<p>The present invention provides an ink composition comprising a colorant, a solvent, a surfactant, and a defoaming agent. The defoaming agent has a structure of Formula R 1 - X -( CH 2 CH 2 O ) m -( CH CH 3 CH 2 O ) n - R 2 (I), in which, X is selected from the group consisting of COO, O, S, R 3 -N and R 4 (R 5 )-C; R 1 , R 2 , R 3 , R 4 , and R 5 are each independently selected from the group consisting of a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aryl group and a substituted or unsubstituted aralkyl group; m is an integer from 0 to 100; and n is a natural number from 1 to 100. The ink composition according to the exemplary embodiment exhibits low foaming properties in order to flow smoothly and has a good initial discharge capacity and less ink bleeding so that it is possible to achieve a high print quality during printing, and an ink cartridge including the same.</p> |
