Claim 1
Independent Claim
187 words
An electrochromic nonglaring mirror, comprising: a transparent first substrate of which the inside surface is laid with a transparent first electrode layer; a first electrochromic layer laid on said first electrode layer and formed of an organic polymer which undergoes electrochemical oxidation and reduction in at least two states and assumes different colors at its respective stages of electrochemical oxidation and becomes pale or colorless in its electrochemically fully reduced state wherein said organic polymer is made up of repeating units represented by the following general formula: ##STR2## wherein X and X' each represent a hydrogen atom, a halogen atom, an alkyl group having not more than 4 carbon atoms or an alkoxyl group having not more than 4 carbon atoms; a second substrate comprising a second electrode layer arranged opposite to said first electrode layer; a second electrochromic layer laid on said second electrode layer; means for holding said first and second substrates spaced from each other and defining a closed space between the two substrates; an electrolyte liquid which occupies said closed space; and reflecting means for providing a reflective surface to said second substrate.
Claim 2
Dependent Claim
187 words
An electrochromic nonglaring mirror, comprising: a transparent first substrate of which the inside surface is laid with a transparent first electrode layer; a first electrochromic layer laid on said first electrode layer and formed of an organic polymer which undergoes electrochemical oxidation and reduction in at least two states and assumes different colors at its respective stages of electrochemical oxidation and becomes pale or colorless in its electrochemically fully reduced state wherein said organic polymer is made up of repeating units represented by the following general formula: ##STR2## wherein X and X' each represent a hydrogen atom, a halogen atom, an alkyl group having not more than 4 carbon atoms or an alkoxyl group having not more than 4 carbon atoms; a second substrate comprising a second electrode layer arranged opposite to said first electrode layer; a second electrochromic layer laid on said second electrode layer; means for holding said first and second substrates spaced from each other and defining a closed space between the two substrates; an electrolyte liquid which occupies said closed space; and reflecting means for providing a reflective surface to said second substrate.
