    Abstract: A plastic article is described having a thickness of 0.5 mm to 5 mm, comprising a polycarbonate thermoplastic composition including polycarbonates containing phthalimidine carbonate units, said composition providing a heat deflection temperature of at least 145° C., a light transmittance of at least 85%, and CIE 1976 L*, a*, b* values of L* greater than 92, a* between −1.5 and 1.5, and b* between −2.0 and 3.0, when tested in the form of a 3.2 mm thick test sample molded at 580° F. (304° C.) with a 1.7 minute residence time, using CIE illuminant C and 2 degree observer.
