WLC:SLW 5685 7-11-78 MULTI-LEVEL EMBOSSED CELLULAR SURFACE COVERING Abstract of the Disclosure The process for making a cellular surface covering having a multi-level embossed decorative wear surface by applying to a porous substrate a plurality of thermoplastic resinous inks developed from binders having different melt viscosities, the inks and substrate com- prising a composite structure which also includes a blowing agent. The blowing agent may be either in the substrate or in the inks applied thereto. Upon final heating to fuse and foam all the resinous material of this structure, the melt viscosity differences of the resins in the inks provide varying degrees of physical resistance to expansion of the total system in the inked areas, thus producing multi-level design areas on the final product.
