  • Use of perfluorinated compounds as a vehicle component in ink-jet inks
    Patent number: 5919293
    Abstract: An ink-jet ink composition and a method for printing are provided which involve the use of at least one perfluorinated solvent as part or all of the vehicle of the ink-jet ink. The ink-jet ink composition evidences improved bleed control, reduced paper cockle and curl, and reduced dry time upon printing onto a print medium.
