  • Embossable surface covering with inorganic wear layer
    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.

  • Method to produce an inorganic wear layer
    Patent number: 5505808
    Abstract: Vapor deposited metal nitride or oxide thin films serve as a wear layer for surface coverings after being formed on a release layer and transferred to an organic layer. A release layer such as sodium chloride on glass can be dissolved by water; while a self-supporting release layer can be removed by solvent, etching, laser abatement, or delamination.
