Adhesive compositions and pneumatic tire

An adhesive composition characterized in that 14-205 parts by weight as a solid content of a thermosetting resin including a resol condensate obtained by a resol-forming reaction between resorcin and formaldehyde and a novolak condensate obtained by a novolak-forming reaction between resorcin and formaldehyde is included based on 100 parts by weight as a solid content of vinylpyridine-styrene-butadiene sequential copolymer rubber latex containing 20-100% by weight of vinylpyridine-styrene-butadiene sequential copolymer obtained by sequential-polymerization of (a) a monomer mixture of 3-25% by weight of a pyridine ring containing compound, 25-80% by weight of an unsubstituted or substituted styrene, or of an unsubstituted or substituted styrene and an aliphatic vinyl compound, and 5-60% by weight of a conjugated diene compound, and (b) a monomer mixture of 5-25% by weight of a pyridine ring containing vinyl compound, 5-45% by weight of an unsubstituted or substituted styrene, or of an unsubstituted or substituted styrene and an aliphatic vinyl compound, and 40-83% by weight of a conjugated diene compound, in which a weight ratio of a copolymer component (a') obtained by the polymerization of the monomer mixture (a) to a copolymer component (b') obtained by the polymerization of the monomer mixture (b) in the resulting vinylpyridine-styrene-butadiene type sequential copolymer is 10/90-80/20, and the content of the conjugated vinyl compound in the monomer mixture (b) is higher than that in the monomer mixture (a).
