<p>An ink composition including a colorant, a first surfactant including at least one of an ionic surfactant and a zwitter ionic surfactant, in an amount that is less than 150 parts by weight based on 100 parts by weight of the colorant, a second surfactant including a nonionic surfactant, in an amount that is less 20 times the amount of the first surfactant, and water; an ink cartridge including the same; and an inkjet recording apparatus including the ink cartridge. The ink composition can maintain a uniform and stable ink flow in an ink path of a print head of the cartridge by securing an optimum dynamic surface tension and minimizing generation of foam. Additionally, the ink composition can also provide uniform printing quality in continued printing and provide stability of long period of use and storage by preventing formation of missing dots due to prevention of the ink flow or occlusion of a nozzle by foam generated during the ink flow.</p> |
