1. A method for fabricating an electrochromic article comprising the steps of:

  • (a) depositing an organic polymer primer coating on a surface of each of two organic polymer substrates,(b) depositing an electroconductive metal oxide film on each of the primer coatings deposited on said organic polymer substrates,(c) depositing a film of an electrochromic material on one of the electroconductive metal oxide films deposited in step (b),(d) depositing a film of a complementary electrochromic material on the other electroconductive metal oxide film deposited in step (b),(e) assembling the organic polymer substrates of steps (c) and (d) in spaced relationship with the electrochromic and complementary electrochromic films in a facing relationship,(f) disposing a preformed sheet of ion-conducting polymer between and in contact with the electrochromic and complementary electrochromic films, and(g) applying heat and pressure to laminate said sheet to said electrochromic films.
