First claim

Opening claim text (preview).

The invention claimed is: 1. A laminated glazing for reducing or preventing bird collision, the laminated glazing comprising: a first glass sheet, a second glass sheet, a first interlayer, and a second interlayer, wherein at least one surface of the first interlayer is provided with a bird protection pattern facing the second interlayer, the first interlayer comprises an ionomer, and a yellowness index db of the laminated glazing in areas not comprising the bird protection pattern is less than 2 as determined by transmission of the laminated glazing 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 interlayer. 3. The laminated glazing according to claim 1 , wherein the bird protection pattern has a transparency for light ranging 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 laminated glazing in the areas not comprising the bird protection pattern has a transparency for light ranging from 380 to 750 nm of more than 50% measured according to JIS R 3106 and comprises a UV absorber or a UV reflection agent. 5. The laminated glazing according to claim 1 , wherein the ionomer is a sodium-neutralized ethylene-α,β-unsaturated carboxylic acid copolymer. 6. The laminated glazing according to claim 1 , wherein the bird protection pattern is a dot pattern. 7. The laminated glazing according to claim 1 , wherein the first interlayer comprises a dialkoxysilane. 8. The laminated glazing according to claim 1 , wherein the second interlayer comprises an ionomer. 9. The laminated glazing according to claim 8 , wherein the ionomer contained in the first interlayer and the second interlayer is a sodium-neutralized ethylene-α,β-unsaturated carboxylic acid copolymer. 10. The laminated glazing according to claim 1 , wherein at least one of the first interlayer and the second interlayer comprises no plasticizer. 11. 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.
