Abstract: An electrochromic mirror assembly is described that is substantially resistant to seal breaches caused by dendrite formation along adjacent layers of the laminate structure of the assembly. The laminate structure is preferably assembled in a water free environment and includes materials that prevent or inhibit the formation of dendrites between adjacent layers of the laminate structure. By way of a non-limiting example, an electrically conductive layer comprised of gold-containing material is disposed between the adhesive layer and the glass layer so as to prevent ionic migration from the reflective layer through a terminal strip.
