1. A strippable adhesive composition comprising:
at least one block copolymer (A); and a solvent (B); wherein said at least one block copolymer (A) comprises a frame, and the frame comprises at least two vinyl aromatic polymer blocks and at least one hydrogenated and conjugated diene polymer block, and a hydrogenation ratio of the hydrogenated and conjugated diene polymer block is from 50 mol % to 100 mol %; and the solvent (B) comprises a cycloalkane organic solvent having 6 to 23 carbon atoms (B-1) and a naphthalene organic solvent (B-2); wherein the cycloalkane organic solvent having 6 to 23 carbon atoms (B-1) is methyl cyclohexane, ethyl cyclohexane, propyl cyclohexane, n-butyl cyclohexane, 2-methylpropyl cyclohexane, 2-cyclohexyloctane, 9-cyclohexylheptadecane, 1,2-dicyclohexylethane, or 1,1-dicyclohexyltetradecane; and the naphthalene organic solvent (B-2) is 1-methylnaphthalene, dimethylnaphtalene, 1-phenylnaphthalene, 1-chloronaphthalene, or 1-bromo-2-methylnaphthalene; wherein a ratio of the cycloalkane organic solvent having 6 to 23 carbon atoms (B-1) to the naphthalene organic solvent (B-2) in the solvent (B) is from 1 to 6. |
