  • Patent number: 4787717
    Abstract: A pigment is mixed with an epoxy resin or varnish binder in a weight ratio from 5:1 to 6:1 to make a paste, which is then applied as a thin layer by screen printing on top of the counterelectrode layer previously baked onto a metal substrate. In another baking step the new layer for producing a reflective coating is heated to between 120.degree. and 180.degree. C., in which temperature range the binder produces small bubbles before hardening, so that the layer that is produced is permeable to ions when the layer becomes soaked with electrolyte in the assembled electrochromic device. The metal substrate is shaped by drawing to provide the electrolyte cavity after the application of the counterelectrode and the reflecting background layer thereon, since the deformation does not damage either of these layers.
