摘要： The present invention has an object of providing a synthetic resin laminate that is usable for a transparent substrate material or protective material, has high thermoformability (pressure formability, thermal-bending formability), high insert moldability, and high surface hardness and/or impact resistance, and also providing a molded body formed by molding such a synthetic resin laminate. The synthetic resin laminate includes a polycarbonate-based substrate layer; and a resin laminated on one of, or both of, two surfaces of the polycarbonate-based substrate layer, the resin containing a specific (meth)acrylate copolymer resin and a specific polycarbonate resin. The polycarbonate-based substrate layer includes a polymer alloy and thus has a glass transition temperature (Tg) of 110 to 130° C. Thus, the resultant synthetic resin laminate has high thermoformability and high surface hardness.

摘要： A synthetic resin laminated sheet, in which whitening, cracking, and foaming do not occur when thermoforming is carried out, in particular when deep-draw molding is carried out, and defects do not occur during lamination of a hard coating layer; and a molded article obtained by molding the laminated sheet. A synthetic resin laminated sheet has a coating layer, which includes an acrylic resin, laminated on one surface of a substrate layer including a polycarbonate resin in which a monohydric phenol represented by general formula (1) is used as a chain terminator and is obtained by reacting the monohydric phenol with a dihydric phenol and a carbonate binding agent and has a viscosity average molecular weight of 18000-35000. (In the formula, R1 represents a C8-36 alkyl group or a C8-36 alkenyl group. R2-R5 each represent hydrogen, halogen, or an optionally substituted C1-20 alkyl group or C6-12 aryl group).

摘要： The present invention provides a synthetic resin laminate, which is excellent in terms of shape stability in a high-temperature or high-humidity environment, surface hardness, heat resistance, coating adhesion and the like. The synthetic resin laminate is formed by laminating a resin layer (A) including 5% to 55% by mass of a (meth)acrylate copolymer (C) and 95% to 45% by mass of a polycarbonate (D) on one surface or both surfaces of a base material layer (B) comprising polycarbonate, wherein the synthetic resin laminate is characterized: in that the (meth)acrylate copolymer (C) includes an aromatic (meth)acrylate unit (c1) and a methyl methacrylate unit (c2) at a mass ratio (c1/c2) of 5 to 80/20 to 95; in that the mass average molecular weight of the (meth)acrylate copolymer (C) is 5,000 to 30,000; and in that the viscosity average molecular weight of the polycarbonate (D) is 21,000 to 40,000.
