INTERMEDIATE FILM FOR LAMINATED GLASS AND LAMINATED GLASS
PROBLEM TO BE SOLVED: To provide an intermediate film for laminated glass capable of obtaining the laminated glass having a gradation pattern in which color unevenness is suppressed.SOLUTION: An intermediate film for laminated glass has a first resin layer containing thermoplastic resin and a plasticizer and a second resin layer containing the thermoplastic resin, the plasticizer and an inorganic particle. the first resin layer is arranged at a first surface side of the second resin layer, a gradation part, which is an area that parallel light transmittance is over 30% and below 60% when the laminated glass is manufactured, and a thickness of the second resin is continuously reduced in a direction orthogonal to a thickness direction of the intermediate film, exists, and complex viscosity of the second resin layer at 200°C is 0.7 times or more and 2 times or less as complex viscosity of the first resin layer at 200°C.SELECTED DRAWING: Figure 1
【課題】色むらが抑えられたグラデーション模様を有する合わせガラスを得ることができる合わせガラス用中間膜を提供する。【解決手段】本発明に係る合わせガラス用中間膜は、熱可塑性樹脂及び可塑剤を含有する第１の樹脂層と、熱可塑性樹脂、可塑剤及び無機粒子を含有する第２の樹脂層とを備え、前記第２の樹脂層の第１の表面側に、前記第１の樹脂層が配置されており、合わせガラスを作製した際に、平行光透過率が３０％を超え、６０％未満である領域であってかつ上記第２の樹脂層の厚みが、中間膜の厚み方向と直交する方向に連続的に減少している領域であるグラデーション部が存在し、上記第２の樹脂層の２００℃における複素粘度が、前記第１の樹脂層の２００℃における複素粘度の０．７倍以上２倍以下である。【選択図】図１
