摘要： An optical disk substrate made from a polycarbonate resin prepared from at least one dihydric phenol selected from the group consisting of 2,2-bis(4-hydroxyphenyl)butane, 2,2-bis(4-hydroxyphenyl)-3-methylbutane, 2,2-bis(4-hydroxyphenyl)-4-methylpentane, and 2,2-bis(4-hydroxyphenyl)-3,3-dimethylbutane, the dihydric phenol amounting to 30 to 100 % by mole of the whole dihydric phenol component. The number of unacceptable surface irregularities of the substrate is 0 to 1, and the polycarbonate resin satisfies the requirements that (A) the specific viscosity measured as a solution of 0.7 g of the resin in 100 ml of methylene chloride at 20 DEG C is 0.2 to 0.4; (B) the number of insoluble particles measured as a solution of the polycarbonate resin in methylene chloride is not more than 25,000 per g of the polycarbonate resin in terms of the number of particles having an equivalent diameter of not less than 0.5 mu m and not more than 500 per g of the polycarbonate resin in terms of the number of particules having an equivalent diameter of not less than 1 mu m; and (C) the water absorption is not more than 0.2 % by weight. This substrate enables pits or grooves to be accurately transferred, is less likely to cause warpage derived from absorption of moisture, and has a high-density recording capacity. It has high functions suitable particularly for use as an optical disk substrate for video disks or the like.
