Abstract
The present invention relates to a process for manufacturing an electrochromic article comprising the following successive steps: (a) the deposition of a layer of an electrochromic compound on the surface of a transparent or translucent electrically conductive substrate, said layer of electrochromic compound covering only one portion of the surface of said electrically conductive substrate and leaving free at least one other portion thereof, (b) the deposition of a redox agent which is a reducing agent or an oxidizing agent for the electrochromic compound, on the portion of the surface of the electrically conductive substrate not covered by the layer of electrochromic compound, (c) the contacting of the layer of electrochromic compound, deposited in step (a), and of the layer of redox agent, deposited in step (b), with a liquid electrolyte for a sufficient time to enable the reduction or the oxidation of the electrochromic compound by the redox agent, and (d) the removal of the electrolyte by rinsing and/or drying.
