Polycarbonate compositions
摘要:
A polycarbonate composition is disclosed comprising a polycarbonate resin, a 3-hydroxychromone dye, and an ultraviolet absorber selected from the group consisting of cyanoacrylates, malonates, and oxanilides. The combination of the 3-hydroxychromone dye and ultraviolet absorber results in a composition with good color retention and strong initial fluorescent emission intensity.
