decorative portion such that at least a portion of the tie layer adheres to the decorative portion;
• and
• a wear layer substantially overlying the tie layer such that at least a portion of the wear layer adheres to at least a portion of the tie layer;
• and
• a scratch layer disposed above the wear layer, the scratch layer being a UV-cured layer,
• wherein the wear layer exhibits a pull value greater than about 5 pounds as determined by ASTM 3936 with a 1-inch by 6-inch strip pulled at a rate of 2 inch/min for a pull distance of 2 inches.
