PROBLEM TO BE SOLVED: To provide a laminate for decorative molding which can exhibit sufficient stretchability and shows little reduction in a haze before and after stretching.SOLUTION: There is provided a laminate 1 for decorative molding including a surface protective layer 2 having a photocurable resin on the outermost surface, where a haze of the surface protective layer 2 is 10% or more, elongation at break at 120°C in a first direction of the laminate 1 for decorative molding is more than 50%, elongation at break at 120°C in a second direction orthogonal to the first direction is more than 50%, and when the haze of the surface protective layer 2 before the laminate 1 for decorative molding is stretched is represented by P and the haze of the surface protective layer after the laminate 1 for decorative molding has been stretched in the first direction or the second direction by 50% is represented by Q, a haze reduction rate represented by (P-Q/P)×100 is 40% or less.SELECTED DRAWING: Figure 1
【課題】十分な延伸性を発揮でき、かつ延伸前後のヘイズの低下が少ない加飾成形用積層体を提供する。【解決手段】最表面に光硬化樹脂を有する表面保護層2を含む加飾成形用積層体1であって、表面保護層2のヘイズは10%以上であり、加飾成形用積層体1の第1の方向の120℃における破断伸度は50%より大きく、かつ第1の方向と直交する第2の方向の120℃における破断伸度は50%より大きく、加飾成形用積層体1を延伸する前の表面保護層2のヘイズをPとし、加飾成形用積層体1を第1の方向または第2の方向に50%延伸した後の表面保護層のヘイズをQとした場合、(P−Q/P)×100で表されるヘイズ低下率が40%以下である、加飾成形用積層体1。【選択図】図1
