Title:
ADHESIVE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2015/080097
Kind Code:
A1
Abstract:
Provided is a new adhesive resin composition that can exhibit adhesiveness to an extent that allows separation in a room temperature state, and can exhibit fluidity through hot melting and ultimately cross-link so as to strongly adhere together two objects to be joined. Proposed is an adhesive resin composition containing 100 parts by mass of an acrylic copolymer (A), 0.5 to 20 parts by mass of a cross-linking agent (B), and 0.1 to 5 parts by mass of a photopolymerization initiator (C), said composition characterized in that the acrylic copolymer (A) is a graft copolymer having a weight-average molecular weight of 5.0×104 to 5.0×105, said graft copolymer contains repeating units derived from a (meth)acrylic acid ester as a stem component, said graft copolymer contains repeating units derived from a macromonomer having a number-average molecular weight of equal to or more than 5.0×102 and less than 6.0×103 as a branch component, and the macromonomer-derived repeating units are included at a proportion of 0.1 to 3 mol% in the acrylic copolymer (A).
