摘要

An imidazolidine compound represented by formula (1). (In the formula, each of R1 and R2 independently represents a hydrogen atom, an optionally substituted alkyl group or an optionally substituted aryl group, or alternatively R1 and R2 combine with each other and form a ring together with a carbon atom to which R1 and R2 are bonded; each of R3 and R4 independently represents a phenyl group having at least three substituents among which at least one substituent is a halogen atom; and R5 represents an alkyl group.)
