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.

摘要： A method is provided for enhancing and accelerating wetting of hydrophobic foams for use as ink reservoirs in ink-jet printer pens. First, the foam is placed in a prewet bath, having already been compressed to expel air. The prewet bath contains an aqueous solution with a low molecular weight alcohol additive, such as n-propanol, ranging in concentration from about 3 to 10 wt. %. Second, the foam is repeatedly compressed and allowed to expand while in the prewet bath, thereby promoting the foam's absorbance of prewetting solution and further improving foam wettability. Finally, the foam is removed from the prewet bath and is compressed to expel excess prewetting solution. The foam retains residual alcohol from the prewet bath that subsequently becomes a constituent of the ink stored in the foam. In addition to improving the wetting process for hydrophobic foam, the alcohol additive prevents orifice plugging within ink-jet pens by becoming a residual constituent of the ink and wetting pen parts through ink usage.
摘要翻译：提供了一种用于增强和加速用于喷墨打印机笔中的墨水储存器的疏水泡沫的润湿的方法。首先，将泡沫放置在已经被压缩以排出空气的预湿浴中。预湿浴包含含有浓度为约3至10重量％的低分子量醇添加剂如正丙醇的水溶液。％。第二，泡沫在预湿浴中反复压缩并允许膨胀，从而促进泡沫的预润湿溶液的吸光度并进一步提高泡沫润湿性。最后，将泡沫从预湿浴中取出并被压缩以排出过量的预润湿溶液。泡沫保留来自预湿浴的剩余的醇，其随后成为存储在泡沫中的油墨的成分。除了改善疏水泡沫的润湿过程之外，醇添加剂通过成为油墨的残留成分并通过油墨使用润湿笔部件来防止喷墨笔中的孔堵塞。

摘要： An ink-jet ink for ink-jet printers is provided, comprising: (a) an aqueous-based vehicle; and (b) an anionic dye complexed with a polyamine in an amount sufficient to form a pH-insensitive, water-soluble, dye:polyamine complex that acts like a cationic dye. Further, a method of converting the anionic dye to the cationic dye for formulating the ink-jet ink having a desired pH is provided. The method comprises adding a sufficient amount of the polyamine to form the dye:polyamine complex. The dye:polyamine complex is a complex of the dye and the polyamine polymer, which is cationic. Consequently, this complex behaves as a cationic dye. These ink-jet inks show remarkable waterfastness on a variety of common office papers and are pH-insensitive and even in some cases, completely pH-independent. These inks are thus stable over a wide pH range. In addition, the ink-jet inks exhibit superior ink-to-ink bleed when printed next to a drop of another color ink which contains an anionic polymer or carboxylated colorant and resist crusting or drying in ink-jet nozzles.
摘要翻译：提供一种用于喷墨打印机的喷墨油墨，包括：（a）水性载体; 和（b）与多胺络合的阴离子染料，其量足以形成像阳离子染料一样起作用的pH不敏感的水溶性染料：多胺络合物。此外，提供了将阴离子染料转化为阳离子染料以配制具有所需pH的喷墨油墨的方法。该方法包括加入足量的多胺以形成染料：多胺络合物。染料：多胺络合物是染料和聚胺聚合物的复合物，其是阳离子的。因此，这种复合物表现为阳离子染料。这些喷墨墨水在各种常见的办公用纸上显示出显着的耐水性，并且pH不敏感，甚至在某些情况下，完全不依赖于pH。因此，这些油墨在宽的pH范围内是稳定的。此外，喷墨墨水在印刷在一滴含有阴离子聚合物或羧化着色剂的另一种彩色墨水上并且在喷墨喷嘴中抵抗结皮或干燥时表现出优异的墨到墨渗色。
