ABSTRACT:
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: ##STR1## wherein A and B are independently hydrogen atoms or C.sub.1-10 hydrocarbon groups; X and Y are independently hydrogen atoms, C.sub.1-10 hydrocarbon groups, halogen atoms, halogen-substituted C.sub.1-10 hydrocarbon groups, --(CH.sub.2).sub.n COOR.sup.1, --(CH.sub.2).sub.n OCOR.sup.1, --(CH.sub.2).sub.n OR.sup.1, --(CH.sub.2).sub.n CN, --(CH.sub.2).sub.n CONR.sup.2 R.sup.3, --(CH.sub.2).sub.n COOZ, --(CH.sub.2).sub.n OCOZ, --(CH.sub.2).sub.n OZ or --(CH.sub.2).sub.n W [R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are independently C.sub.1-20 hydrocarbon groups, Z is a halogen-substituted hydrocarbon group, W is SiR.sub.p.sup.5 D.sub.3-p (R.sup.5 is a C.sub.1-10 hydrocarbon group, D is a halogen atom, --OCOR.sup.5 or --OR.sup.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 ##STR2## 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.
