However, this resin composition is satisfactory in scratch resistance, chemical resistance and impact resistance, but has poor damage resistance, that is, poor light scratch resistance
Thus, the resin composition has limited application for frequently touched or easily contaminated components

[0123] The above components were mixed according to the composition listed in Table 1, and 0.2 parts by weight of carbon black was added thereto, followed by extruding with a 45Φ twin-screw extruder, and drying in a drier at 100° C. for 4 hours to obtain pellets. The pellets were dried at 80°C for 4 hours and injection molded to prepare ASTM dumbbell samples using a 6 oz injection molding machine with a barrel temperature of 210°C to 230°C, a mold temperature of 100°C, and a molding cycle of 30 seconds. The physical properties of these samples were measured as follows, and the results are shown in Tables 1 to 3.
[0124] (1) Blackness
[0125] The L value was determined by Konica Minolta CCM according to ASTM D1925 method.
[0126] (2) Notch-IZOD impact strength
[0127] Notch-IZOD (kgf·cm / cm) was measured on a sample having a thickness of 1 / 8" according to ASTM D256 method.
[0128] (3) Ball scratch profile (BSP) width

Abstract
The present invention relates to a polycarbonate resin composition and a molded article using the same. The polycarbonate resin composition having high gloss and impact resistance and good surface properties including 100 parts by weight of a base resinincluding a polycarbonate resin (A) and a polycarbonate-polysiloxane copolymer (B); and 0.1 to 10 parts by weight of polyalkylaryl siloxane (C) having a refractive index of 1.42 to 1.59. The composition exhibits high gloss and blackness and has excellent impact resistance, heat resistance and light resistance, and superior mar resistance, which is resistance to fine scratches, and thus it is properly used for non-coating products.
Description
technical field [0001] The present invention relates to polycarbonate resin compositions having high gloss and impact resistance and good surface properties, and molded articles using the same. More specifically, the present invention relates to a polycarbonate resin composition having high gloss and impact resistance, and a molded article using the composition, which maintains transparency while minimizing surface friction to have excellent damage resistance Sex, that is, light scratch resistance. Background technique [0002] Polycarbonate resins have excellent hardness, impact resistance, thermal stability, self-extinguishing properties, dimensional stability, and heat resistance, making them used in electrical and electronic components, automotive components, lenses, and as a glass substitute. However, when used in products that require transparency, polycarbonate resins are not as scratch-resistant as glass and turn yellow when exposed to sunlight for extended periods ...
