Reinforcing membrane, apparatus for attaching reinforcing membrane, and method for manufacturing thereof

Abstract

The reinforcing film (10) of the present invention comprises an adhesive layer (2) adhered to a main surface of a film substrate (1). The adhesive layer is formed of a photocurable composition comprising an acrylic-based polymer having a crosslinked structure, a photocuring agent, and a photopolymerization initiator. The photocuring agent comprises a polyfunctional (meth)acrylate containing an isocyanuric acid backbone. The reinforcing film of the present invention is easy to peel off immediately after being bonded to the substrate. After being bonded to the substrate, the adhesive can be photocured to firmly adhere to the substrate, and it is not easy to peel off from the substrate even when repeatedly bent and stretched.
