Abstract: A thermal ink jet ink composition includes one or more volatile organic solvents, wherein the one or more volatile organic solvents are selected from C1-C4 alcohols, C3-C6 ketones, C3-C6 esters, C4-C8 ethers, and mixtures thereof; one or more binder resins; and one or more dyes. The ink composition is suitable for use in a thermal ink jet printer and the ink composition has a slow rate of kogation such that it is capable of being printed at least 10 million drops per nozzle from the thermal ink jet printer before drop weight of the ink composition is reduced by more than 10%.

Abstract: The invention provides stable nucleic acid-tagged ink compositions suitable for printing an ink mark on an object as an identifier or for authentication of goods, and methods of marking an article with such a mark. These ink compositions contain a specific nucleic acid of known length and sequence that can be deposited on an article by inkjet printing or thermal transfer printing to produce a mark, which may be visible or invisible, covert or overt. These ink products are stable and can accurately deliver an amount of nucleic acid tag that can be removed or sampled and analyzed by known DNA analytical methods to detect the specific nucleic acid on the marked article but which cannot be identified without previous knowledge of the nucleic acid sequence in the mark. The invention also provides methods of applying these tagged marks using inkjet printers and printer systems, and the systems for using the tagged ink compositions.

Abstract: A thermal ink jet ink composition include a volatile organic solvent, a binder resin, a dye, a humectant in an amount from 1% to 40% by weight of the ink composition, and an additive for extending the decap time. The additive is present in an amount greater than 0.1% by weight of the thermal ink jet ink composition. The additive is selected from fluorinated surfactants, ionic surfactants, and nonionic surfactants.

Abstract: Embodiment of the present invention relate to a continuous inkjet ink composition which uses a higher order ketone solvent or solvents (ketones having 5 or more carbon atoms) in place or more hazardous solvents such as methyl ethyl ketone and a secondary solvent with a higher derived no effect inhalation level greater than 200 mg/m3 such as ethanol. These ink compositions contain a combination of resins including a cellulose resin and a polyurethane resin or an acrylic resin, with an optional third resin. A colorant (i.e., a dye, preferably a conductive dye) also is included.
