1. An electrochromic device for use in a mirror for performing color change of the mirror in response to a voltage applied thereto, comprising:
- a first transparent substrate;
a second transparent substrate positioned substantially parallel to said first transparent substrate, and spaced apart from said first transparent substrate by a predetermined clearance to form a space therebetween;
an electrochromic composition including a hydrazone compound, disposed in said space between said first and second transparent substrates;
a seal disposed between said first and second transparent substrates for retaining said electrochromic composition in said space; and
a pair of transparent electrodes provided on opposite surfaces of said first and second transparent substrates facing said space for providing said voltage for said electrochromic composition to perform color change wherein said hydrazone compound is a member selected from a group consisting of 4-diphenylamino-benzaldehyde-N,N-diphenylhydrazone, 9-ethyl-carbazole-3-aldehyde-N,N-methylphenyhydrazone, Ferrocenemethylketone-N,N-diphenylhydrazone, Benzophenone-N,N-diphenylhydrozone, Acetone 2,2-dimethylhydrazone, 2-pentanone 2-ethyl-2-methyihydrazone, 2-ethylbutanal 1-ethyl-1-propylhydrazone, 2-ethyl-2-nonanone 2-hexyl-2-propylhydrazone, (E)-3-nonen-2-one 2-butyl-2-propyihydrazone, 2-hexanone 2-[(E)-2-butenyl]-2-[(Z)-2-butenyl]hydrazone, 4-pentyn-2-one 2,2-dipropyihydrazone, 1-penten-3-one 3,3-dimethyihydrazone, 2-hexanone 2,2-diphenyihydrazone, 3-heptanone 3-methyl-3-phenylhydrazone, 1-ethoxy-2-butanone 2-methyl-2-phenylhydrazone, 1-phenylacetone 2-(3-methoxyphenyl)-2-phenylhydrazone, 2-phenacetaldehyde 1-methyl-1-phenylhydrazone, methyl 3-[(Z)-2-methyl-2-phenylhydrazone]-butanethioate, 1-(3-chlorophenyl)-3-methoxy-1-propanone 1-methyl-1-(3-methylphenyl)hydrazone, Ferrocenephenylketone 2-[(E)-2-butenyl]-2-[(Z)-2-butenyl] hydrazone, Bis(cyclopentadienyl)Cobaltmethylketone 2,2-diphenylhydrazone, Bis(cyclopentadienyl) dimethyizirconiummethylketone 2,2-diphenyihydrazone, 1-phenyl-1-ethanone 1,1-di(2-methoxyethyl)hydrazone, 1-[3-(dimethylamino)phenyl]-1-ethanone 1,1-diethylhydrazone, 2-[(Z)-2,2-diethylhydrazono]propyl cyanide, 2-[(E)-2-ethyl-2-phenylhydrazono]-3-methoxypropyl cyanide, (Z)-1-chloro-1-penten-3-one 3-methyl-3-phenylhydrazone, and 2-propynal 1-[4-(dimethylamino)phenyl]-1-methylhydrazone.
