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.
