PROBLEM TO BE SOLVED: To provide an adhesive composition and an adhesive tape or sheet that is useful for outer use in medical, by oleic, sports, beauty, health and other fields as first-aid plasters and large plasters and dressing materials, especially has good low temperature and water-proof properties and is not sticky. SOLUTION: A liquid state rubber component of 30 to 170 parts by weight at a nomal temperature and 50 to 400 parts by weight of a takifier are added to of 100 parts by weight of solid rubber component at a nomal temperature. The takifier is set to become 25 to 80 parts by weight to 100 parts by weight of the total rubber component. It is preferably to use an A-B type block copolymer and an A-B-A type block copolymer as the solid rubber component at a nomal temperature. And it is preferable to use liquid polyisoprene, polybutadiene, polyisobutylene, polybutene, styrene/isoplene copolymer, isoplene/ butadiene copolymer and the like as the liquid rubber component at a nomal temperature. The adhesive composition is laied on one side of a backing film such as an olefinic film and others and the adhesive tape and sheet are consisted of them. |
