Abstract

A mirror pane for a back-surface mirror includes a carrier plate including a front side defining a first main surface and a back side defining a second main surface, a reflective coating disposed upon the second main surface, and a transparent, scratch-resistant protective coating disposed upon and covering the first main surface. The protective coating includes a nano-composite material.

Claims

1. A mirror pane for a back surface mirror, in particular for rearview mirrors in motor vehicles with a front side (2) and a back side (4), a transparent carrier plate (6), a reflective coating (20) on the back side (4) of the carrier plate (6), characterized by a transparent, scratch-free, dirt and water repellent protective coating (28) applied as the outermost coating on the front side (2) of the carrier plate (6).

2. A mirror pane in accord with claim 1, therein characterized, in that the protective coating (28) covers the interstitial border zone between the reflectant coating (20) and the carrier plate (6) as well as the side edges (10, 12, 13).

3. A mirror pane in accord with one of the foregoing claims, therein characterized, in that the protective coating (28) is comprised of an inorganic-organic nanocomposite gradient coating with fluoridized organic side chains.

4. A mirror pane in accord with one of the foregoing claims, therein characterized, in that the carrier plate (6) is comprised of glass.

5. A mirror pane in accord with one of the foregoing claims, therein characterized in that the carrier plate (6) is comprised of plastic.

6. A mirror pane in accord with one of the foregoing claims, therein characterized in that the reflection coating (20) is comprised of silver.

7. A rearview mirror for motor vehicles, in particular for commercial vehicles, with a swingable housing and an advantageously, pivotably secured mirror pane mirror, characterized therein by a mirror pane according to one of the foregoing claims.
