  • Patent number: 5800904
    Abstract: A composite surface covering includes a substrate and an inorganic wear layer. The composite surface covering retains its performance characteristics after mechanical embossing. Preferably, the inorganic wear layer of the surface covering is deposited on the substrate by a reduced pressure environment vapor deposition technique. Preferably, the inorganic wear layer is aluminum oxide. The preferred substrate is a plastic material.
    Type: Grant

  • Patent number: 5188876
    Abstract: A surface covering is a laminate including a hard inorganic wear layer deposited on a support by a reduced pressure environment technique such as ion assisted physical vapor deposition. The support may be selected from metal foils, films or sheets and plastics, rubbers or mineral/binder systems. The preferred support materials include organic materials. The wear layer is between 1 micron and 25 microns in thickness and has a CIE LAB value of total Delta E of less than 12. Preferably, the wear layer is deposited on the support at a temperature of less than 175.degree. C.
