ELECTROCHROMIC DEVICE HAVING A SELF-CLEANING HYDROPHILIC COATING WITH AN ACID RESISTANT UNDER LAYER

摘要

A variable reflectance rearview mirror for a vehicle (20), comprising: (a) a variable reflectance mirror element (100) having a reflectivity that varies in response to an applied potential so as to exhibit at least a high reflectance state and a low reflectance state; (b) a self-cleaning, hydrophilic coating (130) applied to a front surface of said mirror element; and (c) an acid resistant layer (131) applied to a surface of the self-cleaning hydrophilic coating.
