Abstract
Official abstract text for this publication.
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
Opening claim text (preview).
The invention claimed is: 1. A laminated glazing comprising: a first glass sheet and a second glass sheet laminated by at least one thermoplastic interlayer; and an enamel strip on an external face 4 of the second glass sheet, 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 thermoplastic interlayer is positioned substantially on a surface of the glazing. 7. The laminated glazing according to claim 1 , wherein the at least one 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 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 , wherein the enamel strip comprises 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.
