Title: MULTILAYER SUBSTRATE FOR ELECTROCHROMIC LIGHT CONTROL ELEMENTS AND METHOD FOR PRODUCING ELECTROCHROMIC LIGHT CONTROL ELEMENT
Abstract:
A multilayer substrate for electrochromic light control elements, which comprises a glass substrate and a transparent conductive film, and wherein: the glass substrate contains silicon oxide, aluminum oxide, boron oxide, alkaline earth metal oxides and alkali metal oxides in a total amount of 90 mol% or more, while containing the alkali metal oxides in a total amount of 12 mol% or less; the transparent conductive film sequentially comprises, from the glass substrate side in the following order, an indium oxide film containing tin and a tin oxide film containing one or more elements selected from among tantalum, antimony and fluorine; the indium oxide film is formed directly on the glass substrate and has a refractive index lower than 0.4 and an extinction coefficient higher than 0.4; and the tin oxide film has a film thickness of more than 35 nm but 150 nm or less.
