EMBOSSED DECORATIVE SHEET-TYPE MATERIAL AND PROCESS FOR MAKING SAME Abstract of the Disclosure 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 conven- tional wear layer is also preferably used. In a preferred embodiment, a foamed undercoat layer is also used to reduce embossing requirements. Conventional materials are pre- ferred, 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.
