    摘要： The present invention provides ink compositions for ink-jet printing. The ink compositions comprise by weight from about 0.1 to 5% by weight of a water-soluble polyurethane; from about 0.1 to 15% by weight of a 1,2-alkyldiol having 5-9 carbon atoms; and from about 0.5 to 6% by weight of a pigment. The present invention also provides a process for printing an image on a print medium that comprises applying an inventive ink composition thereto by means of an ink-jet printer. The present invention further provides ink-jet cartridges containing inventive ink compositions.

    摘要： A waterfast, environmentally friendly ink-jet ink, is disclosed comprising from 1% to 90% by weight of a first humectant selected from the group consisting of glycerol, propanediol, and combinations thereof; from 1% to 25% by weight of a second humectant selected from the group consisting of ethylene glycol, diethylene glycol, propylene glycol, and combinations thereof; from 1% to 20% by weight of a drying agent selected from the group consisting of 1,2-hexanediol, 1,2-pentanediol, and combinations thereof; from 0% to 20% by weight of 2-pyrrolidone; from 0.05% to 10.0% by weight of a waterfastness control dye selected from the group consisting of azo-containing dyes and phthalocyanine-containing dyes; and at least one additional dye present at from about 1.0% to 10.0% by weight. If the waterfastness control dye is an azo-containing dye, such dyes can include Direct Red 227, Direct Red 254, Direct Yellow 86, and Acid Orange 7. Alternatively, if the waterfastness control dye is a phthalocyanine-containing dye, the nickel, copper or aluminum phthalocyanines can be used.
