The present invention relates to electrochromic polymeric solid films, manufacturing electrochromic devices using such solid films and processes for making such solid films and devices. The electrochromic polymeric solid films of the present invention exhibit beneficial properties and characteristics, especially when compared to known electrochromic media. The electrochromic polymeric solid films are transformed in situ from a low viscosity electrochromic monomer composition by exposure to electromagnetic radiation, and in so doing minimum shrinkage occurs. The electrochromic polymeric solid films of the present invention also perform well under prolonged coloration, outdoor weathering and all-climate exposure, and provide an inherent safety aspect not known to electrochromic media heretofore.

[ What we claim is:] [1.]1. A method of disposing a solid polymer film between two opposing, spaced substrates of an electrochromic device, said method including the steps of:providing a first substrate of the electrochromic device, said first substrate comprising a first substantially transparent element having a first transparent conductive surface;providing a second substrate of the electrochromic device, said second substrate comprising a second element having a second conductive surface;opposing the conductive surface of said first substrate with the conductive surface of said second substrate and spacing said substrates apart with a solid spacer, said spacer and said substrates forming an interpane cavity between said first and second substrates;providing a low viscosity monomer composition that includes at least one of (A) a monofunctional monomer and a cross-linking agent and (B) a polyfunctional component capable of cross-linking, said monomer composition further including a plasticizer;causing said low viscosity monomer composition to flow into said interpane cavity; andwith the monomer composition disposed within said interpane cavity, in-situ curing said monomer composition to form a cross-linked solid polymer film.
