(57) Abstract:
(EN): Provided is a surface protective film including a hard coat layer, a substrate layer, an adhesive layer in this order, wherein the surface protective film can sufficiently follow repeated curves. This surface protective film according to the present invention includes a hard coat layer, a substrate layer, and an adhesive layer in this order, wherein the Young's modulus of a laminate of the hard coat layer and the substrate layer is 5 MPa to 1,800 MPa at 23ºC, and Tg measured by the DSC of an adhesive constituting the adhesive layer is no greater than 0ºC.
(FR): L'invention concerne un film de protection de surface comprenant une couche de revêtement dur, une couche de substrat, une couche adhésive dans cet ordre, le film de protection de surface pouvant suivre de façon suffisante une succession de courbes. Le film de protection de surface selon la présente invention comprend une couche de revêtement dur, une couche de substrat et une couche adhésive dans cet ordre, le module de Young d'un stratifié de la couche de revêtement dur et de la couche de substrat étant de 5 MPa à 1 800 MPa à 23 °C, et la Tg mesurée par le DSC d'un adhésif constituant la couche adhésive n'étant pas supérieure à 0 °C.
(JA): ハードコート層と基材層と粘着剤層をこの順に含む表面保護フィルムであって、繰り返される屈曲に十分に追従できる表面保護フィルムを提供する。 本発明の表面保護フィルムは、ハードコート層と基材層と粘着剤層をこの順に含む表面保護フィルムであって、該ハードコート層と該基材層の積層体の23℃におけるヤング率が5MPa~1800MPaであり、該粘着剤層を構成する粘着剤のDSCによって測定したTgが0℃以下である。
