A dye having a structure represented by general formula (1A). [In general formula (1A), A represents an atom group required, together with a carbon-nitrogen bond, for the formation of a ring; either Y 1A and/or Y 2A represents an acidic group, provided that when both Y 1A and Y 2A represent an acidic group, Y 1A and Y 2A may be the same as or different from each other, and when one of Y 1A and Y 2A represents an acidic group, the other represents an electron-withdrawing group; D represents a dye residue; n represents an integer of 1 or greater; L represents a single bond or a bivalent linkage group; and Y 3A represents an acidic group.] |
