PROBLEM TO BE SOLVED: To provide a polycarbonate resin optical molding material having high definition transfer property which is suitable for definition transfer property and fast cycle molding property for the form of a stamper and which extremely suppresses deposition on the stamper as for the production of an optical recording medium by molding a polycarbonate resin, in particular, as for the production of a high-density recording medium. SOLUTION: The polycarbonate resin optical molding material having high definition transfer property has 24,000 to 40,000 weight average mol.wt. measured by a gel permeation chromatography(GPC), and contains 9 to 26 wt.% of the polycarbonate compound component having <=10,000 mol.wt. in the polycarbonate resin and <=12 wt.% of the polycarbonate compound component having >=60,000 mol.wt. |
