摘要： Described is a color inkjet printer for optimum bleed prevention in a printer utilizing multiple black and color pens wherein there is provided one print cartridge for dispensing black ink onto the printing medium and at least one print cartridge for dispensing color ink onto the printing medium. The cartridge for dispensing black ink contains an ink with little or no surface active agent while the cartridge for dispensing color ink contains a sufficient amount of surface active agent to reduce bleed between the colors. Moreover, the cartridge for dispensing black ink contains an ink which reacts with at least one and more preferably all inks contained in the cartridge for dispensing color ink. This reaction reduces bleed on images where the black print is adjacent to the color print to an acceptable level without requiring the black ink to contain surface active agents that would lead to inferior quality black text on the plain paper print medium. The reaction may be initiated by pH changes, reaction between the actual colorants, or reaction between one of the colorants and a component in the other ink.
摘要翻译：描述了一种彩色喷墨打印机，用于利用多个黑色和彩色笔的打印机中的最佳防漏，其中提供一个用于将黑色墨水分配到打印介质上的打印墨盒和用于将彩色墨水分配到打印介质上的至少一个打印墨盒。用于分配黑色墨水的墨盒包含具有很少或没有表面活性剂的墨水，而用于分配彩色墨水的墨盒含有足够量的表面活性剂以减少颜色之间的渗色。此外，用于分配黑色墨水的墨盒包含与至少一种更优选与墨盒中包含的用于分配彩色墨水的所有墨水反应的墨水。该反应减少了黑色印刷品与彩色印刷物相邻的图像上的渗色，使其不会黑色墨水含有表面活性剂，这些表面活性剂将导致普通纸打印介质上的劣质黑色文字。反应可以通过pH变化，实际着色剂之间的反应或其中一种着色剂与另一种油墨中的组分之间的反应引发。

摘要： Certain dyes become insoluble under specific and well-defined pH conditions. By forcing a dye to become insoluble on the page, migration of the dye is inhibited, thereby helping to reduce bleed between inks of different colors. The dye is forced out of solution from the ink by contact with another ink having the appropriate pH (either higher or lower than that of the first ink).

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。

The colorant is forced out of solution from the ink by contact with another ink having the appropriate pH (either higher or lower than that of the first ink).

摘要翻译：某些着色剂在特定和明确定义的pH条件下变得不溶。通过强迫着色剂在页面上变得不溶，着色剂的迁移被抑制，从而有助于减少不同颜色的油墨之间的渗色。通过与具有适当pH（高于或低于第一油墨的）的另一种油墨接触，将着色剂从油墨中排出溶液。特别地，将含有颜料的着色剂与pH敏感性分散剂组合的油墨与适当pH的油墨结合使用。

摘要： Silica-based, chemically-bonded porous coatings, synthesized via the reaction of organo silanes with silica, are used as coatings for inkjet image printing. Silica is used as the base material in all cases, due to its favorable chemical properties of the surface, and the favorable pore structure. The silane-silica reaction product substantially retains the original pore structure of the pre-reacted silica. The disclosed embodiments solve the problems in the prior art in that any catalytic activity of the silica surface towards image fade is eliminated by the chemical modification of silica. This improves the image fade and humid fastness properties of the coating.
