ABSTRACT:
An ink-jet ink composition is provided which includes at least one primary surfactant and at least one co-surfactant, with the co-surfactant having an HLB at least about 1.5 units higher than that of the primary surfactant. The co-surfactant imparts good wetting and cloud point characteristics to the ink-jet ink composition without sacrificing the bleed control achieved with the use of the low-HLB surfactant. The improvement in wetting and cloud point characteristics achieved in the practice of the invention enables ink-jet printers to effect high print quality in a cost-effective manner. A method for increasing the wettability and cloud point of an ink-jet ink by including at least one co-surfactant having an HLB is also provided.
