Abstract
Official abstract text for this publication.
The invention is directed to laminated glazing comprising two glass sheets laminated by means of at least two thermoplastic interlayers wherein at least one surface of one of the interlayers is provided with a bird protection pattern in between the two thermoplastic interlayers and wherein at least one thermoplastic interlayer comprises a polyvinyl acetal.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A laminated glazing, comprising: at least two glass sheets; and at least a first and a second thermoplastic interlayer; wherein: at least one surface of the first thermoplastic interlayer comprises a bird protection pattern facing the second thermoplastic interlayer; the first thermoplastic interlayer comprises a polyvinyl acetal; the first and the second thermoplastic interlayer each contain at least 26.0% by weight plasticizer; the thickness of the first and the second thermoplastic interlayer is independently 450-2500 μm; and a yellowness index db of the laminated glazing in areas not comprising the bird protection pattern is less than 1.0 as determined by transmission of a film according to EN 410 at 430 nm on a ColorQuest XE in the Hunterlab 2°/C setting. 2 . The laminated glazing according to claim 1 wherein the bird protection pattern is printed or coated onto the at least one surface of the first thermoplastic interlayer. 3 . The laminated glazing according to claim 1 wherein the bird protection pattern has a transparency for light in a range from 380 to 750 nm of less than 5% measured according to JIS R 3106. 4 . The laminated glazing according to claim 1 wherein the bird protection pattern comprises a plurality of separate elements. 5 . The laminated glazing according to claim 4 wherein the separate elements have a main dimension of 1 mm to 10 mm. 6 . The laminated glazing according to claim 4 wherein the bird protection pattern is a dot pattern. 7 . The laminated glazing according to claim 1 wherein the second thermoplastic interlayer comprises a polyvinyl acetal. 8 . The laminated glazing according to claim 1 wherein at least one selected from the group consisting of the first thermoplastic interlayer and the second thermoplastic interlayer comprises a polyvinyl butyral (PVB). 9 . The laminated glazing according to claim 1 , wherein the first and the second thermoplastic interlayer each contain 26.0-36.0% by weight plasticizer. 10 . The laminated glazing according to claim 1 , wherein the first and the second thermoplastic interlayer each contain 26.0-30.0% by weight plasticizer. 11 . The laminated glazing according to claim 1 , wherein the thickness of the first and the second thermoplastic interlayer is independently 600-1000 μm. 12 . The laminated glazing according to claim 10 , wherein the thickness of the first and the second thermoplastic interlayer is independently 600-1000 μm. 13 . The laminated glazing according to claim 1 , wherein the thickness of the first and the second thermoplastic interlayer is independently 700-900 μm. 14 . The laminated glazing according to claim 10 , wherein the thickness of the first and the second thermoplastic interlayer is independently 700-900 μm. 15 . A glass window comprising: the laminated glazing according to claim 1 ; and a third glass sheet separated by air from the first glass sheet or the second glass sheet.
