Abstract: A resin composition containing: a block copolymer (I) having a polymer block (a1) containing a structural unit derived from an aromatic vinyl compound and a polymer block (a2) containing a structural unit derived from a conjugated diene compound; a plasticizer (II); and a biomass-derived polyolefin-based resin (III); in which the plasticizer (II) contains a plasticizer (II-1) containing a biomass-derived raw material; and in which the resin composition has a biobased content of 45% by mass or more, and a molded body obtained by using the resin composition.

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.

Abstract: A 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).
