Abstract
An electrochromic article comprising plastic substrates and a method for constructing such an article are disclosed wherein two plastic substrates are coated with a primer to adhere an electroconductive metal oxide film, onto which are deposited an electrochromic film and a complementary film respectively. The two coated plastic substrates are assembled to form a cavity into which is placed a solution of monomers which are polymerized to form an ion-conducting copolymer.
