Abstract
An electrochromic material containing a hydrosoluble salt or a hydrosoluble mixture of salts of at least one metal cathodically depositable from an aqueous solution of its ions, an initially hydrosoluble film-forming polymer resin and water. The electrochromic material being able to develop by cathodic reduction of at least one depositable metal ion present within the electrochromic material metal marks.
Claims31
Electrochromic material comprising a homogeneous mixture having a solid consistency and consisting essentially of
- (a) a hydrosoluble salt or a hydrosoluble mixture of salts of at least one metal cathodically depositable from an aqueous solution of its ions;
- (b) an initially hydrosoluble film-forming polymer resin;
- and
- (c) water;
- the electrochromic material being able to develop by cathodic reduction of at least one depositable metal ion present within the electrochromic material metal marks, said metal marks electrocrystallizing as integral parts of the electrochromic material;
- said electrochromic material being electroconductive.

Electrochromic material comprising a homogeneous mixture having a solid consistency and consisting essentially of
- (a) a hydrosoluble salt or a hydrosoluble mixture of salts of at least two metals cathodically co-depositable from an aqueous solution of their ions;
- (b) an initially hydrosoluble film-forming polymer resin;
- and
- (c) water;
- the electrochromic material being able to develop by cathodic reduction of at least two co-depositable metal ions present within the electrochromic material metal alloy marks, said metal alloy marks electrocrystallizing as integral parts of the electrochromic material;
- said electrochromic material being electroconductive.
