1. A floor panel with a substrate and a decoration provided thereon, said decoration comprising a printed motif, wherein the substrate comprises at least a first and a second substrate layer;
wherein said first substrate layer is a layer of foamed polyvinyl chloride which comprises at least 30 phr of filler materials, and comprises a first content of plasticizers of 0 to 12 phr; said first substrate layer being positioned centrally in the substrate, thus forming at least a substrate portion present in a center of a thickness of the substrate; said first substrate layer forming at least 30 percent of the thickness of said substrate;
wherein said second substrate layer is a layer of plasticized polyvinyl chloride wherein said second substrate layer comprises a second content of plasticizer larger than said first content; wherein said second substrate layer is positioned between said first substrate layer and said decoration;
wherein said first substrate layer is a foamed layer obtained at least by means of a chemical foaming process, wherein the polyvinyl chloride comprises hollow spaces filled with a gaseous reaction product remaining present in the form of bubbles.
