<p>A transparent resin material consisting of a (co)polymer obtained by subjecting at least one compound represented by the general formula (I) or a combination of said compound and other copolymerizable monomer to metathesis polymerization, or a hydrogenation product of the (co)polymer: <CHEM> wherein A and B are independently hydrogen atoms or C1-10hydrocarbon groups; X and Y are independently hydrogen atoms, C1-10hydrocarbon groups, halogen atoms, halogen-substituted C1-10hydrocarbon groups, -(CH2)nCOOR<1>, -(CH2)nOCOR<1>, -(CH2)nOR<1>, -(CH2)nCN, -(CH2)nCONR<2>R<3>, -(CH2)nCOOZ, -(CH2)nOCOZ, -(CH2)nOZ or -(CH2)nW [R<1>, R<2>, R<3> and R<4> are independently C1-20hydrocarbon groups, Z is a halogen-substituted hydrocarbon group, W is SiR<5>pD3-p (R<5> is a C1-10hydrocarbon group, D is a halogen atom, -OCOR<5> or -OR<5>, p is 0 or an integer of 1-3), n is 0 or an integer of 1-10] with the proviso that at least one of X and Y is selected from the above groups other than the hydrogen atom and the hydrocarbon groups, or X and Y may form together <CHEM> and m is 0 or 1. Said transparent resin material is moldable and has sufficient optical properties, low hygroscopicity, good heat resistance and excellent adhesion to recording layer.</p> |
