    摘要: Provided is a novel surface protective film that can express sufficiently high wettability even when no plasticizer is used, can prevent the formation of a stop mark, and is excellent in reworkability. The surface protective film is a surface protective film, including: a base material layer; and a pressure-sensitive adhesive layer, in which: a gel fraction of the pressure-sensitive adhesive layer is 70% or more; and a first wetting rate with respect to an acrylic plate in a surface of the pressure-sensitive adhesive layer, which is brought into contact with an adherend, is 5.0 cm 2 /sec or more.

    摘要: Provided is a novel surface protective film that can express sufficiently high antistatic property even without the use of any antistatic agent, can express sufficiently high wettability even without the use of any plasticizer, and is excellent in reworkability (light peelability). The surface protective film includes: a base material layer; and a pressure-sensitive adhesive layer, in which: the pressure-sensitive adhesive layer has a peeling electrification voltage of 0.7 kV or less; and a first wetting rate with respect to an acrylic plate in a surface of the pressure-sensitive adhesive layer, which is brought into contact with an adherend, is 5.0 cm 2 /sec or more.
