Abstract
Disclosed herein is a polycarbonate resin composition. The polycarbonate resin composition includes: a polycarbonate resin; a polyalkylene glycol compound; and an anthraquinone colorant, wherein the polycarbonate resin composition has a yellow index (YI) of about −2 to about 2, as measured in accordance with ASTM D1925 after irradiating an about 3.2 mm thick specimen with γ-rays at about 25 kGy and leaving the specimen for 7 days and has an a* value of about −2 to about 2 and a b* value of −2 to about 2 as measured in accordance with ASTM D2244 after irradiating an about 3.2 mm thick specimen with γ-rays at about 25 kGy and leaving the specimen for 7 days. The polycarbonate resin composition can exhibit excellent properties in terms of color, transparency, and impact resistance after being irradiated with ionizing radiation.
