Abstract
An electrochromic device including one electrode layer (A), a cathodically coloring electrochromic layer (B), an ionic conductive layer (C) if required, a reversibly oxidizable layer (D) and another electrode layer (E), at least one of the one electrode layer (A) and the other electrode layer (E) being transparent, and at least one of the cathodically coloring electrochromic layer (B), the ionic conductive layer (C) and the reversibly oxidizable layer (D) being adapted to contain protons or include a proton source for emitting protons upon application of a voltage. The reversibly oxidizable layer (D) comprises a transparent dispersion layer (D1) which is made by vacuum thin film formation techniques or thick-film processes and which comprises a metal iridium, iridium oxide or iridium hydroxide disperse phase (D11) and a transparent solid dispersion medium (D12), or the reversibly oxidizable layer (D) and the other electrode (E) are replaced with a single transparent conductive dispersion material layer (D1a) which is made by vacuum thin film formation techniques or thick-film processes and which comprises a metal iridium, iridium oxide or iridium hydroxide disperse phase (D11) and …
