Abstract:
1. An electrochromic transparency comprising: first and second spaced apart transparent substrates defining a chamber there between, said first and said second substrates including first and second electrically conductive transparent coatings on respective facing surfaces thereof; and an electrochromic medium contained in said chamber, said electrochromic medium having reduced luminous transmittance upon application of electrical power to said first and second electrically conductive coatings to establish an electrical potential through said electrochromic medium, said electroconductive medium comprising an electrochromic solution dispersed in a polymeric matrix; wherein at least one of said first and said second substrates is plastic, and at least one of said first and second electrically conductive coatings is affixed to said plastic substrate through a transparent primer composition which is compatible with said electrochromic medium.
