摘要

Laminated, decorative, relief-patterned, foamed, flooring or wall-covering has 1 lamina of cellular polymer with raised zones sepd. by depressed zones, with 1 main protective layer covering at least the raised zones. There are also a 1st and a 2nd, non-foamed, laminae >=1 of which is discontinuous. Each non-foamed layer is >=0.5 mm thick and has dissimilar colouring and/or transparency. At least parts of both these layers are exposed to view. The claimed prod. may have a backing e.g. of asbestos fibre felt. The foamed laminas is pref. of PVC foam. The non-foamed, protective, layers are pref. polyurethane lacquers. Those parts devoid of the main protective layer have a protective layer up to 0.04 mm thick. The whole surface of the prod. may be protectively coated with transparent layer up to 0.04 mm thick.
