1. A cyclic carbodiimide compound which is represented by the following Formula (O-1) or (O-2): wherein each of R1 and R5 independently represents an alkyl group, an aryl group, or an alkoxy group; each of R2 to R4 and R6 to R8 independently represents a hydrogen atom, an alkyl group, an aryl group, or an alkoxy group; R1 to R8 may be bonded to each other to form a ring; each of X1 and X2 independently represents a single bond, —O—, —CO—, —S—, —SO2—, —NH—, or —CH2—; and L1 represents a divalent linking group; wherein each of R11, R15, R21 and R25 independently represents an alkyl group, an aryl group, or an alkoxy group; each of R12 to R14, R16 to R18, R22 to R24, and R26 to R28 independently represents a hydrogen atom, an alkyl group, an aryl group, or an alkoxy group; R11 to R28 may be bonded to each other to form a ring; each of X11, X12, X21, and X22 independently represents a single bond, —O—, —CO—, —S—, —SO2—, —NH—, or —CH2—; and L2 represents a tetravalent linking group. |
