    摘要： An ink composition is disclosed herein. The ink composition includes from about 5 wt % to about 25 wt % of a co-solvent; from about 0.025 wt % to about 0.2 wt % of i) a chelating agent represented by formula 1, wherein R′ is a carboxylic acid functional group or a carboxylate salt functional group and n>2; ii) a chelating agent represented by formula 2:, wherein R is a carboxylic acid functional group or a carboxylate salt functional group, m is greater than or equal to 1, x is greater than or equal to 2, y is greater than or equal to 1, and z is greater than or equal to 2; iii) a chelating agent represented by formula 3, wherein any of r, s, t, or u is a sulfonic acid functional group or a sulfonate functional group; or iv) combinations of any of i, ii, and iii. The ink composition also includes a balance of water.

    摘要： Compositions, systems, and methods for ink-jet printing having improved black to color bleed control, reduced wicking, and/or reduced halo are described. The composition can include a functionalized carbon pigment dispersed in an ink vehicle. The carbon pigment includes functional groups chemically attached thereto. Suitable functional groups includes an aromatic ring structure having multiple carboxyl groups (or salts thereof) attached to the aromatic ring structure, wherein at least two of the multiple carboxyl groups are positioned on adjacent carbon atoms of the aromatic ring structure.

    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.
