Patent ID: 7193080

Claim:
An azomethine dye compound represented by formula (II): wherein Q represents a residue that forms, together with the —N—C═N— moiety, a nitrogen-containing 6-membered ring; R A represents an aryl group, a heterocyclic group, or an —(R 1 ) r —(R 4 ) m group; X represents an aryl group; wherein, when R A represents an —(R 1 ) r —(R 4 ) m group, R 1 represents a methylene group, a methine group, or a carbon atom; r represents an integer of 1 to 30, and R 1 s may be the same or different independently, when r is 2 or more; R 4 represents a substituent except for a hydrogen atom; m represents an integer of 1 to 30, and R 4 s may be the same or different independently, or R 4 s may be combine together to form a multiple bond, or alternatively R 4 s may bond with each other to form a ring, when m is 2 or more; and the —(R 1 ) r —(R 4 ) m group does not represent a straight-chain alkyl group; R 5 and R 6 each represent a hydrogen atom or a substituent, or R 5 and R 6 may bond with each other to form a ring; R 7 represents a hydrogen atom or a substituent; n represents 0 (zero) or an integer of 1 to 4, with the proviso that R 7 s may be the same or different independently, or R 7 s may bond with each other to form a condensed ring, n is 2 or more; or R 7 may bond with R 5 or R 6 to form a condensed ring, n is 1 or more.
