Abstract

A laminate which is obtained by providing a layer of an adhesive composition, wherein an epoxy-modified elastomer is blended, between a film of a thermoplastic resin or thermoplastic elastomer composition and a layer of a rubber composition, and in which the adhesion between the film and the layer of a rubber composition is further improved. This laminate is characterized in that: the adhesive composition contains a tackifying agent, a vulcanization accelerator, an elastomer and an unsubstituted or substituted aromatic carboxylic acid having a pKa of 1.5-4.0; 50-100% by mass of the elastomer is an epoxy-modified elastomer; and the amount of the aromatic carboxylic acid is 0.5-5 parts by mass per 100 parts by mass of the elastomer.
