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.
Claims9
A heat processable, metallic appearing coated article comprising:
- a transparent glass substrate;
- a metallic appearing metal-containing film deposited on a surface thereof;
- an amorphous metal oxide layer over the metallic appearing metal containing film;
- and
- a protective layer comprising a different metal from the metal-containing film deposited over the amorphous metal oxide layer.
