摘要：
A thermoplastic polycarbonate composition suitable for the preparation of optical storage devices, for instance optical discs, is disclosed. The composition, containing a stabilizing amount of partially fatty acid ester and as a stabilizer, a compound the structure of which contains at least one benzofuran-2-one group per molecule, features improved resistance to yellowing, reduced haze and high total light transmission values.
