Abstract
There is provided a new pressure-sensitive adhesive resin composition that can have adhesiveness to the extent of being peelable in a room temperature condition, has fluidity by hot-melting, and can finally be crosslinked to firmly bond adherends to each other. There is proposed a pressure-sensitive adhesive resin composition comprising 100 parts by mass of an acrylic copolymer (A), 0.5 to 20 parts by mass of a crosslinking agent (B), and 0.1 to 5 parts by mass of a photopolymerization initiator (C), wherein the acrylic copolymer (A) is a graft copolymer having a weight average molecular weight of 5.0×10to 5.0×10, contains as a trunk component of the graft copolymer a repeating unit derived from a (meth)acrylate, contains as a branch component of the graft copolymer a repeating unit derived from a macromonomer having a number average molecular weight of 5.0×10or more and less than 6.0×10, and contains the repeating unit derived from the macromonomer in the acrylic copolymer (A) in a proportion in a range of 0.1 to 3 mol %.
