ABSTRACT:
A heat processable metallic appearing coated article is prepared by coating a glass substrate with a metal-containing film such as chromium or titanium nitride, which ordinarily oxidizes at high temperature, and overcoating with a protective layer of a different metal which forms a dense oxide surface layer. The coated article is subjected to high temperature processing such as bending without losing its metallic appearance to oxidation.
