First Claim
1. An electrochromic window comprising:
- a first transparent substrate having a first electrically-conductive coating over at least a portion thereof;
a second transparent plastic substrate having a second electrically-conductive coating over at least a portion thereof, wherein the second electrically-conductive coating comprises a metal layer located between first and second metal oxide layers; and
an electrochromic medium located between the first and second electrically-conductive coatings, wherein the second substrate includes a primer layer located between the second substrate and the second electrically-conductive coating.

Abstract
An electrochromic window includes a first transparent, e.g., plastic, substrate having a first primer over at least a portion thereof and a first electrically conductive coating over at least a portion of the first primer. A second transparent plastic substrate has a second primer over at least a portion thereof and a second electrically conductive coating over at least a portion of the second primer. The first primer has a coefficient of expansion less than the coefficient of expansion of the first plastic substrate, and the second primer has a coefficient of expansion less than the coefficient of expansion of the second plastic substrate. An electrochromic medium is located between the first and second electrically conductive coatings. At least one of the first and second electrically conductive coatings has a metal layer located between first and second metal oxide layers.

-
a first transparent plastic substrate having a first primer layer over at least a portion thereof and a first electrically-conductive coating over at least a portion of said first primer layer, said first primer layer comprising a multi-film coating comprising at least a first primer film overlaying at least a portion of the first substrate and having a coefficient of expansion less than that of the first substrate, and a second primer film overlaying at least a portion of the first primer film of the first primer layer and having a coefficient of expansion less than that of the first primer film of the first primer layer;
a second transparent plastic substrate having a second primer layer over at least a portion thereof and a second electrically-conductive coating over at least a portion of said second primer layer, said second primer layer comprising a multi-film coating comprising at least a first primer film overlaying at least a portion of the second substrate and having a coefficient of expansion less than that of the second substrate, and a second primer film overlaying at least a portion of the first primer film of the second primer layer and having a coefficient of expansion less than that of the first primer film of the second primer layer; and
an electrochromic medium located between the first and second conductive coatings. - View Dependent Claims (24, 25)
