摘要

A dye, having a structure represented by formula (1A):
wherein A represents a group of atoms necessary for forming a ring together with the carbon-nitrogen bond; at least one of Y 1A and Y 2A represents an acidic group, in which when they each represent an acidic group, they may be the same as or different from each other, or when only one of them represents an acidic group, the other represents an electron-withdrawing group; D represents a group to give a dye; n represents an integer of 1 or greater; L represents a single bond or a divalent linking group; and Y 3A represents an acidic group.
