ABSTRACT:
A temperable coated article with metallic properties is prepared by coating a glass substrate with a metal-containing film such as titanium nitride, which ordinarily oxidizes at high temperature, overcoating with a protective layer of a silicon compound which forms a durable layer and prevents oxidation of the underlying metal-containing film and undercoating with a stabilizing metal-containing layer. The coated article can be tempered without losing its metallic properties to oxidation.
