INTERLAYER FOR LAMINATED GLASS, AND LAMINATED GLASS

Title:

INTERLAYER FOR LAMINATED GLASS, AND LAMINATED GLASS

Document Type and Number:

WIPO Patent Application WO/2017/057624

Kind Code:

A1

Abstract:

An interlayer for laminated glass is provided which, when used to obtain a laminated glass, is capable of inhibiting the persistence of air bubbles between laminated glass members and the interlayer. An interlayer for laminated glass according to the present invention includes a thermoplastic resin, and is provided with one end, and another end which is located at the opposite side to the one end, and which has a greater thickness than the one end. Each of three values, namely the value of the ten-point average roughness Rz of the surface at a position 50 mm from the one end towards the other end, the value of the ten-point average roughness Rz of the surface at a position in the centre between the one end and the other end, and the value of the ten-point average roughness Rz of the surface at a position 50 mm from the other end towards the one end, is at least 20 µm. The value obtained by subtracting the smallest value among the three values from the greatest value among the three values is at least 3 µm, but not more than 9 µm.
