ABSTRACT:
The invention relates to coated glass substrates for obtaining a variable degree of light transmission therethrough. The coated substrate comprises successively, (1) a first transparent support plate, preferably formed of glass, (2) a transparent electroconductive layer, (3) a layer of an electrochromic material, (4) a proton conductive electrolytic layer having an organic polymer base, (4a) an optional counterelectrode layer, (5) a second electroconductive layer and (6) a second transparent support plate. A proton conductive polymer is selected for the electrolyte whose conductivity is greater than or equal to ##EQU1## wherein the layer has a thickness of less than 50 micrometers.
