Abstract

The present invention was made in view of the foregoing problem and has an object to provide a photocurable resin composition which can be quickly cured by irradiation with active energy rays such as ultraviolet rays and achieves excellent adhesion to polyolefin such as PP having properties difficult to bond. Specifically, provided is a photocurable resin composition containing the following (A) and (B) ingredients: (A) ingredient: a polymer having a polyisobutylene backbone mainly containing a —[CHC(CH)]— unit, the polymer having one or more (meth)acryloyl groups per molecule; and (B) ingredient: a photo-radical initiator of hydrogen abstraction type.
