Title:

INTERLAYER FILM FOR LAMINATED GLASS, ROLL, AND LAMINATED GLASS

Document Type and Number:

WIPO Patent Application WO/2020/250939

Kind Code:

A1

Abstract:

An interlayer film for laminated glass is provided which can suppress transmitted double images in the laminated glass.　This interlayer film for laminated glass comprises a first edge and a second edge opposite of the first edge, the thickness of the second edge being greater than the thickness of the first edge. When the slope of an approximation straight line A and the maximum value of the absolute value of the deviation of the partial wedge angle are calculated on the basis of a formula of the specific approximation straight line A and a calculation of the deviation of a partial wedge angle, in at least in one interval A, the slope of the approximation straight line A is less than or equal to -0.05 mrad/m, and the maximum value of the absolute value of the deviation of the partial wedge angle is less than or equal to 0.2 mrad/m.
