(57) [Problem] To develop a red fluorescent material with improved solubility in a solvent containing water and an ink composition using the same. A red fluorescent material represented by the following general formula (1). Embedded image (In the formula, X represents an aromatic ring or a heterocyclic group which may have a substituent, Y represents a fluorinated hydrocarbon group having 1 to 10 carbon atoms, and R 1 to R 4 each independently represent at least one hydrophilic group. An alkyl group, an aralkyl group, or a hydrogen atom, which may have a substituent, and may have a substituent, and may be bonded to each other to form a ring; and a composition containing the same. |
