Abstract
The present invention provides a decorative floor covering comprising a surface layer and a substrate layer underneath, wherein the surface layer comprises a polyethylene terephthalate film layer, and a method for preparing the same. Furthermore, the present invention provides a decorative floor covering comprising a surface layer and a substrate layer underneath, wherein a light weight back layer is further comprised under the substrate layer, and a method for preparing the same. A decorative floor covering of the present invention is a decorative floor covering which has superior surface heat resistance, printing sharpness and realism, and it can be installed conveniently since not only can non-foamed polyvinyl chloride resin be used as a substrate layer, but also the weight of a floor covering is light when a light weight back layer is comprised under the substrate layer.
