Title:
合わせガラス用中間膜及び合わせガラス
Document Type and Number:
Japanese Patent JP7104019
Kind Code:
B2
Abstract:
Provided is an interlayer film for laminated glass capable of suppressing double images, and making the moisture resistance of the laminated glass exposed to high temperature and high humidity uniform at one end and the other end of the interlayer film. The interlayer film for laminated glass according to the present invention is an interlayer film for laminated glass, being wedge-like shaped and containing an amphiphile or a surfactant, and when a high temperature and high humidity test for laminated glass is executed, a whitening distance at the one end and the other end of the interlayer film is 15 mm or less, and when a whitening distance at the one end of the interlayer film is more than 0 mm, a value of (whitening distance at the other end of the interlayer film × thickness of the other end of the interlayer film)/(whitening distance at the one end of the interlayer film × thickness of the one end of the interlayer film) is 0.70 or more.
