摘要：
A thermoplastic molding composition characterized by its optical brightness and good weathering resistance is disclosed. The composition contains a poly(ester) carbonate an optical brightener conforming to where R1, R2, R3 R4, R5 and R6 independently denote H, alkyl, aryl, heteroaryl or halogen, or where R1, R2, R3, R4, R5, R6 and R7 mutually independently stand for H, alkyl, aryl, heteroaryl, halogen or a cyano group.
