Abstract

PURPOSE:To provide the title composition having specific breaking strength and room temperature hardness, and excellent tackiness, by compounding a rubber containing a specific block copolymer elastomer, with a tackifier and a sofetening agent. CONSTITUTION:A pressure sensitive adhesive composition having a breaking strength of 7-50kg/cm<2> at room temperature, a room temperature hardness of <=10 measured by a spring hardness tester, and <=3 after 30 seconds, a hardness of <=35 at -10 deg.C, and <=10 after 30 seconds, and composed of (a) 100 parts by weight of a rubber containing a vinyl aromatic compound/conjugated diene compound block copolymer elastomer of formulas I-IV [A is a block composed mainly of a vinyl aromatic compound; B is a block composed mainly of a conjugated diene compound; C is a random or tapered copolymer segment inserted between (A) and (B); X is a coupling agent which couples the blocks A-C-B; n is 3-20], (b) 20- 200 parts by weight of a tackifier such as rosin, 5C petroleum resin, etc., and (c) 10-150 parts by weight of a softening agent such as process oil, liquid oligomer resin, etc.
