PRESSURE-SENSITIVE ADHESIVE COMPOSITION, PROCESS FOR PRODUCING SAME, AND PRESSURE-SENSITIVE ADHESIVE LAYER AND PROCESS FOR PRODUCING SAME

摘要

A pressure-sensitive adhesive composition which comprises 100 parts by mass of (A) a hydrogenated block copolymer composition, 0.01-5 parts by mass of (B) a compound having a molecular weight of 2,000 or lower, and (C) a solvent which is an aliphatic hydrocarbon and/or aromatic hydrocarbon that is a liquid at 23°C, wherein the hydrogenated block copolymer composition (A) comprises (1) a product of hydrogenation of a block copolymer (a1) represented by the general formula (A-B)n and (2) a product of hydrogenation of a block copolymer (a2) represented by the general formula A-B-A or (A-B)m-X, and both the hydrogenated block copolymer composition (A) and the compound (B) have dissolved in the solvent (C).
