CORRUGATED MOLDING PLATE

PROBLEM TO BE SOLVED: To provide a corrugated molding plate extremely excellent in solar reflectance and weather resistance without impairing heat resistance, mechanical characteristics or the like which a polycarbonate resin originally has.SOLUTION: There is provided a corrugated molding plate which comprises: a core layer containing a polycarbonate resin (A), a near infrared ray-reflective pigment (B) and a cyclic phosphorous acid ester-based antioxidant (C) in which the infrared ray-reflective pigment (B) is a specific composite oxide pigment having an average particle diameter of 2 μm or less and the amount of the near infrared ray-reflective pigment (B) is 0.01 to 20 pts.wt. based on 100 pts.wt. of the polycarbonate resin (A); and a cap layer which contains an ultraviolet absorber (D) composed of the polycarbonate resin (A) and a combination comprising benzotriazole, triazine, cyanoacrylate or one or more thereof and in which one surface is arranged to adhere to the core layer.SELECTED DRAWING: None 【課題】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、日射反射性及び耐候性に極めて優れる波型成形板の提供。【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）と環状亜燐酸エステル系酸化防止剤（Ｃ）とを含むコア層であって、該近赤外線反射顔料（Ｂ）が平均粒径が２μｍ以下の特定の複合酸化物顔料であり、該近赤外線反射顔料（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重量部であるコア層と、ポリカーボネート樹脂（Ａ）とベンゾトリアゾール、トリアジン、シアノアクリレート又は一種以上を含む組み合わせからなる紫外線吸収剤（Ｄ）とを含み、その一方の表面が該コア層に密着配置されたキャップ層を備える波型成形板。【選択図】なし
