| description | A polycarbonate resin molding material for optical use which is pellets formed from a polycarbonate resin and having a bulk density of 0.72 kg/l or more and an optical disk substrate formed therefrom.
According to the present invention, use of the above pellets makes it possible to obtain an optical disk substrate which rarely experiences the production of a silver streak, reduce the molding cycle and smoothen the molding operation. |
