Process for manufacturing solid electrochromic element
First Claim
1. A process for manufacturing solid electrochromic element which comprises the following steps:
- (1) forming a first electrode layer on a substrate by the ion plating technique, (2) forming one of an oxidation color-developing layer and a reduction color-developing layer on said first electrode layer, (3) forming an ion-donating layer on said one of the color-developing layers by the ion plating technique, (4) forming the other reduction color-developing layer and the oxidation color-developing layer on said ion-donating layer, and (5) forming a second electrode layer on the other color-developing layer by the ion plating technique.

Abstract
The solid electrochromic element of this invention is to be used for various types of dimmers and displays, and comprises a pair of electrode layers, an oxidation color-developing layer, an ion-donating layer and a reduction color-developing layer laminated one upon another on a substrate. In the manufacture of this type of electrochromic element, the pair of electrode layers and the ion-donating layer are formed by the ion plating technique.
The dimmers of this invention for automotive sun roof, side-watching window and glare-free mirror each contains an electrochromic element manufactured by the process mentioned above. The light transmittance of the sun roof and side-watching window, as well as the intensity of reflecting light at the glare-free mirror, are appropriately controlled according to the conditions of their use by application of a variable voltage across the two electrode layers of the electrochromic element.
