<p><P>PROBLEM TO BE SOLVED: To provide: a tackifier composition that can make a film adhere firmly to unvulcanized rubber, wherein a laminate thus obtained is prevented from causing cracks at low temperature; a method of bonding the film and the unvulcanized rubber by using the tackifier composition; and a pneumatic tire. <P>SOLUTION: The tackifier composition contains an elastomer component comprising: 20 to 100 mass% of at least two epoxy-modified styrene-butadiene-styrene block copolymers having different oxirane oxygen densities; and 80 mass% or lower of other elastomers. The method of bonding the film and the unvulcanized rubber includes: arranging the tackifier composition in a space between the film and the unvulcanized rubber; and bonding the film and the unvulcanized rubber through vulcanization. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
