Abstract

This invention relates to a method for producing a decorative reflective surface covering with improved adhesion of the various layers, having a backing, metallic areas and a transparent top layer, and the product thus produced. This product is produced by applying an adhesive on the surface of a backing in regular, spaced intervals, bringing a metal face of a film in contact with the adhesive to secure it to the backing, removing the metal film whereby the areas in contact with the adhesive remain on the backing and then applying a transparent layer to the surface of the backing covering the remaining metallic areas.

Claims

1. A decorative surface covering having a metallic appearance comprising a base sheet, a first layer of resinous composition on one surface of the base sheet, an adhesive coating located on said first layer in the form of a plurality of spaced-apart fine discrete dots or other shapes such that the resinous composition is exposed to view in the areas not covered with adhesive dots, a plurality of discontinuous metal films covering only said discrete adhesive dots, and a transparent or translucent second resinous composition surface wear layer covering and surrounding each metal film and fused directly to said first resinous composition thereby encapsulating each discrete metal film and securely binding it to the base sheet.

2. The decorative surface covering according to claim 1 wherein said metallic films cover less than 80% total surface area.

3. The decorative surface covering according to claim 2 wherein said adhesive coating is in the form of rotogravure or other type print.

4. The decorative surface covering according to claim 3 wherein said metallic films are vacuum metalized films.

5. The decorative surface covering according to claim 2 wherein said base sheet is a fibrous felt sheet.

6. The decorative surface covering according to claim 2 wherein said first layer of resinous composition is a resin composition foam layer.

7. The decorative surface covering according to claim 2 wherein the resin composition wear layer is a polyvinyl chloride composition.

8. The decorative surface covering according to claim 2 wherein said metallic films have a thickness of from about 1 to about 10 microns.

9. The decorative surface covering according to claim 8 having a decorative layer on the upper surface of said metallic films.

10. The decorative surface covering according to claim 8 having depressed areas on the upper surface of said surface covering.
