An ink composition including a compound having a triester structure that has alternately a hydrophilic group and a hydrophobic group, a coloring agent and a solvent. The compound having the triester structure reduces mobility of the coloring agent and increases adhesion to paper, thereby minimizing bleeding between colors of printed images. The triester compound also improves water fastness of printed images and dry and wet rub fastness to have good colorfastness on paper. In addition, the ink composition improves image quality of printed images and has good long-term storage stability so that it can be widely used in inkjet ink, printing ink, paints, textile printing, paper manufacture, cosmetic manufacture, the ceramic industry and the like.
