Provided is a re-peeling pressure-sensitive adhesive composition for a surface protecting material for an adherend having a photocatalytic layer, comprising: a (meth)acryl-based polymer including, as monomer units, 50 to 99.9% by weight of (A) at least one acrylate-based monomer represented by the general formula (1): CH2═CR1COOR2 wherein R1 represents a hydrogen atom or a methyl group, and R2 represents an alkyl group having 2 to 14 carbon atoms, 0.1 to 10% by weight of (B) a functional-group-containing vinyl-based monomer, and 0 to 49.9% by weight of (C) a vinyl-based monomer copolymerizable with the component (A) and/or the component (B); and (D) a surfactant having a molecular weight of 150 to 5000, the amount of the component (D) being from 0.01 to 30 parts by weight with respect to 100 parts by weight of the (meth)acryl-based polymer. The re-peeling pressure-sensitive adhesive composition is excellent in re-peeling property, contact-angle-recoverability, and weather resistance.
