Problems solved by technology

Here, for example, Na contained in the atmosphere + When such cations penetrate into the electrochromic element, the conductivity of the proton is lowered to hinder the reaction, and the desired anti-glare effect cannot be obtained.
[0012] In the above-mentioned Patent Document 1, the density of the silicone-based or urethane-based polymer used as a synthetic resin material is increased by utilizing a cross-linked structure, and metal oxides, ceramics, and glass powder are contained in the resin film to prevent The intrusion of ions into the electrochromic element, but its effect is not necessarily sufficient

Embodiment

[0074] by ion plating with The film thickness is evaporating ITO on the glass substrate to form a transparent electrode film with a transmittance of 90% or more and a sheet resistance of 10Ω / □ or less. Then, by ion plating in the same way, the total film thickness is (IrO 2 : SnO 2 : ) by evaporation of IrO 2 +SnO 2 And form an oxidation chromogenic film with a transmittance of more than 80%. Then similarly by ion plating with The film thickness evaporated Ta 2 o 5 And form an electrolyte membrane with a transmittance of 90% or more. by electron beam evaporation to The film thickness evaporates WO on the above electrolyte membrane 3 And form a reduced chromogenic layer with a transmittance of 95% or more. On the above-mentioned reduced chromogenic layer, in contact with it, by a resistance heating evaporation method or the like to Al is vapor-deposited to a thickness of 10000 Ω to form a reflective and electrode film with a sheet resistivity of 10Ω / □ or hi...

Abstract

As the protective insulating layer covering the outer surface of the electrochromic element of the electrochromic mirror, a coating film made of a synthetic resin material is used instead of a conventional glass substrate, and sufficient durability against the use environment can be ensured. As the above-mentioned synthetic resin material, a solvent-soluble fluorine-based copolymer resin containing a copolymer of a fluoroolefin-based monomer and an acrylate-based monomer is used, which is dissolved in a solvent to prepare a coating liquid, and then formed A protective insulating layer covering the outer surface of the electrochromic element and the stacked end faces of each film.

Description

technical field [0001] The present invention relates to an electrochromic mirror, and in particular to using a synthetic resin protective insulating layer which is excellent in comprehensive protection functions including various environmental resistances necessary for an electrochromic mirror, is light in weight, and is easy to manufacture and process as a protection for the electrochromic mirror. The electrochromic element of the electrochromic mirror is an electrochromic mirror that protects the base material from the external environment in which it is used. Background technique [0002] Electrochromic mirrors have been put into practical use in rearview mirrors and the like for automobiles. The principle of the electrochromic mirror is to provide coloring / decolorization by oxidation / reduction reaction between the surface side (visible side) substrate and the back side (reflection side) substrate of the mirror in order to prevent glare when driving at night, etc. The ch...
