Abstract
A synthetic resin laminate is excellent in shape stability in high-temperature high-humidity environments and in surface hardness and usable for a transparent substrate material or protection material. A synthetic resin laminate includes a substrate layer containing a polycarbonate (B); and a resin layer laminated on one or both surfaces of the substrate layer, the resin layer containing a resin (A) that contains a (meth)acrylate copolymer (a1) and a polycarbonate (a2); wherein (a1) is a (meth)acrylate copolymer composed of 5 to 80% by mass of an aromatic (meth)acrylate unit (a11) and 20 to 95% by mass of a methyl methacrylate unit (a12); (a2) is a polycarbonate containing a constituent unit represented by formula [1]; and the ratio of (a1) with respect to the resin (A) is 5 to 55% by mass, and the ratio of (a2) with respect to the resin (A) is 95 to 45% by mass.
