Polycarbonate resin composition for optical use.

摘要

This invention provides a polycarbonate resin composition for optical use and an optical disc substrate manufactured therefrom. Polycarbonate resin is mixed with at least one kind of carboxylic acid selected from aliphatic carboxylic acids having 1 to 10 carbon atoms in which hydrogen atoms of aliphatic group may be substituted by hydroxyl groups; or aromatic carboxylic acids in which hydrogen atoms of the aromatic ring may be substituted by low alkyl groups, hydroxyl groups, or halogen atoms. The amount of the carboxylic acids is 5 to 1000 ppm based on the polycarbonate resin.
