摘要： An ink composition for ink-jet printers is provided which includes a chromophore, a solvent, a co-solvent, a humectant, a surfactant, a viscosity adjuster and an additive. The additive is a nitrogen-containing heterocyclic compound. This nitrogen-containing heterocyclic compound has the hydroxy groups which improve miscibility with water, thereby preventing clogging of nozzles during use. The present invention increases the affinity for dye used as a chromophore and for the hydroxy groups of paper after discharging of ink, which allows the chromophore to easily fix on the paper, thus enhancing smearfastness of the ink composition after printing.
