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: 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.

Abstract: A thermal ink jet ink composition includes one or more volatile organic solvents, wherein the one or more volatile organic solvents comprise a solvent selected from C1-C4 alcohols, C3-C6 ketones, C3-C6 esters, C4-C8 ethers, and mixtures thereof. The one or more volatile organic solvents are present in an amount at least 60% by weight of the ink composition. The ink composition includes one or more binder resins present in an amount from 1% to 10% by weight of the ink composition, and one or more dyes. If water is present, it is present in amount less than 5% by weight of the ink composition. The ink composition includes less than 2% by weight of any humectant and/or wetting agent with a relative evaporation rate less than 0.3. The ink composition is suitable for use in a thermal ink jet printer.
