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.
A coated glass plate, comprising a transparent or semitransparent glass plate and a multilayer coating film which is provided on one side of the glass plate and comprises a TiN layer adjacent to the glass plate surface and a layer of a metal selected from the group consisting of Ti and Cr which overlies said TiN layer, said multilayer coating film being formed such that the transmittance of the coated glass plate for visible light is not more than 40%.
