<p>The present invention is to provide a composite film having transparency, strength, elongation, and flexibility. The composite film contains: a urethane polymer formed from a polyol and a polyisocyanate; and an acrylic polymer obtained by photopolymerization of one or more (meth)acrylic monomers, in which total light transmittance of the composite film is 93.0% or more in terms of a thickness of 100 µm, breaking strength (23°C) of the composite film is 3.0 MPa or more to 75 MPa or less, breaking elongation ratio (23°C) is 150% or more to 1,000% or less, and 20% modulus (23°C) is 0.1 MPa or more to 7.5 MPa or less.</p> |
