Abstract:
The present invention aims to provide an interlayer film for a laminated glass which has a multilayer structure including two or more resin layers laminated together and can prevent optical distortion even at high temperatures, a laminated glass including the interlayer film for a laminated glass, and a method of producing the interlayer film for a laminated glass. The present invention relates to an interlayer film for a laminated glass, the interlayer film including: two or more resin layers laminated together, one resin layer having a surface with a ratio (Rz/Sm) of a ten-point average roughness Rz (µm) to an average interval Sm (µm) of projections and recesses of 0.0018 or less as measured in conformity with JIS B-0601(1994) in the following manner: a laminated glass is produced using two clear glass sheets conforming to JIS R3202(1996) and the interlayer film; the interlayer film is peeled away from the clear glass sheets after the laminated glass is cooled with liquid nitrogen; the one resin layer is peeled away from another resin layer that is in direct contact with the one resin layer; and the Rz and Sm of the surface of the one resin layer on the side having been in contact with the other resin layer are measured.
