Provided is a compound represented by Formula (1) as a novel compound with a specific structure derived from a xanthene structure, having a specific triazine unit in a side chain thereof, which further improves performances of a printed matter according to image fastness such as ozone resistance, light fastness and moisture resistance have been further improved than the compounds in the related art, and imparts a printed matter having excellent print concentration. In Formula (1), R 0 to R 3 each independently represent a hydrogen atom or a substituent. R 0 and R 1 , R 0 and L, or R 1 and L may be combined with each other to form a ring.
L represents a single bond or a divalent linking group.
D represents a residue in which n hydrogen atoms are removed from a compound represented by Formula (2).
n represents an integer of 1 or more. However, when n represents an integer of 2 or more, a plurality of R 0 's to R 3 's and L's may be the same or different. In Formula (2), R 4 to R 24 each independently represent a hydrogen atom or a substituent. However, the compound represented by Formula (1) has at least one ionic hydrophilic group. |
