Abstract:
A plastic lens formed of a copolycarbonate resin comprising a structural unit (I) of the following general formula (I), and a structural unit (II) of the following formula (II), the structural unit (I) having a molar amount percentage of 15 to 85% on the basis of the total amount of the structural units (I) and (II),wherein, in said structural unit (II), each of R1 and R2 is independently a halogen atom, an alkyl group having 1 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, a cycloalkyl group having 6 to 20 carbon atoms, a cycloalkoxy group having 6 to 20 carbon atoms, an aryl group having 6 to 10 carbon atoms, an aralkyl group having 7 to 20 carbon atoms, an aryloxy group having 6 to 10 carbon atoms or an aralkyloxy group having 7 to 20 carbon atoms, each of q and r is independently an integer of 0 to 4, W is a group represented by wherein R3 and R4 are the same as, or different from, each other and each is a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms, each of R5 and R6 is independently a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, p is an integer of 4 to 7, and each of R7 and R8 is independently a hydrogen atom, a halogen atom or an alkyl group having 1 to 3 carbon atoms.
