  • Ink composition for ink-jet printing and ink-jet printing
    Publication number: 20060000387
    Abstract: An ink composition for inkjet printing and ink-jet printing method employing the same. The ink composition comprises a colorant, an aqueous solution medium, and a non-ionic surfactant with HLB not more than 10.6. Compared with an ink including a non-ionic surfactant with HLB of more than 10.6, the ink composition of the present invention has improved smear resistance, thus enhancing inkjet printing quality.
