Vehicle glazing with metal-based coating and colored edge region
A vehicle glazing includes a first pane and a second pane which are connected to one another via a thermoplastic intermediate layer which is sectionally colored, a metal-based functional layer which is deposited on an inner surface of the first pane facing the thermoplastic intermediate layer, on the inner surface of the first pane, a coating-free edge region which is free of metal-based functional layer and extends from a side edge of the first pane over at least 5 mm to at most 25 mm on the inner surface, wherein the thermoplastic intermediate layer includes a transparent region and a colored region, the colored region being arranged at least in the entire coating-free edge region.
1. A vehicle glazing comprising:
a first pane and a second pane which are connected to one another via a thermoplastic intermediate layer which is sectionally colored,
a metal-based functional layer which is deposited on an inner surface of the first pane facing the thermoplastic intermediate layer, and
a coating-free edge region on the inner surface of the first pane, which is free of metal-based functional layer and which extends from a side edge of the first pane over at least 5 mm to at most 25 mm on the inner surface, wherein
the thermoplastic intermediate layer comprises a transparent region and a colored region, the colored region being arranged at least in the entire coating-free edge region.
2. The vehicle glazing according to claim 1 , wherein the colored region extends beyond the coating-free edge region and extends from the side edge of the first pane to at most 150 mm.
3. The vehicle glazing according to claim 1 , wherein the colored region consists of a uniformly colored region and a variably colored region, the uniformly colored region directly adjoining the side edge.
4. The vehicle glazing according to claim 3 , wherein the uniformly colored region is arranged congruently with the coating-free edge region.
5. The vehicle glazing according to claim 1 , wherein the coating-free edge region extends from the side edge at least 5 mm to at most 20 mm.
6. The vehicle glazing according to claim 1 , wherein the vehicle glazing comprises a peripheral pane edge, and the colored region is arranged in sections along the peripheral pane edge.
7. The vehicle glazing according to claim 1 , wherein the vehicle glazing comprises a peripheral pane edge, and the coating-free edge region and the colored region extend as a frame along the entire peripheral pane edge.
8. The vehicle glazing according to claim 1 , wherein the first pane and the second pane do not comprise any covering print, at least in the colored region.
9. The vehicle glazing according to claim 1 , wherein the metal-based functional layer contains at least one metal layer, and is designed to reflect incident infrared light.
10. The vehicle glazing according to claim 1 , wherein the vehicle glazing is a motor vehicle pane, and the first pane is the outer pane, and the second pane is the inner pane of the vehicle glazing.
11. A method for producing a vehicle glazing according to claim 1 , comprising:
providing a first pane and a second pane,
applying a metal-based functional layer to a surface of the first pane provided as an inner surface,
removing the metal-based functional layer in an edge region extending from a side edge of the first pane over 5 mm to at most 25 mm,
providing a thermoplastic intermediate layer with a colored region which is at least as large as the coating-free edge region,
forming a stack from the first pane, the second pane and, in-between, the thermoplastic intermediate layer so that the inner surface of the first pane faces the thermoplastic intermediate layer, and the colored region is arranged congruently with the coating-free edge region, and
connecting the first pane, the second pane and the thermoplastic intermediate layer under the effect of heat, vacuum and/or pressure.
12. The method according to claim 11 , wherein the thermoplastic intermediate layer is provided with a colored region by co-extruding a melt flow with color pigment for the colored region and a melt flow without color pigment for the transparent region.
13. The method according to claim 11 , wherein the thermoplastic intermediate layer is provided with a colored region by coloring the surface of the thermoplastic intermediate layer in the colored region.
14. The method according to claim 11 , wherein the metal-based functional layer is removed in the coating-free edge region by mechanical delayering, laser delayering or removal of a masking layer applied during the application of the metal-based functional layer.
15. A method comprising providing a vehicle glazing according to claim 1 in a vehicle of transportation for traffic on land, in the air or in water.
16. The vehicle glazing according to claim 2 , wherein the colored region extends from the side edge of the first pane to at most 100 mm.
17. The vehicle glazing according to claim 5 , wherein the coating-free edge region extends from the side edge at least 6 mm to at most 15 mm.
18. The vehicle glazing according to claim 10 , wherein the motor vehicle pane is a side pane or roof pane of a motor vehicle.
19. The method according to claim 14 , wherein the metal-based functional layer is removed in the coating-free edge region by a grinding process.
20. The method according to claim 15 , wherein the vehicle glazing is a rear window, side pane and/or roof pane of the vehicle.
21. The vehicle glazing according to claim 1 , wherein the colored region is arranged at least in the entire coating-free edge region from the inner surface of the first pane to the inner surface of the second pane.
