Embodiment 1～9、17 and comparative example 1、3

[0328] First laminated glass part:

[0329] Transparent glass having thicknesses and wedge angles shown in Tables 1, 2, and 4 below was prepared. It should be noted that in the case of a wedge angle of 0 mrad, it means that the shape is a rectangle rather than a wedge.

[0330] First resin layer:

[0331] The following components were prepared and sufficiently kneaded with a mixing roll to obtain a composition for forming the first resin layer.

[0332] Polyvinyl acetal resin (average degree of polymerization 1700, hydroxyl content 30.5 mol%, degree of acetylation 1 mol%, degree of acetalization 68.5 mol%) 100 parts by weight

Abstract

Provided is a laminated glass which has excellent thermal insulation properties, suppresses the occurrence of multiple images in a head-up display, and can enhance the display of images. A laminated glass according to the present invention is provided with a first laminated glass member, a first resin layer, an infrared ray reflection layer, and a second laminated glass member, wherein a laminateof the infrared ray reflection layer and the second laminated glass member is thin or wedge-shaped. Alternatively, the laminated glass according to the present invention is provided with the first laminated glass member, the first resin layer, the infrared ray reflection layer, a second resin layer, and the second laminated glass member, wherein a laminate of the infrared ray reflection layer andthe second resin layer is thin or wedge-shaped.

Description

technical field [0001] The invention relates to an interlayer film for laminated glass used in laminated glass. The invention relates to a laminated glass as a head-up display. In addition, the present invention relates to a method for installing the laminated glass. Background technique [0002] In general, even when laminated glass is damaged by external impact, the amount of glass shards scattered is small and it is excellent in safety. Therefore, the laminated glass is widely used in automobiles, rail vehicles, aircraft, ships, buildings, and the like. The laminated glass is manufactured by interposing an interlayer film for laminated glass between a pair of glass plates. Such laminated glass used for openings of vehicles and buildings requires high heat insulation. [0003] In order to improve heat insulation, an interlayer film provided with an infrared reflection layer may be used. Patent Document 1 below discloses an interlayer film including an infrared reflect...
