Abstract:
1. An all-solid-state reflective dimming electrochromic element having a multilayer film formed on a transparent substrate, wherein: the multilayer film has a multilayer structure comprising at least a transparent conductive film layer, an ion storage layer, a solid electrolyte layer, a buffer layer, a catalyst layer, a reflective dimming layer comprising a magnesium alloy thin film, and a protective layer formed successively on the transparent substrate; the protective layer comprises an ultraviolet curing resin, an ultraviolet-heat curing resin, a polyvinyl chloride, a polyvinylidene chloride, a fluororesin, tetrafluoroethylene, or a cycloolefin polymer; the protective layer seals the reflective dimming layer surface or the multilayer film; the protective layer does not chemically react with the other layers of the multilayer film; and the protective layer has a cure shrinkage of 10% or less, a water absorption of 3% or less, and a total transmittance of 90% or more and is transparent if cured.
