ABSTRACT:
FIELD OF THE INVENTION
The instant invention relates to a substrate having a leveling plastic coating thereon, a decorative zirconium nitride layer on the plastic coating, and a protective polyurethane coating over the zirconium nitride layer.
SUMMARY OF THE INVENTION
In accordance with this invention a plastic basecoat is provided on the surface of the substrate. The polymeric basecoat provides a leveling effect to the surface of the substrate. A decorative zirconium compound or titanium compound layer is then applied onto the basecoat. A protective polyurethane top coat is provided over the zirconium compound or titanium compound layer.
BACKGROUND OF THE INVENTION
Thin zirconium compound or titanium compound layers have been applied by vapor deposition onto the surfaces of various substrates to provide a decorative and shiny appearance thereto. However, the substrates have had to be pretreated as by drying, polishing, cleaning and the like to remove any stains, spots, scratches or other imperfections from their surfaces before the zirconium compound or titanium compound layer is applied thereon. Otherwise, the zirconium compound or titanium compound layer will enhance and accentuate these imperfections. Also, the zirconium compound or titanium compound layer, while quite hard, is nevertheless subject to abrasion, scratching and weathering, particularly if it is applied onto a part of a vehicle such as, for example, a wheel cover.
The present invention provides a substrate having a decorative zirconium compound or titanium compound layer which is not subject to the afore-mentioned disadvantages.
