ABSTRACT:
The present invention is directed to a barrier layer which has the ability to substantially prevent the diffusion of stains, such as plasticizers and dyes or other chemicals, onto a surface of a surface covering, from a surface or object in which the surface covering is placed upon. The barrier layer contains a polyamide or polyurethane and is preferably located above a substrate or base layer in a surface covering. The barrier layer preferably is located between a UV topcoat layer and a vinyl wear layer. The present invention also relates to a method of preventing stain migration onto a surface covering from a surface on which the surface covering is placed by use of the barrier layer of the present invention and also relates to methods of making surface coverings containing the barrier layer of the present invention.
