Zusammenfassung:Provided is a laminated film having excellent moldability and releasability from a mold. A laminated film provided with a transparent support substrate and a coating layer disposed on at least one main surface of the transparent support substrate, the coating layer comprising an active energy ray-curable resin composition, the thickness of the coating layer exceeding 2 [mu] m, the indentation hardness HB100 of the coating layer as determined by a nanoindentation method at an indentation depth of 100 nm being 0.30-0.65 GPa, and the thickness of the coating layer exceeding 2 [mu] m. The press-in hardness (HB 2000) of the coating layer as measured by a nanoindentation method at a press-in depth of 2000 nm is 0.15 GPa or more and 0.35 GPa or less, and the press-in hardness (HB 2000) is less than the press-in hardness (HB 100). 本发明提供赋形性和从模具的脱模性优异的层叠膜。一种层叠膜,其具备透明支撑基材和配置于上述透明支撑基材的至少一个主面的涂层,上述涂层包含活性能量射线固化性树脂组合物,上述涂层的厚度超过2μm,上述涂层在压入深度100nm的基于纳米压痕法的压入硬度HB100为0.30GPa以上且0.65GPa以下,上述涂层在压入深度2000nm的基于纳米压痕法的压入硬度HB2000为0.15GP
