A multiple-layer, high transmittance, low emissivity coated article is disclosed comprising at least two infrared reflective metal layers alternatingly combined with at least three metal oxide antireflective layers to produce a coating with superior low emissivity and low visible reflectance, especially for use to reduce heat load in automobiles, wherein the coating furthermore is electroconductive for use in an electrically heatable transparency.

[ I claim:] [1.] An electrically heatable transparency comprising a glass sheet, a transparent electroconductive coating on a major surface of the sheet, a first bus bar in contact with the coating along a first edge portion of the sheet, a second bus bar in contact with the coating along a second edge portion of the sheet opposite the first edge portion, an electroconductive extension extending from each end of the second bus bar to the first edge portion along third and fourth edge portions respectively, the extensions being electrically insulated from the coating, wherein the coating comprises:a. a first transparent antireflective metal oxide film of an oxide reaction product of zinc and tin deposited on a surface of said glass sheet;b. a primer layer of titanium on said first transparent antireflective film;c. a transparent infrared reflective silver film deposited on said antireflective metal oxide layer;d. a first transparent metal-containing primer layer comprising titanium deposited on said infrared reflective metallic film; ande. a second transparent antireflective metal oxide film of an oxide reaction product of zinc and tin on said primer film; in combination withf. a second transparent metal-containing primer layer comprising titanium on said second antireflective metal oxide film;g. a second transparent infrared reflective silver film deposited on said second transparent titanium primer film;h. a third transparent metal-containing primer layer comprising titanium deposited on said second infrared reflective silver layer; andi. a third transparent antireflective metal oxide film of an oxide reaction product of zinc and tin deposited on said third primer layer, andj. a protective metal-containing overcoat deposited over said third antireflective metal oxide film.
