Abstract:
1. A re-peeling pressure-sensitive adhesive composition, which is used for a surface protecting material for an adherend having a photocatalytic layer, comprising: a (meth)acryl-based polymer; and a surfactant; wherein the surfactant has a molecular weight of 150 to 5000, in an amount from 0.01 to 30 parts by weight with respect to 100 parts by weight of the (meth)acryl-based polymer; and wherein the (meth)acryl-based polymer comprises, as monomer units: 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), wherein the surfactant is phosphoric ester surfactant.
