Abstract

An easily dismantlable adhesive composition containing: an acrylic block polymer having a poly(meth)acrylate chain (A) formed of a carboxyl precursor group-containing (meth)acrylate monomer (a) and a poly(meth)acrylate chain (B) that contains, as monomer components, a (meth)acrylate (b) having an alkyl group having 1 to 14 carbon atoms and a polar group-containing monomer (c); and either an acid catalyst or an acid generator, makes it possible to achieve favorable adhesiveness and dismantlability and suppress stick-slip at the time of dismantlement.
