Mirror reflective element
First Claim
1. A variable reflectance vehicular electro-optic rearview mirror reflective element assembly comprising:
- a front substrate having a first surface that generally faces a driver of a vehicle equipped with a mirror assembly that incorporates said rearview mirror reflective element assembly;
said front substrate having a second surface opposite said first surface, wherein said second surface of said front substrate has a transparent electrically conductive coating disposed thereat;
a rear substrate having a third surface and a fourth surface, wherein said third surface has a conductive coating disposed thereat;
a perimeter seal disposed between said front and rear substrates, said perimeter seal spacing said front and rear substrates apart and forming an interpane cavity therebetween;
wherein said third surface conductive coating comprises a plurality of layers, and wherein said plurality of layers comprises (i) a first layer of nickel chromium, (ii) a silver or silver alloy layer established at said first layer of nickel chromium, (iii) a second layer of nickel chromium established at said silver or silver alloy layer, and (iv) a reflective layer established at said second layer of nickel chromium;
wherein said plurality of layers are disposed over a perimeter region of said fourth surface of said rear substrate; and
wherein said plurality of layers has a sheet resistance of less than about 0.5 ohms per square.

Abstract
A variable reflectance vehicular electro-optic rearview mirror reflective element assembly includes a front substrate and a rear substrate and a perimeter seal disposed therebetween. The front substrate has a first surface and a second surface that has a transparent electrically conductive coating disposed thereat. The rear substrate has a third surface and a fourth surface, with the third surface having a conductive coating disposed thereat. The perimeter seal spaces the front and rear substrates apart and forms an interpane cavity therebetween. The third surface conductive coating includes a plurality of layers, which includes a first layer of nickel chromium. The first layer of nickel chromium is overcoated with a silver or silver alloy layer, and the silver or silver alloy layer is overcoated with a second layer of nickel chromium, and the second layer of nickel chromium is overcoated with a reflective layer.
