    摘要: The present invention has an object of providing a synthetic resin laminate that is excellent in shape stability against a high temperature and high humidity environment, surface hardness and the like. The above object is achieved by a synthetic resin laminate, comprising a substrate layer (B) containing polycarbonate; and a resin layer (A) laminated on one or both of two surfaces of the resin layer (B), the resin layer (A) containing 5 to 55% by mass of (meth)acrylate copolymer (C) and 95 to 45% by mass of polycarbonate (D), wherein the (meth)acrylate copolymer (C) contains an aromatic (meth)acrylate unit (c1) and a methyl methacrylate unit (c2) at a mass ratio (c1/c2) of 5-80/20-95, and the (meth)acrylate copolymer (C) has a mass-average molecular weight of 5,000 to 30,000; and the polycarbonate (D) has a mass-average molecular weight of 21,000 to 40,000.

    摘要: An optical sheet is formed by laminating, by co-extrusion molding, a first layer containing a polycarbonate resin, a second layer containing a polyamide resin, and a third layer, wherein the second layer is laminated between the first layer and the third layer, the first layer and second layer, and the second layer and third layer can each be peeled at the interface, and the outer surface of the first layer has a fine grooved structure. The optical sheet, which is provided with a plurality of layers in such a way, is capable of retaining, a sufficient amount of heat in a laminate in a mold since the entire sheet can be made thick during melt extrusion molding, and is able to improve the transferability of the fine grooved structure. In addition, the optical sheet can be made thinner by using only the peeled first layer as an optical sheet.
