摘要： The present invention discloses a surface covering, in particular floor or wall covering, comprising at least one polymer layer comprising a blend of polymers, said blend of polymers comprising from 6.5 to 93.5% by weight of a cellulose ester and from 93.5 to 6.5% by weight of one or more polymers selected from the group consisting of (meth)acrylate comprising (co)polymers, vinyl alkanoate comprising (co)polymers, vinylacetals (co)polymers, (co)polyesters, (co)polyamides, polyurethanes, nitrile (co)polymers, styrene (co)polymers, vinylchloride (co)polymers, olefin (co)polymers, and ionomers.

摘要： The present invention discloses a surface covering, in particular a floor or wall covering comprising: - a substrate A, having an upper and a lower surface, said substrate (A) being characterized by a deformation of less than 40 degrees, preferably of less than 30 degrees, more preferably of less than 20 degrees, most preferably of less than 10°, as measured for a rectangular substrate A sample with dimensions of 160 mm×450 mm, partially contacting and fixed in a horizontal position to a plate support, so that exactly a 160×300 mm part of said sample exceeds the edge of the plate support and is free of support during the deformation measurement, ● the deformation being recorded 30 seconds after removing means that prevent a deformation of the 160×300 mm part under the influence of its own weight, ● the deformation, being the angle, in degrees, between the horizontal position and the position after 30 seconds, of the extreme bottom edge of the freely suspended 160×300 mm part of said rectangular substrate sample (A), free of support and deforming under its own weight away from the horizontal position; - a scuff resistant polymer layer B, having an upper and a lower surface, said polymer layer B comprising one or more polymer(s) C, said one or more polymer(s) C comprising more than 93.5% by weight of cellulose ester polymer(s); the lower surface of polymer layer B contacting and adhering to the upper surface of substrate A.
