Adhesive sheet and polishing pad with adhesive sheet

Abstract

The present invention aims to provide an adhesive sheet excellent in both shear strength and slurry resistance at high temperature and excellent in removability that enables removal without adhesive residue. The present invention also aims to provide a polishing pad with an adhesive sheet including the adhesive sheet. Provided is an adhesive sheet including at least one adhesive layer, the adhesive layer containing a base polymer, a tackifier resin (T1) having a hydroxy value of less than 20 mgKOH/g, and a tackifier resin (T2) having a hydroxy value of 20 mgKOH/g or more and 120 mgKOH/g or less, the base polymer being a block copolymer of a monovinyl-substituted aromatic compound and a conjugated diene compound, and the adhesive layer containing the tackifier resin (T1) in an amount of 10 parts by weight or more and 60 parts by weight or less relative to 100 parts by weight of the base polymer, and the tackifier resin (T2) in an amount of 1 part by weight or more and 40 parts by weight or less relative to 100 parts by weight of the base polymer.
