Abstract
A composition for molding information carriers, such composition consisting of a uniformly kneaded mixture of (I) 100 parts by weight of a composite resin having a specific viscosity of 0.16 to 0.40 composed uniformly of (A) 90 to 40% by weight of a vinyl chloride resin portion having a specific viscosity of 0.16 to 0.28 and (B) 10 to 60% by weight of a methyl methacrylate portion having a specific viscosity of 0.10 tp 0.90, and (II) 1 to 10 parts by weight of molding additives, the specific viscosity being measured on a 100 ml. nitrobenzene solution containing 0.4g of the sample at 30.degree.C., the composition having a melt viscosity of 3 .times. 10.sup.3 to 3 .times. 10.sup.4 poises at 160.degree.C. at a shearing rate of 10.sup.3 sec.sup.-.sup.1 and a break elongation of at least 10% when stretched at 25.degree.C. at a tensile speed of 10mm/min.
