Bleed alleviated aqueous pigment dispersion-based ink-jet ink compositions |
摘要 |
<p>Bleed control and fast dry times are achieved in aqueous pigment dispersion-based ink-jet ink compositions by formulating the ink compositions to comprise at least one aqueous pigment dispersion and a microemulsion comprising at least one water-insoluble organic compound, at least one hydrotropic amphiphile, and water. The hydrotropic amphiphile is present in the microemulsion in an amount sufficient to solubilize the water-insoluble organic compound in water. By employing a microemulsion-based vehicle formulated in accordance with the invention, the present aqueous pigment dispersion-based ink-jet ink compositions are bleed-alleviated and fast-drying when printed onto a print media so that the throughput of an ink-jet printer may be increased.</p> |
