ABSTRACT:
A thermoplastic composition contains a polycarbonate resin, an aromatic vinyl copolymer, an impact modifier and a mineral filler, wherein the composition has a lightness L* of greater than or equal to about 70 under one or more of CIE D65, CWF-2 or C illumination using a 2° observer at 360 to 750 nanometers (nm), including specular components. Alternatively, a thermoplastic composition may contain a polycarbonate resin, a vinyl aromatic copolymer, an impact modifier and a mineral filler, and less than or equal to about 400 parts per million iron, by weight of the composition. An article may be formed by molding, extruding, shaping or forming such a composition to form the article.
