<p>PURPOSE: An adhesive composition is provided to form a balance of adhesion in a low-speed separation region and high-speed separation region, to prevent residue of adhesive on an object, and to have reworkability. CONSTITUTION: An adhesive composition consists of a copolymer comprising methacrylic acid ester monomer of which alkyl group carbon number is C4-10, an hydroxyl group-containing a copolymerizable monomer, a carboxy group-containing a copolymerizable monomer, a copolymerizable monomer, and carboxy group-containing a copolymerizable monomer, and further contains an isocyanate compound with three or greater functional groups, a crosslinking retarder, and a polyether-modified siloxane. In a surface protection film, an adhesive layer, which crosslinks the adhesive composition is formed on one side of the resin film.</p> |
