摘要： In accordance with the invention inks suitable for use in ink-jet printers and method for formulating the same are provided. More particularly, inks comprising the present dyes and buffers exhibit excellent color performance and lightfastness across a range of media. Furthermore, the inks enable good reliability in an environment having a relatively high concentration of precipitating agents. This reliability enables the use of precipitation bleed control mechanisms.

摘要： Wet cockle is minimized in aqueous-based, thermal ink-jet inks by adding to the ink at least one water-soluble substance, such as a solvent or salt, having a molecular weight of less than 200 grams/mole in an amount sufficient to reduce the mole fraction of water to a maximum value of about 0.5. Addition of the substance reduces wet paper cockle to a value that is less than the distance between the thermal ink-jet pen and the paper, thereby preventing a crash condition between the paper and the pen.
摘要翻译：通过向油墨中加入至少一种分子量小于200克/摩尔的水溶性物质，例如溶剂或盐，使水性基础的热喷墨油墨最小化，其量足以将水的摩尔分数降低到最大值约0.5。添加该物质可以将湿纸烟囱减小到小于热喷墨笔和纸之间距离的值，从而防止纸和纸笔之间的碰撞状况。

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。

摘要： Inks are provided comprising (a) at least two dyes corresponding to the formula ##STR1## wherein W is COOH,X is H, or COOH,Y is H, COOH, or SO.sub.3 H,Z is H, COOH, or SO.sub.3 H, andR is H, CH.sub.2 COOH, or CH.sub.2 CH.sub.2 COOH;with the proviso that there are at least two COOH groups and that the number of COOH groups is equal to or greater than the number of SO.sub.3 H groups, and (b) a solvent which may be water or a mixture of water and a water-soluble organic solvent provide excellent waterfast prints on paper. The inks preferably have a pH from about 7 to about 9.5. Also preferably, a phosphate is added to reduce kogation and a metal chelating agent is added to further reduce nozzle clogging.

摘要： An ink can be substantially invisible under most lighting conditions, and only visible when excited by UV energy having a wavelength specific to the colorant. The ink can include a liquid vehicle and a fluorescent colorant. The fluorescent colorant can have an average particle size of less than about 200 nm. Such ink can be configured as an ink-jet ink.

摘要： A print head for ink-jet printing including an orifice plate with an intermediate layer of reinforcement material bonded thereto, an ink barrier layer, and an adhesion promoter located between the intermediate layer and the barrier layer. The adhesion promoter bonds the intermediate layer to the barrier layer. Exemplary adhesion promoters include organosilane compositions, polyacrylic acid, polymethylacrylic acid, and mixtures thereof. Representative intermediate layers include oxidizable metals (e.g. chromium, tantalum, and mixtures thereof) and silicon-containing compositions (e.g. silicon dioxide, silicon nitride, silicon carbide, and mixtures thereof). In a process for making a print head, an adhesion promoter is applied to the orifice plate/intermediate layer combination which is thereafter bonded to the barrier layer using the adhesion promoter. All of these components are secured together through the application of pressure and heat.
