ABSTRACT:
A stain-adsorbing backing sheet for use with a decorative surface covering; a decorative surface covering comprising a stain-adsorbing backing sheet; and a method for forming a stain-adsorbing backing sheet for a decorative surface covering. The backing sheet comprises an additive which is effective in adsorbing a stainant that comes into contact with the backing sheet and which is present in an amount effective to reduce the degree of staining which tends to be visible in the top surface of the covering. The additive is preferably an adsorbing material that does not affect adversely the visual characteristics of the sheet and surface covering.
