Abstract

Official abstract text for this publication.

It is an object of the present invention to provide an interlayer film for a laminated glass excellent in a sound-insulating property, which is preferably usable for a head up display and the like wherein a driver can look at the front view and an instrument display simultaneously without requiring to look down, and to provide a laminated glass. The present invention is directed to interlayer film for a laminated glass, which comprises at least a pair of protection layers and a sound-insulating layer sandwiched between the pair of the protection layers, and which has a wedge shape as a cross-sectional shape, a wedge angle e of 0.1 to 0.7 mrad, the maximum thickness of 2000 μm or thinner, and the minimum thickness of 400 μm or thicker, the minimum thickness of the sound-insulating layer being 20 μm or thicker.

First claim

Opening claim text (preview).

1 . An interlayer film for a laminated glass, which comprises at least a pair of protection layers and a sound-insulating layer sandwiched between the pair of the protection layers, and which has a wedge shape as a cross-sectional shape, a wedge angle θ of 0.1 to 0.7 mrad, the maximum thickness of 2000 pm or thinner, and the minimum thickness of 400 μm or thicker, the minimum thickness of the sound-insulating layer being 20 μm or thicker. 2 . The interlayer film for a laminated glass according to claim 1 , which further comprises a shape assisting layer laminated on at least one layer of the pair of the protection layers. 3 . The interlayer film for a laminated glass according to claim 1 , wherein the protection layer, and/or the sound-insulating layer contain a heat-insulating agent 4 . The interlayer film for a laminated glass according to claim 2 , wherein the shape assisting layer contains a heat-insulating agent. 5 . A laminated glass, which is obtained by using the interlayer film for a laminated glass according to claim 1 . 6 . A laminated glass, which is obtained by using the interlayer film for a laminated glass according to claim 2 . 7 . A laminated glass, which is obtained by using the interlayer film for a laminated glass according to claim 3 . 8 . A laminated glass, which is obtained by using the interlayer film for a laminated glass according to claim 4 .
