摘要： 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 × 10 5 to 4.0 × 10 5 Pa.

摘要： The present invention provides a gel composition which is able to be easily filled in the protective tube or cable during manufacturing a cable, is high in a dropping point (temperature of change from a semisolid to a liquid), and has such a characteristic that even in the case where the protective tube or cable is broken, the filling material does not flow out from the interior under a wide-range temperature and is also able to prevent water from penetration into the interior. The gel composition is a gel composition containing a base oil (a) and a hydrogenated block copolymer (b), wherein the hydrogenated block copolymer (b) is a hydrogenated product of a diblock copolymer composed of a polymer block (A) consisting mainly of a structural unit derived from an aromatic vinyl compound and a polymer block (B) consisting mainly of a structural unit derived from a conjugated diene compound, the content of the polymer block (A) in the hydrogenated block copolymer (b) being 38.0 to 45.0% by mass; and the content of the hydrogenated block copolymer (b) in the gel composition is 1 to 20 parts by mass based on 100 parts by mass of the total amount of the base oil (a) and the hydrogenated block copolymer (b).
