(57) 【Abstract】 PROBLEM TO BE SOLVED: An acrylic adhesive that not only has excellent foaming resistance and peeling resistance under high temperature and high humidity, but also can be easily peeled off again without adhesive residue after being once bonded. An agent composition is provided. SOLUTION: An acrylic resin containing an alkyl (meth) acrylate having an alkyl group having 2 to 12 carbon atoms as a main component and having a weight average molecular weight Mw of 700,000 to 2,000,000 and Mw / Mn of 1.5 to 4. 100 parts by weight of the polymer and 0.001 to 5 parts by weight of a cross-linking agent, which is at least one kind of an organic compound, an organometallic compound and a metal salt, each having a plurality of functional groups capable of forming a crosslink with a carboxyl group, An acrylic pressure-sensitive adhesive composition containing 0.01 to 5 parts by weight of the polyether-modified silicone oil of 0.1 to 0.1 to 10 parts by weight of a polyether having at least an alkoxysilyl group in the molecule. |
