ABSTRACT:
An electrolytic material intended for a process relating to a light-modulating cell involving electrochromic reflection or transmission. The electrolytic material is a homogeneous mixture of solid consistency, comprising at least (a) a water-soluble salt or salts of one metal which can be cathodically deposited from an aqueous solution of one of its ions; (b) one initially water-soluble film-forming polymer resin; and (c) water. The material has ionic conductivity and deformability, and can be formed in a thin continuous layer. It has at least the functions of participating in the erasure of a picture element earlier written in the light-modulating cell, and of enabling the flow of electrical current between a working electrode and a counter-electrode during writing and erasure steps.
