    摘要： An inkjet ink for printing onto a print medium is provided. The inkjet ink evidences minimal tail breakup and improved drop trajectory, thereby evidencing improved print quality. The minimal tail breakup and improved drop trajectory are achieved by adding at least one surface active additive to the ink to provide the ink with a surface tension of at least 35 dyne/cm and a contact angle (with an orifice plate comprising KAPTON, an aromatic polyimide) of about 35 to 65 degrees.

    摘要： The present invention relates to ink-jet ink compositions that comprise macromolecular chromophores having functional groups covalently attached for water solubility. Moreover, the MMCs have polymer chains covalently attached to the pigments by nucleophilic substitution to provide enhanced smearfastness, enhanced print quality, improved bleed control, and improved resistance to water when applied to the media. These inks have good viscosity and surface tension, are more soluble in organic solvents and are, therefore, useful in ink-jet printing, including thermal ink jet printing, piezoelectric ink jet printing, and continuous ink jet printing.

    摘要： The properties of ink-jet inks containing a colorant (pigment, macromolecular chromophore, or dye) are improved by adding thereto an additive, specifically, one or more polymers derived from unsaturated surfactants. The unsaturated surfactant(s) has at least one carbon-carbon double bond (C═C). The polymer may be simply an polymer of the unsaturated surfactant. Alternatively, the polymer may be co-polymerized with one or more vinyl monomers or one or more polymers based on the vinyl monomers may be mixed with the unsaturated surfactant polymer. The vinyl monomer(s) or polymer(s) are used to adjust or “tweak” the properties of the resultant polymer. For example, the more hydrophobic the polymer or the higher its molecular weight, then the greater the water-fastness afforded the ink-jet ink. The polymeric additive of the invention improves bleed control, water-fastness, and smear-fastness of ink-jet inks, particularly thermal ink-jet inks.
