Abstract (en)
[origin: US2004063821A1] 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 R<1>, R<2>, R<3 >R<4>, R<5 >and R<6 >independently denote H, alkyl, aryl, heteroaryl or halogen, or where R<1>, R<2>, R<3>, R<4>, R<5>, R<6 >and R<7 >mutually independently stand for H, alkyl, aryl, heteroaryl, halogen or a cyano group.
