Abstract
Provided is an ink composition including a colorant; a solvent; a surfactant; and an oxygen absorber of a hetero ring compound and a hydroxylamine-based compound. The oxygen absorber lowers a concentration of oxygen dissolved in the ink composition and maintains a low level even when the ink composition is in a high-temperature condition. Thus, gas is substantially not generated and bubbles are not formed. The ink composition can be stably ejected during high-speed printing.
