Abstract: The present invention relates to inkjet ink compositions that take advantage of solvent mixtures containing an ester, a ketone, and optionally an alcohol, in order to provide ink compositions that have suitable qualities for inkjet printing. Preferred ink compositions include a C1-C3 alkyl ester of C1-C3 carboxylic acid, a C3-C7 ketone, and optionally a C2-C3 alkyl alcohol.

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: A solvent-based inkjet ink composition for inkjet printing includes at least 50 weight percent solvent, a colorant, a humectant, from 0.3 weight % to 8 weight % of a binder resin, and not more than 5 weight percent water. The ink composition is compatible with components of a thermal ink jet printer.

Abstract: Method and systems are provided for decorating product packaging. A substrate suitable for product packaging to a thermal printer, such as a thermal transfer printer. A decoration is selected for printing on the substrate. The thermal printer is operated to print at least a portion of the decoration on the substrate.

Abstract: Disclosed is an ink jet ink composition that forms indelible images on porous or semiporous substrates. The ink composition comprises a liquid carrier, a first colorant that is soluble in the carrier but insoluble or substantially insoluble in water, and a second colorant composition comprising a pigment, the second colorant composition being dispersible in the carrier. The second colorant composition is insoluble or substantially insoluble in the carrier. The images are difficult or impossible to remove or wash out by the use of aqueous and/or nonaqueous liquids.

Abstract: Disclosed is an ink composition which is suitable for ink jet printing and comprising an organic solvent, for example, methanol, a water-soluble resin, a water-soluble dye, and optionally a surfactant, wherein, if water is present, it is present in an amount less than 50% by weight of the ink composition. The ink composition is suitable for printing messages on substrates such as diaper outer liner fabrics. The printed messages are removed upon contact with water or urine or other aqueous body fluid, thereby providing an indication of diaper wetness.
