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.
