An aqueous microemulsion-based ink-jet ink composition is provided whichnemploys a second organic solvent that is miscible with both the discontinuous and thencontinuous phase. Specifically, the ink-jet ink composition of the present inventionncomprises at least one dye; and a microemulsion comprising at least one high boilingnwater-insoluble organic compound, at least a second high boiling compound misciblenwith both aqueous and organic phases, at least one amphiphile, and water, wherein thenamphiphile is present in an amount sufficient to solubilize the water-insoluble organicncompound. |
