Abstract

The invention relates to laminated glass comprising first ( 11 ) and second ( 12 ) sheets of glass laminated using at least one thermoplastic interlayer ( 20 ). According to the invention, such glass comprises at least one thermoplastic interlayer ( 20 ) including a zone that is opaque at visible wavelengths ( 21 ).

First claim

1 . A laminated glazing comprising a first glass sheet and a second glass sheet laminated by at least one thermoplastic interlayer, wherein the at least one thermoplastic interlayer comprises a zone that is opaque to visible wavelength radiation.

2 . The laminated glazing according to claim 1 , wherein the opaque zone extends over a periphery of at least one of the first and second glass sheets.

3 . The laminated glazing according to claim 1 , wherein the opaque zone extends over a periphery of an internal face 2 of the first glass sheet.

4 . The laminated glazing according to claim 1 , wherein the at least one thermoplastic interlayer is formed by an opaque zone, the light transmission of which is less than 5% of incident light.

5 . The laminated glazing according to claim 1 , wherein the at least one thermoplastic interlayer is formed by an opaque zone, the light transmission of which is 0% of incident light.

6 . The laminated glazing according to claim 1 , wherein the at least one first thermoplastic interlayer is positioned substantially on a surface of the glazing.

7 . The laminated glazing according to claim 1 , wherein the at least one first thermoplastic interlayer is formed from an opaque frame positioned around a nonopaque zone.

8 . The laminated glazing according to claim 1 , wherein the opaque zone extends over lower and upper edges of the laminated glazing.

9 . The laminated glazing according to claim 1 , wherein the at least one first thermoplastic interlayer is a sheet comprising polyvinyl butyral or ethylene-vinyl acetate.

10 . The laminated glazing according to claim 1 , wherein the opaque zone is obtained by a bulk coloring of a periphery of the interlayer.

11 . The laminated glazing according to claim 1 , further comprising, on a face 4 , an enamel strip comprising dots.

12 . The laminated glazing according to claim 11 , wherein the enamel strip overlaps the opaque zone over at least a portion.

13 . The laminated glazing according to claim 11 , wherein the enamel strip overlaps the opaque zone over a distance of between 4 and 30 mm.

14 . The laminated glazing according to claim 1 , which is a windshield for a motor vehicle.
