发明名称 INTERMEDIATE FILM FOR LAMINATED GLASS AND LAMINATED GLASS
摘要 There is provided an interlayer film for laminated glass with which laminated glass having a gradation pattern with suppressed color irregularity can be prepared. The interlayer film for laminated glass according to the present invention includes 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, and the first resin layer being arranged on a first surface side of the second resin layer, wherein a gradation part being a region where the parallel light transmittance is greater than 30% and less than 60% and being a region where the thickness of the second resin layer is continuously decreased in the direction orthogonal to the thickness direction of the interlayer film at the time of preparing the laminated glass exists, and the complex viscosity at 200°C of the second resin layer is greater than or equal to 0.7 times and less than or equal to 2 times the complex viscosity at 200°C of the first resin layer.
