    摘要: This tire laminate comprises a film of a thermoplastic resin composition and a layer of a rubber composition laminated over said film, and is characterized in that the rubber composition contains at least one type of rubber component, a condensate of formaldehyde and the compound represented by formula (1) (R1 to R5 in the formula are defined in the specification), at least one type of methylene donor and a vulcanizing agent, and in that there are 0.5-20 parts by mass of the condensate per total 100 parts by mass of the at least one type of rubber component, there are 0.25-200 parts by mass of the at least one type of methylene donor per total 100 parts by mass of the at least one type of rubber component, the mass ratio of the at least one type of methylene donor and the condensate is 0.5:1-10:1, and, based on the total amount of the at least one type of rubber component, the at least one type of rubber component includes 4-40 parts by mass of a nitrile rubber that includes a carboxylic group in at least one side chain or terminal. This tire laminate exhibits improved adhesive strength between the film of the thermoplastic resin composition and the layer of the rubber composition.
