Laminated electrochromic devices and processes for forming the same
First Claim
1. An electrochromic device formed by assembling a pair of substrates having conductive layers with a preformed multi layer film formed independently of the conductively coated substrate, wherein the device is assembled with the conductive layers of the substrates facing inwards and sandwiching the pre-formed multilayer solid film wherein the said preformed multi layer film comprises at least two layers with different compositions, and at least one of these layers having electrochromic properties and at least one layer having electrolytic properties.
