Abstract: The laminated glass of the present invention has a T/R rate (A) of larger than 1, the T/R rate (A) being calculated from the following formula (1): T/R rate (A)=log 10(TA/100)/log 10(RA/100)  (1) wherein an average transmittance at a wavelength of 900 to 1300 nm through one face is represented by TA, and a maximum reflectance at a wavelength of 900 to 1300 nm at an incident angle of 60° on the other face is represented by RA.

Abstract: The present invention aims to provide an interlayer film for a laminated glass that adheres sufficiently to glass at peripheral portions of the glass to prevent occurrence of a sealing failure at the peripheral portions and also to contribute to improved production efficiency of laminated glass in production of laminated glass, even when having a thickness at the thickest portion of 850 μm or more, and a laminated glass produced using the interlayer film for a laminated glass. Provided is an interlayer film for a laminated glass having a large number of recesses on at least one surface, the interlayer film for a laminated glass having a thickness T (μm) measured in conformity with JIS K-6732 (1996) and a maximum height roughness Ry (μm) measured in conformity with JIS B-0601 (1994) at a thickest portion, the thickness T and the maximum height roughness Ry satisfying the following expressions (1) and (1′): Ry≤0.0195×T+33.2  (1), T≥850  (1′).

Abstract: The present invention aims to provide an embossed thermoplastic resin sheet that is capable of enhancing deaeration during production of laminated glass and suppressing optical distortion of the resulting laminated glass to improve the visibility when used as an interlayer film for laminated glass. The present invention also relates to an engraved roll used for production of the embossed thermoplastic resin sheet, a production method of the engraved roll, an interlayer film for laminated glass including the embossed thermoplastic resin sheet, and a laminated glass. The present invention relates to an embossed thermoplastic resin sheet having a large number of recesses and a large number of projections on at least one surface, the recesses each having a groove shape with a continuous bottom and being regularly arranged side by side in parallel with one another, the thermoplastic resin sheet having not more than three defects of the projections per mm2 on the surface.

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.
