摘要： A solvent system has been found which aids in start-up, drop ejection, decap and high frequency firing above 10 kHz for inks which contain latex polymers. Two solvents work in conjunction with each other: 3-hexyne-2,5-diol and 1,2-octanediol. These two solvents in combination improve printability in latex polymer-containing ink-jet inks. Such ink-jet inks also include one or more pigments and a vehicle comprising at least one organic, water-miscible solvent and water.

摘要： A set of ink-jet inks and method for reducing bleed are provided in which the ink-jet ink is formulated to comprise at least one dye-based ink-jet ink composition and at least one pigment-based ink-jet ink composition, wherein the dye-based ink-jet ink composition includes at least one cationic surfactant and wherein the pigment-based ink-jet ink composition includes at least one negatively-charged dispersant. Bleed control between the dye-based ink and the pigment-based ink is achieved by the formation of a stable interface formed by the interaction of the negatively-charged dispersant and both the cationic and counterion groups of the cationic surfactant.

摘要： 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.
