Patent ID: 7147905

Claim:
A laminate comprising at least a surface layer (I) and an adjacent layer (II) thereto, wherein the surface layer (I) comprises a cross-linked copolymer formed by cross-linking a copolymer prepared by using as monomers at least one vinyl aromatic compound and at least one conjugated diene compound, and the adjacent layer (II) comprises a hydrogenated copolymer formed by hydrogenating a copolymer prepared by using as monomers at least one vinyl aromatic compound and at least one conjugated diene compound, wherein the copolymer in the surface layer (I) and/or the adjacent layer (II) is a block copolymer; the conjugated diene compound used in the preparation of the copolymer in the surface layer (I) and/or the adjacent layer (II) includes isoprene and/or butadiene; the vinyl aromatic compound used in the preparation of the copolymer in the surface layer (I) and/or the adjacent layer (II) includes styrene; and the content of the vinyl aromatic compound in the copolymer in the surface layer (I) and/or the adjacent layer (II) is from 10 to 40% by weight.
