ABSTRACT:
A multilayer coating film is provided on one side of a transparent or semitransparent glass plate to afford a golden appearance to the coated glass plate at least when viewed from the uncoated side. Essentially the multilayer coating film is made up of a TiN layer adjacent to the glass plate surface and either a Ti layer or a Cr layer which overlies the TiN layer, and the coating film is formed such that the transmittance of the coated glass plate for visible light becomes not more than 40%. Optionally, the Ti or Cr layer is overlaid with either a TiO.sub.2 film or a Cr.sub.2 O.sub.3 film. Also optionally, either a TiO.sub.2 film or a Cr.sub.2 O.sub.3 film is interposed between the TiN layer and the glass plate surface. Each layer of the multilayer coating film can be formed by sputter deposition using a relatively simple method, an the multilayer coating has good durability.
