Zusammenfassung:SOLUTION: There is provided a polycarbonate resin composition which is a resin composition containing a polycarbonate resin (A), a near-infrared reflective pigment (B), an inorganic near-infrared absorber (C) and an antioxidant (D), as essential components, where an amount of the near-infrared reflective pigment (B) is 0.01-20 pts.wt. of 100 pts.wt. of the polycarbonate resin (A), and an amount of the inorganic near-infrared absorber (C) is 0.001-2 pts.wt. of 100 pts.wt. of the polycarbonate resin (A).EFFECT: A polycarbonate resin composition does not impair heat resistance and mechanical physical properties inherent to a polycarbonate resin, is inexpensive because of dispensing with a special step, and is excellent in solar reflectance, visible light transmittance and solar transmittance. For this reason, the polycarbonate resin composition can be suitably used as a resin sheet of various applications such as interior, exterior, a building material, an industrial material, an agricultural material, a member for vehicle, a member for ship and a member for aircraft.SELECTED DRAWING: None 【解決手段】ポリカーボネート樹脂(A)と近赤外線反射顔料(B)と無機系近赤外線吸収剤(C)と酸化防止剤(D)とを必須成分として含有してなる樹脂組成物であって、近赤外線反射顔料(B)の量が、該ポリカーボネート樹脂(A)100重量部に対して0.01〜20重量部、無機系近赤外線吸収剤(C)の量が、該ポリカーボネート樹脂(A)100重量部に対して0.001〜2重量部であることを特徴とする、ポリカーボネート樹脂組成物。【効果】本発明のポリカーボネート樹脂組成物は、ポリカーボネート樹脂が本来有する耐熱性、機械物性等を損なうことなく、特別な工程が不要なため安価で、日射反射性、可視光透過性及び日射透過性に優れる。このため、インテリア、エクステリア、建装材、産業資材、農業資材、車両用部材、船舶用部材、航空機用部材等の様々な用途の樹脂シートとして好適に用いることができる。【選択図】なし
