Abstract
An electrochromic mirror device suitable for use in a vehicle comprises a first transparent substrate having a transparent conductive layer on a surface thereof and a second substrate having a conductive layer on a surface thereof. The conductive layer of the first substrate opposes the second conductive layer of the second substrate in a spaced-apart relationship thereby forming an interpane distance between the substrates. A boundary seal is interposed between the first and second substrates spacing apart the substrates and forming a cavity wherein the interpane distance is at least about 10 microns. An electrochromic cross-linked polymeric solid film is disposed within the cavity. The electrochromic cross-linked solid polymeric film is formed from an electrochromic monomer composition that includes at least one cathodic electrochromic compound. The second conductive layer comprises a metallic reflective layer.
