Abstract:
An all-solid type electrochromic mirror comprising a reflective electrically conductive substrate, a transparent electrically conductive substrate, a layer of a solid ion conductive material, said solid ion conductive material disposed between said reflective electrically conductive substrate and said transparent electrically conductive substrate, and at least one electrochromic chromogenic layer disposed either between said ion conductive material layer and said reflective electrically conductive substrate or between said ion conductive material layer and said transparent electrically conductive substrate, wherein said ion conductive material comprises a polymer solid electrolyte derived from the polymerization of a compound selected from polyethyleneoxide-based compounds, oxyalkyleneacrylate-based compounds and urethaneacrylate-based compounds, and wherein said electrochromic chromogenic layer contains a compound having a viologen structure selected from polymers and copolymers represented by the formula ##STR24## wherein m is an integer of more than 1, n is an integer of more than 0, R.sup.33 is a C.sub.1 -C.sub.20 divalent hydrocarbon residue, R.sup.34, R.sup.35 and R.sup.36 are each independently a C.sub.1 -C.sub.20 hydrocarbon group, a hetero atom-containing substituent, or a halogen atom, and X.sup.- and Y.sup.- represent counter anions selected from the group consisting of F.sup.-, Cl.sup.-, Br.sup.-, I.sup.-, ClO.sub.4.sup.-, CH.sub.3 COO.sup.-, and CH.sub.3 (C.sub.6 H.sub.4)SO.sub.3.sup.-, with respect to viologen and maybe the same or different; or the formula ##STR25## wherein m is an integer of more than 1, n is an integer of more than 0, R.sup.37 and R.sup.38 are each independently a C.sub.1 -C.sub.20 divalent hydrocarbon residue, R.sup.39 and R.sup.40 are each independently a C.sub.1 -C.sub.20 hydrocarbon group, a heteroatom-containing substituent, or a halogen atom, and X.sup.- and Y.sup.- represent counter anions selected from the group consisting of F.sup.-, Cl.sup.-, Br.sup.-, I.sup.-,ClO.sub.4.sup.-, CH.sub.3 COO.sup.-, and CH.sub.3 (C.sub.6 H.sub.4)SO.sub.3.sup.-, with respect to viologen and maybe the same or different.
