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.

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： Color bleed (the invasion of one color into another on the surface of the print medium) using ink-jet inks is controlled by employing either high molecular weight polymers that exhibit a reversible gelling nature with heat or certain amine oxide surfactants that undergo sol-gel transitions. The inks of the invention further include a vehicle and a dye. The vehicle typically comprises a low viscosity, high boiling point solvent and water. Certain high molecular weight polymers, under the correct solution conditions, can form gels which can be subsequently melted by heating of the gel. When the melted gel is cooled, it will then reform into a gel. The viscosity of an ink employing such a gel can be reduced to a viscosity low enough to permit jetting from the print cartridge. After leaving the print cartridge, the melted gel will again reform into a highly viscous gel to immobilize the droplet of ink and prevent its migration on the media. Therefore, two drops of different colors, when printed next to one another will thus be inhibited from migrating or bleeding into one another.

摘要： A method for controlling color bleed between adjacent multi-color ink regions on a print medium is disclosed. Color bleed involves the migration of color agents between adjacent zones in a multicolored printed image on a print medium. A first composition containing a gel-forming species and a color agent is brought into contact on a region of the print medium with a second composition having a color agent and a gel-initiating species or chemical conditions which bring about gelation. In alternative embodiments, the print medium may be pretreated with either a gel-initiating species or a gel-forming species (with no colorant), followed by treatment with a gel-forming species or gel-initiating species (with colorant), respectively. The formation of the gel upon the print medium impedes the movement of the color agent or agents and thus reduces the color bleed between adjacent zones.

摘要： A method for controlling color bleed in multi-color thermal inkjet printing systems. Color bleed involves the migration of coloring agents between adjacent zones in a multi-color printed image on a substrate. To control color bleed between any two ink compositions in a multi-ink system, at least one of the ink compositions will contain a precipitating agent (e.g. a multi-valent metal salt). The precipitating agent is designed to react with the coloring agent in the other ink composition of concern. As a result, when the two ink compositions come in contact, a precipitate is formed from the coloring agent in the other ink composition which prevents migration thereof and color bleed problems. This technique is applicable to printing systems containing two or more ink compositions, and enables distinct multi-color images to be produced without the problems normally caused by color bleed.
摘要翻译：一种用于控制多色热喷墨打印系统中的色彩渗色的方法。颜色渗色涉及着色剂在基板上的多色印刷图像中的相邻区域之间的迁移。为了控制多油墨系统中的任何两种油墨组合物之间的色彩渗色，至少一种油墨组合物将含有沉淀剂（例如多价金属盐）。沉淀剂被设计成与所关注的另一种墨水组合物中的着色剂反应。结果，当两种油墨组合物接触时，由另一种油墨组合物中的着色剂形成沉淀物，其防止其迁移和着色问题。该技术适用于含有两种或更多种油墨组合物的印刷系统，并且能够产生不同的多色图像，而不会出现通常由颜色渗色引起的问题。
