[0131] There is no particular limitation on the preparation method of the PC resin composition of the present invention, and a previously known method can be used. Specifically, the above-mentioned (A) component aromatic polycarbonate resin (a-1) common PC resin and (a-2) PC-POS copolymer, (B) component glass filler, ( Component C) can be prepared by kneading a reactive functional group-containing polysiloxane compound, (D) glossy particles, a colorant preferably contained in component (E), and the above-mentioned various optional components used as necessary.
[0132] It can be pre-mixed with commonly used machines such as ribbon blenders, drums, etc., and then use Henschel mixers, Banbury mixers, single-screw extruders, and twin-screw extruders. , multi-shaft screw extruder and kneading extruder etc. for mixing and kneading. The heating temperature during kneading is normally selected appropriately within the range of 240 to 300°C.
[0133] In addition, components other th...

[0183] Each component was prepared by mixing the components in the mixing ratio shown in Table 1 and melt-kneading at 280°C using a twin-screw extruder [manufactured by Toshiba Machine Co., Ltd., model name "TEM-35B"]. PC resin composition particles.
[0184] Using each of the above pellets, test pieces were formed as described above, and the mechanical properties, flame retardancy, and optical properties were determined, and the results are shown in Table 1.

[0191] It can be seen from Table 1 that:
[0192] Examples 1 to 7 were added to a composition composed of a general PC resin and a PC-PDMS copolymer (hereinafter referred to as a specific PC resin) and a glass filler having a refractive index difference with the specific PC resin of 0.002 or less. The reactive functional group-containing polyorganosiloxane compound, glossy particles, and coloran...
