Abstract
An easily dismantlable adhesive composition is provided containing: an acrylic polymer; and either an acid catalyst or an acid generator, the acrylic polymer containing: as monomer components, a carboxyl-precursor-group-containing-(meth)acrylate monomer; an n-butyl acrylate; and a polar-group-containing monomer, the content of the polar-group-containing monomer being 5 to 30% by mass, relative to the total mass of the monomer components composing the acrylic polymer, makes it possible to realize favorable adhesion- and dismantling properties and favorable delamination at an interface between an adherend and a substrate or an interface between an adhesive agent layer and an adherend when dismantled.
