  • Patent number: 9802395
    Abstract: 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.
