ABSTRACT:
An electrochromic variable transmission glazing comprising first and second glass sheets substrates which are joined by an organic polymer whose proton conductivity is greater than or equal to 10.sup.-5 ohm.sup.-1 cm.sup.-1 at 20.degree. C. The glass sheets are coated on their joining faces with transparent electroconductive layers. The first transparent substrate further comprises a layer of electrochromic material, such as tungsten oxide, in contact with the proton conductive polymer. The glazing is characterized by an iridium oxide layer on the second transparent substrate which is interposed between the layer of electroconductive material and the organic polymer. The glazing further comprises a pair of current leads attached to the electroconductive layer which connect the glazing to a generator.
