摘要： An organic acid component is employed in a first ink-jet ink composition to reduce the pH differential required to render insoluble the pH-sensitive colorant of a second encroaching ink-jet ink composition. By inducing the precipitation of the pH-sensitive colorant, migration of the colorant is inhibited, thereby substantially reducing bleed between the pH-sensitive ink and the ink containing the organic acid (the "target" ink). The organic acid component is employed at a concentration ranging from about 0.25 to 20 wt % and may be represented by such as acids as polyacrylic, acetic, glycolic, malonic, malic, maleic, ascorbic, succinic, glutaric, fumaric, citric, tartaric, lactic, sulfonic, ortho-phosphoric acid, derivatives thereof. Without the organic acid component, a pH differential on the order of at least 4 and more likely 5 units must exist between the pH-sensitive ink and the target ink to substantially eliminate bleed. By employing an organic acid in the practice of the invention, a pH differential on the order of only 1 to 3 units may be required. Therefore, assuming the pH-sensitive ink has a pH of about 8, the pH of the target ink could be as high as 7 in the practice of the invention as opposed to a pH of about 3 in the absence of an organic acid component.
摘要翻译：在第一喷墨油墨组合物中使用有机酸组分以降低使第二侵入式喷墨油墨组合物的pH敏感着色剂变成不溶性所需的pH差异。通过诱导pH敏感着色剂的沉淀，着色剂的迁移被抑制，从而大大减少了pH敏感性油墨和含有机酸的油墨（“目标”油墨）之间的渗色。有机酸组分的使用浓度范围为约0.25至20重量％，可以由诸如聚丙烯酸，乙酸，乙醇酸，丙二酸，苹果酸，马来酸，抗坏血酸，琥珀酸，戊二酸，富马酸，柠檬酸，酒石酸，乳酸，磺酸，正磷酸，其衍生物。没有有机酸组分时，pH敏感油墨和目标油墨之间必须存在大约至少4个数量级，更可能5个单位的pH差异以基本上消除渗色。通过在本发明的实践中使用有机酸，可能需要大约1至3个单位的pH差。因此，假设pH敏感性墨水的pH值约为8，与实施例1相比，在不存在有机酸成分的情况下，目标油墨的pH值可高达7。

摘要： A method of printing an ink jet ink on a print medium is provided, wherein a printed image is formed that is both waterfast and smearfast. The method employs a water-insoluble colorant and comprises: (a) providing an aqueous-based ink containing at least one disperse, sublimation dye and at least one dispersant for dispersing the dye; (b) jetting the ink onto the print medium to form an intermediate printed image; and (c) subjecting the print medium to a combination of heat and pressure for a period of time to convert the intermediate printed image to the waterfast and smearfast printed image. The temperature is high enough to cause the disperse, sublimation dye to disintegrate and diffuse into the print medium, thereby diffusing the coloring agents out of the dispersant “shell” around the dye particulate and recondensing in the same place as solvent dyes, free of the dispersant. Solvent dyes are insoluble in water. Thus, the recondensed solvent dyes on the substrate are essentially impervious to water, and the printed ink attains a waterfastness and smearfastness not previously achieved in aqueous thermal ink jet printing.

摘要： An ink transfer sheet and method for using the same. The transfer sheet includes a backing layer, a release layer on the backing layer, and an ink receiving layer on the release layer. The ink receiving layer contains a quaternary ammonium salt thereon or impregnated therein. To use the transfer sheet, an ink containing an anionic coloring agent is applied to the ink receiving layer, preferably using thermal inkjet methods. Thereafter, the transfer sheet is positioned on a fabric substrate. Heat is applied to the sheet which causes the release layer and ink receiving layer to adhere to the substrate. The backing layer is then detached from the release layer leaving the release and ink receiving layers (with the printed image thereon) on the substrate. This process transfers the image to the fabric substrate, with the image being stabilized by interactions between the quaternary ammonium salt and anionic coloring agent.

摘要： A method of printing an ink onto a print medium is provided. In the method, two inks are employed, a first ink that includes at least one water-soluble color dye that has a first charge, e.g., anionic, and a second ink that includes at least one black pigment that has a second and opposite charge, e.g., cationic. The method comprises: (a) providing the first ink, which contains at least one water-soluble, anionic color dye and at least one surfactant; (b) providing the second ink, which contains at least one cationic black pigment; (c) printing in a first pass across the print medium the first ink; (d) printing the second ink over the first ink, totally covering and overlapping the first ink, whereby the cationic black pigment(s) reacts with the anionic color dye(s) to form an insoluble complex on the print medium, and the surfactant draws the vehicle into the print medium, thereby improving print speed, print quality, bleed, and waterfastness of the ink. A printed ink set is also provided. The printed ink set comprises the cationic black pigment-based ink printed over the anionic color dye-based ink.
