PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive sheet for removal of a solvent-containing substance which demonstrates sufficient cohesive force even in the case of short-time aging, and which demonstrates excellent cleaning performance and solvent absorption capability. SOLUTION: The pressure-sensitive adhesive sheet for removal of the solvent-containing substance contains a substrate and a pressure-sensitive adhesive layer which is formed on at least one side of the substrate, wherein the pressure-sensitive adhesive layer is characteristically formed by a pressure-sensitive adhesive composition containing (A) an acrylic polymer containing carboxyl group, (B) an amine based compound containing plural hydroxyl groups, and (C) a polyisocyanate based compound. In the pressure-sensitive adhesive composition forming the pressure-sensitive adhesive layer, it is preferred that the ratio of the amine based compound (B) containing plural hydroxyl groups and that of the polyisocyanate based compound (C) to 100 parts by weight of the acrylic polymer containing carboxyl group (A) are 0.1 to 50 parts by weight and 5 to 50 parts by weight, respectively.
