Abstract
An adhesive tape has adhesive strength with high high-load holding power, temporal repeelability, and storage stability. The adhesive tape includes a substrate layer and an adhesive layer. The substrate layer has a breaking stress in a range of 1 to 100 MPa and an elongation at break in a range of 300% to 3000%. The adhesive layer contains a tackifier resin and a triblock copolymer with a repeating unit represented by the general formula (1): A, B, and C independently denote a repeating unit. A and C independently denote an alkyl methacrylate monomer unit and B denotes an alkyl acrylate monomer unit. p, q, and r independently denote the degree of polymerization of their respective monomer units. A and C may be the same or may denote an alkyl methacrylate monomer unit with a different chemical structure. * denotes a bonding arm to another atom.
