Title:
INTERLAYER FILM FOR LAMINATED GLASS AND METHOD FOR MANUFACTURING SAME AND LAMINATED GLASS AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2023/200014
Kind Code:
A1
Abstract:
Provided is an interlayer film for a laminated glass capable of suppressing the occurrence of a double image and unevenness in heat shielding performance. An interlayer film for a laminated glass according to the present invention comprises a region having a partial wedge angle of 0.05 mrad or more in a length of 400 mm in a direction connecting one end and the other end of the interlayer film, the interlayer film including a heat shielding layer containing a heat shielding substance and having a glass transition temperature of 15°C or higher. When the distance between the one end and the other end of the interlayer film is defined as X, a thickness of the interlayer film at an arbitrary position (1) of the interlayer film within a region from 0.1X to 0.9X measured from the one end toward the other end, a thickness of the interlayer film at a position (2) having a thickness of the interlayer film smaller than the thickness of the interlayer film at the position (1) by 25 μm or more, visible light transmittance at the position (1) of a laminated glass including the interlayer film, and solar transmittance at the position (2) of the laminated glass including the interlayer film satisfy a specific relationship.
