Disc substrate for optical use and molding material therefor |
| abstract |
A disc substrate for optical use which is formed from a polycarbonate resin which is obtained by the reaction of an aromatic dihydroxy compound and a carbonic diester and contains insoluble substances having a size greater than 30 νm and having a property of emitting a light when exposed to irradiation of a light having a wavelength of 380 nm in an amount of 100 pieces or less per 1 kg thereof; and a molding material therefor. The disc substrate for optical use is extremely reduced in the number of white spots being formed even after a long period of time and can be used for producing an optical disc which is highly stabilized in the reliability of writing into it and reading from it. |
