Title:

REINFORCING FILM, OPTICAL MEMBER AND ELECTRONIC MEMBER

Document Type and Number:

Japanese Patent JP2022030291

Kind Code:

A

Abstract:

To provide a reinforcing film that shows light peelability at first after stuck to an adherend and allows, thereafter, the adhesion to be increased greatly, and has flex recoverability and flex holding power.SOLUTION: A reinforcing film 100 has an adhesive layer 21 having: a polymer (B) that includes a monomer unit having a polyorganosiloxane skeleton and a (meth)acrylic monomer unit ; and a polymer (A), the adhesive layer 21 having a surface elastic modulus of 1-20 kPa at 23°C. The adhesive layer 21 has a bulk elastic modulus G' of 10-200 kPa at 23°C and a bulk elastic modulus G' of 5-100 kPa at 80°C, and has a tanδ of 0.10-0.60 at 80°C.SELECTED DRAWING: Figure 1
