Title:
LAMINATE CONTAINING HYDROGENATED COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2004/101269
Kind Code:
A1
Abstract:
A laminate comprising a base layer, an adhesive layer, and a hydrogenated copolymer composition layer which is bonded to the base layer via the adhesive layer is characterized in that the hydrogenated copolymer composition layer is composed of a hydrogenated copolymer (I) and a rubbery polymer (II) and the hydrogenated copolymer (I) is obtained by hydrogenating a conjugated diene-vinyl aromatic copolymer and has the following features (1)-(4): (1) the content of the vinyl aromatic monomer unit is more than 50 weight% but not more than 90 weight%; (2) the content of the vinyl aromatic block is not more than 40 weight%; (3) the weight-average molecular weight of the copolymer (I) is from 50,000 to 1,000,000; and (4) the hydrogenation ratio of the double bond of the conjugated diene monomer unit is not less than 70%.
