发明名称 INTERMEDIATE FILM FOR LAMINATED GLASS AND LAMINATED GLASS
摘要 Provided is an intermediate film for laminated glass that can obtain a laminated glass having a gradation pattern in which color unevenness is suppressed. The intermediate film for laminated glass is provided with: a first resin layer containing a thermoplastic resin and a plasticizer; and a second resin layer containing a thermoplastic resin, a plasticizer, and inorganic particles. The first resin layer is disposed at the first surface side of the second resin layer. When producing laminated glass, there is a gradation section that is a region in which the parallel light transmittance is 30-60% exclusive and the thickness of the second resin layer continuously decreases in a direction perpendicular to the thickness direction of the intermediate film. The complex viscosity of the second resin layer at 200°C is a multiple of 0.7-2 inclusive of the complex viscosity of the first resin layer at 200°C.
