Abstract:
The present invention provides a film for reinforcement, which exhibits easy separability in the initial stage after bonding to an adherend, while being capable of greatly increasing the adhesive force thereafter, and which exhibits recovery from bending and bending retainability. This film for reinforcement is provided with an adhesive layer. The adhesive layer contains a polymer (A) and a polymer (B). The polymer (B) contains a monomer unit that has a polyorganosiloxane skeleton and a (meth)acrylic monomer unit. The adhesive layer has a surface elastic modulus of from 1 to 20 kPa at 23°C. In addition, the polymer (B) has a glass transition temperature TB of from -20°C to 5°C.
