Document Type and Number:
WIPO Patent Application WO/2017/057334
Kind Code:
A1
Abstract:
Provided is an interlayer for laminated glass, capable of considerably suppressing the occurrence of double images in the laminated glass. This interlayer for laminated glass has one end and another end on the opposite side to the one end. The thickness of the other end is greater than the thickness of the one end. The interlayer has a display-corresponding area corresponding to a display area for a head-up display. When locations are selected at 2 mm intervals, having a position at 4 cm towards the other end from an end section on the one end side of the display-corresponding area as the starting point and a position at 4 cm towards the one end from an end section on the other end side of the display-corresponding area as the end point, and the amount of change in thickness is measured for each 80 mm area in the direction connecting the one end and the other end and having each location as the center point of therefor, the absolute value for the difference between the maximum change in thickness and the minimum change in thickness is no more than 32 µm.
