Patent ID: 8524729

Claim:
A composition comprising a 2(1H)-pyridinone compound represented by the formula (XVIII): wherein X III ′ represents a C2-C4 alkyl group, or a C1-C4 alkyl group substituted with a halogen atom or a C1-C4 alkoxy group, or a C2-C4 alkenyl group, or a C2-C4 alkenyl group, or a C2-C4 alkoxy group, or a R I —S(O) I -group (wherein R I represents a C1-C4 alkyl group, and l represents an integer of 0 to 2), or a cyano group, or a carboxy group, or a C1-C4 alkoxycarbonyl group, a (R II ) 2 N-group (wherein R II represents a C2-C4 alkyl group), or a R I —CO—NH-group (wherein R I is as defined above), or a R I O—CO—NH-group (wherein R I is as defined above), or a R I NH—CO—NH-group (wherein R I is as defined above), or a (R I ′) 2 N—CO-group (wherein R I ′ represents a hydrogen atom or a C1-C4 alkyl group), or a RB-group (wherein B represents an oxygen atom or a sulfur atom, and R represents a C1-C4 alkyl group substituted with a halogen atom), X III ″represents a hydrogen atom, a halogen atom, a C1-C4 alkyl group, or a C1-C4 alkoxy group, m represents 1 or 2, when m is 2, X III ″'s may be different, and r II and r II ′ are the same or different, and represent a hydrogen atom or a C1-C4 alkyl group; and an inert carrier.
