Pressure-sensitive adhesive material |
摘要 |
A pressure-sensitive adhesive material comprises a pressure-sensitive adhesive layer comprising 100 parts by weight of natural rubber and 10 to 120 parts by weight of styrene-isoprene-styrene block copolymer (SIS) having a radiate configuration with a styrene content of 10 to 45% by weight. Preferably, the pressure-sensitive adhesive layer is free of metals or metal compounds. The pressure-sensitive adhesive layer may contain 5 to 150 parts by weight of a tackifier having an acid value of 1.5 or more. The pressure-sensitive adhesive material includes (A) a backing-less tape having a release liner having on one surface thereof the pressure-sensitive adhesive layer and (B) a double-coated tape having a backing having respective pressure-sensitive adhesive layers on surfaces thereof, at least one of which is constituted by the pressure-sensitive adhesive layer of the above-described type.
