Abstract

The object of the present invention is to provide an alkali-dispersible hot melt pressure-sensitive adhesive which (i) has a high alkali-dispersibility, (ii) is excellent in strength to retain the label, (iii) hardly causes an adhesive residue problem and (iv) is capable of reducing stringing. The present invention relates to an alkali-dispersible hot melt pressure-sensitive adhesive comprising: (A) a thermoplastic block copolymer which is a copolymer of a vinyl-based aromatic hydrocarbon and a conjugated diene compound, (B) a tackifier resin and (C) at least one selected from the group consisting of a fatty acid and a derivative thereof, wherein the thermoplastic block copolymer (A) comprises (A1) a styrene-based block copolymer having a styrene content of less than 40 mass % and the tackifier resin (B) comprises an α-methylstyrene-based resin.
