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;
wherein said front substrate has a perimeter band disposed along a perimeter region of said second surface;
wherein said perimeter band comprises (i) a layer of chromium established at said second surface, (ii) a first layer of nickel chromium established at said layer of chromium, (iii) a layer of silver or silver alloy established at said first layer of nickel chromium, and (iv) a second layer of nickel chromium established at said layer of silver or silver alloy;
a rear substrate having a third surface and a fourth surface, wherein said third surface has a conductive reflector 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; and
wherein said third surface conductive reflector 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 reflective layer comprises one of ruthenium, rhodium, platinum and palladium.

Abstract
A variable reflectance vehicular electro-optic rearview mirror reflective element assembly includes a front substrate and a rear substrate with a perimeter seal disposed therebetween. The front substrate has a first surface and a second surface opposite the first surface, with the second surface having 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 reflector coating disposed thereat. The reflector coating may include a plurality of layers having first and second layers of nickel chromium. The front substrate may have a perimeter band disposed along a perimeter region of the second surface. The perimeter band may include a plurality of layers having first and second layers of nickel chromium.
