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. |
