Abstract:
1. A pressure-sensitive adhesive sheet for a tire comprising a substrate and an adhesive layer, wherein the adhesive layer includes a hot melt-type adhesive composition and satisfies the adhesive characteristics (A) and (B), where (A) loop tack adhesion at 5° C. is 14N/25 mm or more, and (B) loop tack adhesion at 40° C. is 5N/25 mm or more, and the hot melt-type adhesive composition comprises: (C) 15 to 40% by weight of an ABA-type block copolymer, (D) 30 to 70% by weight of two or more types of a tackifier having different softening points and (E) 10 to 40% by weight of plasticizer, as main components wherein, (C)′ the hot melt-type adhesive composition is a mixture of styrene-isoprene-styrene copolymer (SIS) as the ABA-type block copolymer and styrene-isoprene copolymer (S (D)′ with at least one out of the (D) two or more types of a tackifier having different softening points being a tackifier with a softening point of 60 to 100° C. as measured in accordance with JIS K 2207 standard.
