Abstract

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.
