Abstract:
[Problem] To provide a composition for an adhesive agent, which can exhibit excellent adhesion properties even when exposed to heat-resistant conditions and enables the production of such an adhesive agent that the degree of staining of an adherend can be reduced upon the detachment of an adhesive sheet comprising the adhesive agent from the adherend.
[Solution] A composition for an adhesive agent, which comprises: (A) a (meth)acrylate ester polymer which is produced by RAFT polymerization, has a weight average molecular weight (Mw) of 60,000 to 200,000 as measured by a gel permeation chromatography method and a molecular weight distribution (Mw/Mn) of 3.0 or less, and has a constituent unit derived from a monomer containing a hydroxyl group; and (B) an isocyanate compound having three or more isocyanate groups per molecule.
