Process for manufacturing an electrochromic article

Abstract

The present invention relates to a process for manufacturing an electrochromic article, comprising the following successive steps: (a) deposition of a layer of an electrochromic compound on the surface of a transparent or translucent electroconductive substrate; (b) deposition of a redox agent, which is a reducing agent or an oxidizing agent for the electrochromic compound, on the layer of electrochromic compound at a multitude of discrete points or areas thereon; (c) bringing the layer of electrochromic compound, deposited in step (a), and the redox agent, deposited in step (b), into contact with a liquid electrolyte for a time long enough to allow the electrochromic compound to be reduced or oxidized by the redox agent; and (d) elimination of the electrolyte by rinsing and/or drying, the layer of electrochromic compound being a porous layer of open porosity and/or an electrically conductive layer.
