Abstract
Decorative sheet materials such as foamed vinyl floor coverings comprising, preferably, a base or substrate such as asbestos felt, a layer of foam or cellular resin material on the base having portions of different thickness providing a relief pattern, the foam of the lands having relatively large cells and the foam of the valleys being crushed and having smaller cells with cell walls bonded to each other, a layer of non-cellular transparent resin material overlying both the land and valley areas of the relief pattern, and a printed color pattern or design being provided between the foam resin layer and the transparent resin layer, with colored areas of the pattern or design in accurate registration with and/or predetermined relation to the crushed or valley areas of the foam layer. In addition to the relief and color patterns, the product may also have a third pattern effect in registration with the relief and color patterns, i.e., a pattern of different light reflective characteristics at the exposed surface of the transparent layer. Apparatus and method for producing the covering materials according to the invention are also disclosed.
