Patent ID: 7156533

Claim:
A rearview mirror for motor vehicles moveable between a perpendicular viewing angle to a tilted position 45° from the perpendicular viewing angle, comprising: a layer substrate; and a coating applied to the layer substrate, the coating including a reflective mirror coating and an intermediate layer disposed between the reflective mirror coating and the layer substrate, wherein a magnitude of a parameter for coloring C=√{square root over (a 0 2 +b 0 2 )} is greater than 5 wherein a 0 represents a first color coordinate value and b 0 represents a second color coordinate value at a perpendicular light incidence according to CIE and a color change ΔE resulting from a tilting of the rearview mirror to the tilted position as a function of a magnitude of the first color coordinate value a 0 is given by: Δ E≦ ½·(| a 0 |−8) when a 0 ≦−20; Δ E≦ 6 when −20≦ a 0 ≦0; or Δ E≦ ½·( a 0 +12), when a 0 ≧0.
