Hydrophilic mirror and method of producing the same
First Claim
1. A hydrophilic mirror comprising a glass substrate having on one of the two main surface sides thereof (1) a layer having a refractive index n1 at 550 nm, (2) a layer having a refractive index n2 at 550 nm, (3) a tin oxide layer having a refractive index n3 at 550 nm, and (4) an overcoat in this order, the refractive indices n1, n2, and n3 satisfying the relationship:
- n1≧
n3>
n2, and having a reflectance of 70% or more of visible light incident on the coated side, wherein said overcoat is of at least one of silicon oxide, aluminum oxide, zirconium oxide, cerium oxide, and titanium oxide.
