Document Type and Number:
WIPO Patent Application WO/2022/030307
Kind Code:
A1
Abstract:
Provided is a reinforcing film that exhibits light peelability at the initial stage of attachment to an adherend, can have greatly increased adhesive strength thereafter, and has bending recovery and bending holding power. The reinforcing film comprises an adhesive layer. The adhesive layer contains a polymer (A) and a polymer (B). The polymer (B) contains a monomer unit having a polyorganosiloxane skeleton and a (meth)acrylic monomer unit. The adhesive layer has a surface elastic modulus of 1-20 kPa at 23°C. The polymer (B) has a weight average molecular weight of 10,000-100,000.
