Abstract
A hydrogenated copolymer-containing laminate comprising a substrate layer, an adhesive layer, and a hydrogenated copolymer composition layer which is laminated on and bonded to the substrate layer through the adhesive layer, the hydrogenated copolymer composition layer comprising a hydrogenated copolymer (I), and a rubbery polymer (II), wherein the hydrogenated copolymer (I) is obtained by hydrogenating a conjugated diene/vinyl aromatic compound copolymer, the hydrogenated copolymer (I) having the following characteristics (1) to (4): (1) a vinyl aromatic monomer unit content of from more than 50% by weight to 90% by weight, (2) a content of a vinyl aromatic polymer block of not more than 40% by weight, (3) a weight average molecular weight of from 50,000 to 1,000,000, and (4) a hydrogenation ratio of 70% or more, as measured with respect to the double bonds in conjugated diene monomer units.
