Abstract: A film including a substrate, a base layer, and an adhesive layer in this order, in which the base layer includes a reaction cured product of a (meth)acrylic polymer and a curing agent, and the base layer has an elongation rate of 90% or more as measured by a tensile test at 25° C. and a speed of 100 mm/min and determined by the following formula, Elongation rate (%)=(elongation (mm) at break)×100/(distance (mm) between grippers before applying tension).

Abstract: The present invention relates to a film including at least a substrate and an antistatic layer, in which a ratio of a peeled area when a tape peeling test is performed under the following conditions after 300% uniaxial stretching at 25° C. is less than 5%, the tape peeling test is that: Cellotape® is pressure-bonded to a surface of the film on an antistatic layer side using a roller through 5 reciprocations with a load of 4 kg, and the Cellotape® is peeled off at a speed of 100 m/min in a direction of 180° with respect to the film within 5 minutes, thereby obtaining a ratio of a peeled area of the film to an area of an adhesive portion of the Cellotape®.
