Abstract:
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.
