A fluorescent ink composition is provided to prevent a clogging phenomenon of a nozzle because the ink composition is kept in a proper viscosity range at room temperature. A fluorescent ink composition comprises: a solvent including 45-55wt% of benzyl alcohol, 15-35wt% of cyclohexane, 10-15wt% of diethylene glycol monobutyl ether acetate, and 10-20wt% of methanol; and a fluorescent dye to be added to the solvent in a ratio of 1-3wt% based on the total weight of the solvent and fluorescent dye. The fluorescent ink composition further comprises 1-3wt% of a fluorescent brightening agent based on the total weight of the fluorescent ink composition. |
