Abstract
PURPOSE:To provide a pressure-sensitive adhesive compsn. which is excellent in initial adhesion, adhesive strength and creeping properties and is improved in high-temp. heat treatment performance, and which comprises a block copolymer having a particular range of a vinyl bond content attributed to a conjugated diene compd. and a tackifier. CONSTITUTION:A pressure-sensitive adhesive compsn. comprises 100pts.wt. particular hydrogenated block copolymer (A) and 20-200pts.wt. tackifier (B). The block copolymer is prepd. by hydrogenating a block copolymer comprising at least one polymer block composed mainly of a vinyl arom. compd. and at least one polymer block composed mainly of a conjugated diene compd., said block copolymer having a vinyl bond content V attributed to the conjugated diene compd. of 10-80%. The hydrogenation rate A of the whole aliph. double bonds attributed to the conjugated diene compd. of the block copolymer is from 5% to less than 75%, and the hydrogenation rate B of the vinyl bonds attributed to the conjugated diene compd. of the copolymer satisfies B/V<1/2>=3-20. This compsn. is excellent in initial adhesion, adhesive strength and creeping properties and is improved in high-temp. heat treatment performance. This compsn. is suited for use in a pressure-sensitive adhesive tape, label etc.
