Abstract:
A multilayer body includes at least one layer (C) including a resin composition; and at least one layer (D) including a thermoplastic resin, in which the resin composition includes a polycarbonate resin (A) and an acrylic resin (B) in a weight ratio of 40:60 to 99:1, the polycarbonate resin (A) includes, as main repeating units, a unit (a-1) represented by the following formula (a-1): and a unit (a-2) represented by the following formula (a-2): wherein W represents an alkylene group having 1 to 20 carbon atoms or a cycloalkylene group having 6 to 20 carbon atoms, R represents a branched or linear alkyl group having 1 to 20 carbon atoms, or a cycloalkyl group having 6 to 20 carbon atoms and optionally having a substituent, and m represents an integer of 0 to 10, and the molar ratio of the unit (a-1) and the unit (a-2) (a-1/a-2) is 40/60 to 95/5. The multilayer body has excellent transparency, chemical resistance, surface hardness, and adhesion.
