Abstract:
Provided is an adhesive agent composition that firmly adheres to an adherend having a relatively high polarity, an adherend having a relatively low polarity, an adherend to which adhesion is difficult such as ethylenepropylene diene rubber (EPDM), and a rough surface, that has high holding power, that has excellent adhesiveness in high temperatures and in high humidity environments, and that has a slower reduction in adhesiveness over time. The adhesive agent composition contains an acrylic resin (A) obtained by copolymerization of copolymer components (a) including specific amounts of: (a1) at least one selected from the group consisting of (meth)acrylates having an alkyl group having 1-3 carbon atoms, t-butyl(meth)acrylate, cyclic structure-containing monomers, and vinyl ester monomers having 3-10 carbon atoms; (a2) a (meth)acrylate having an alkyl group having 4-24 carbon atoms (excluding t-butyl(meth)acrylate); (a3) a terminal carboxyl group-containing monomer having a specific structure; and (a4) a (meth)acrylic acid.
