  • Patent number: 11951731
    Abstract: Provided are a multilayer body in which base materials composed of a metal, a resin or the like are firmly bonded to each other even when not subjected to primer treatment or the like, and a method for producing the multilayer body. The multilayer body has a base material (X), an adhesive layer (Y), and a base material (Z) in this order, wherein the adhesive layer (Y) contains a hydrogenated block copolymer (A) obtained by hydrogenating a block copolymer (P) containing a polymer block (a) composed of a structural unit derived from an aromatic vinyl compound and a polymer block (b) composed of a structural unit derived from a conjugated diene, the mass ratio [(a)/(b)] of the polymer block (a) to the polymer block (b) is 1/99 to 50/50, and the adhesive layer (Y) has a storage modulus G? at 100° C. of 1.2×105 to 4.0×105 Pa.
