摘要： The present invention aims to provide an interlayer film for a laminated glass, which can exhibit high deaeration properties during preliminary pressure bonding and enables production of a highly transparent laminated glass, a roll, a laminated glass, a method for producing the interlayer film for a laminated glass, and a method for producing the roll. The present invention relates to an interlayer film for a laminated glass, having a large number of recesses and a large number of projections on at least one surface, the interlayer film for a laminated glass having a thickness with a difference between a maximum thickness and a minimum thickness of less than 40 µm at each of a central portion, one end portion, and an other end portion in a width direction that is orthogonal, in the same plane, to a machine direction of the film in production of the interlayer film for a laminated glass, the thickness being measured along 3 m in the machine direction of the film in production of the interlayer film for a laminated glass at the central portion, the one end portion, and the other end portion in the width direction.

摘要： 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.

摘要： The present invention aims to provide an interlayer film for laminated glass which has a laminated structure including a plastic layer with a high Young's modulus and a resin layer, which is excellent in impact resistance and penetration resistance, which has high adhesiveness between the plastic layer and the resin layer, and which prevents blocking of the resin layer, and a laminated glass including the interlayer film for laminated glass. The present invention relates to an interlayer film for laminated glass, having a multilayer structure including: a plastic layer with a Young's modulus of 1 GPa or more; and a first resin layer on a first surface of the plastic layer, the first resin layer having a glossiness of 10 to 40 on the surface on the side to be in contact with the plastic layer.
