A laminate of an air permeation preventive layer an adhesive layer provided with an air permeation preventive layer comprising a thermoplastic elastomer composition containing a thermoplastic resin as a continuous phase and a rubber composition dispersed therein as a dispersed phase and arranged on one surface of the air permeation preventive layer, an adhesive composition layer having a thickness of 100 μm or less, a self tack of less than 5N and a tack to an unvulcanized diene-based rubber or 5N or more, containing 100 parts by weight of a thermoplastic elastomer containing 50 parts by weight or more of an epoxy-modified styrene-butadiene-based block copolymer so that a total of 30 to 200 parts by weight of a terpene resin and an aromatically modified terpene resin having a weight average molecular weight Mw of 1000 or less and a softening point of 60 to 120° C., 0.1 to 3 parts by weight of an internal mold release agent and 0.1 to 2 parts by weight of an organic peroxide.
A laminate of an air permeation preventive layer/an adhesive layer provided with (I) an air permeation preventive layer comprising a thermoplastic elastomer composition containing a thermoplastic resin, as a continuous phase, and a rubber composition dispersed therein, as a dispersed phase, and (II) arranged on one surface of the air permeation preventive layer, an adhesive composition layer having a thickness of 100 μm or less formed from an adhesive composition having a self-tack of less than 5N and a tack to an unvulcanized diene-based rubber of 10.1-20N containing (i) a total of 100 parts by weight of a thermoplastic elastomer containing 50 parts by weight or more of an epoxy-modified styrene-butadiene-based block copolymer so that an oxirane oxygen content becomes 1 to 3% by weight, (ii) a total of 30 to 200 parts by weight of a terpene resin (A) having a weight average molecular weight Mw of 1000 or less and a softening point of 60 to 120° C. and an aromatically modified terpene resin (B) having a weight average molecular weight Mw of 1000 or less and a softening point of 60 to 120° C., in a ratio by weight of (A):(B)=70:30 to 50:50, (iii) 0.1 to 3 parts by weight of an internal mold release agent and (iv) 0.1 to 2 parts by weight of an organic peroxide having a one-minute half-life temperature of 160° C. or more.
