Abstract
The invention relates to an electrochromic device comprising a pair of transparently and conductively coated glass or plastic plates, one of which is optionally mirrored and the conductive layer of one or both of which is optionally subdivided into separate individually electrically contacted segments, wherein(1) the plates are joined together on the sides of their conductive coating by an adhesive bead into which spacers are optionally embedded, wherein the adhesive used for the adhesive bead is a thermally or photochemically curing epoxy adhesive or an epoxy adhesive that cures thermally after photochemical initiation,(2) the volume formed by the two plates and the adhesive bead is filled with an electrochromic fluid through one or more apertures, and(3) the filling aperture or apertures required for introduction of the electrochromic fluid are sealed with an adhesive after filling has taken place, wherein the adhesive used for sealing is a photochemically curing acrylate adhesive or an epoxy adhesive that cures photochemically or following photochemical initiation at room temperature.
