Decorative sheet-type covering material and method for making same. The material has a substrate comprising a porous mat saturated and completely coated on both sides with foamed, flexible urethane. The substrate is made by coating one side of a porous mat with reactive urethane mixture which is then allowed to foam.

Decorative covering material

Decorative sheet-type covering material and method for making same. The material has a substrate comprising a porous mat saturated and completely coated on both sides with foamed, cured PVC plastisol or organosol. The substrate is made by coating one side of a porous mat with foamable PVC plastisol or organosol and then heating and foaming the plastisol or organosol.

Sheet backing for decorative covering material

Decorative sheet type covering material and process for making same. The material has a substrate, a foamed vinyl plastic layer over the substrate, a thin unfoamed smooth plastic layer over the foamed layer, a metal layer over the smooth layer and a wear layer over the metal layer.

Sheet type covering material with metallic luster and process for making

Embossed decorative sheet-type covering material such as sheet vinyl flooring is prepared by forming a foamed plastic layer over a pigmented layer on a substrate and then selectively crushing the foamed layer by mechanical embossing to produce selectively crushed transparent portions through which the pigmented layer is visible. Printing is normally included on the upper surface of the plastic layer before the latter is foamed and a conventional wear layer is also preferably used. In a preferred embodiment, a foamed undercoat layer is also used to reduce embossing requirements. Conventional materials are preferred, such as latex coated felt for the substrate, cured, foamed polyvinyl chloride organosol or plastisol for the foamed layers and cured, clear polyvinyl chloride organosol for the wear layer.
