PROBLEM TO BE SOLVED: To solve the problems that rigidity of a laminate is low and is easily deflected when an external stress is applied, and to provide a transparent resin laminate which has more excellent rigidity than those of transparent resin laminates being used hitherto and has excellent impact resistance and transparency.SOLUTION: There is provided a transparent resin laminate which is formed of at least two transparent resin sheets and an intermediate layer, where a resin forming the intermediate layer contains thermoplastic polyurethane, a layer thickness of the transparent resin sheet is in a range of 6.5 mm or more and 100 mm or less, and a layer thickness of the intermediate layer is in a range of 0.4 mm or more and 8 mm or less.SELECTED DRAWING: Figure 1

    【課題】従来技術では、積層体の剛性が低く、外部応力がかかると撓みやすい等の問題があった。本発明は、透明樹脂積層体に関し、これまでに使用されている透明樹脂積層体よりも優れた剛性を有し、且つ耐衝撃性、透明性に優れる透明樹脂積層体を提供することを目的とする。【解決手段】本発明は、少なくとも2つの透明樹脂シートおよび中間層からなり、中間層を形成する樹脂が、熱可塑性ポリウレタンを含み、前記透明樹脂シートの層厚が6.5mm以上100mm以下の範囲にあり、前記中間層の層厚が0.4mm以上8mm以下の範囲にあることを特徴とする透明樹脂積層体を提供するものである。【選択図】図1
