Abstract:
A metal/synthetic resin laminate comprising a metal substrate layer; an epoxy resin-based adhesive layer (a ""1st adhesive layer""); an adhesive layer (a ""2nd adhesive layer"") comprising an epoxidized styrenic thermoplastic elastomer D prepared by epoxidation of a double bond derived from a conjugated diene compound of a block copolymer C comprising a polymer block A composed mainly of a styrenic compound and a polymer block B composed mainly of a conjugated diene compound or a partial hydrogenation product thereof; and a synthetic resin layer;wherein said 1st adhesive layer is adherent to the metal substrate layer and has affinity with the thermoplastic elastomer D of the 2nd adhesive layer and said second adhesive layer, which is different than the 1st adhesive layer, is adherent to the synthetic resin layer and provides elasticity to absorb contraction stress resulting from differences in linear expansion coefficients of the synthetic resin and the metal substrate.
