ABSTRACT:
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 towhere R1, R2, R3R4, R5and R6independently denote H, alkyl, aryl, heteroaryl or halogen, orwhereR1, R2, R3, R4, R5, R6and R7mutually independently stand for H, alkyl, aryl, heteroaryl, halogen or a cyano group.
