  • Inkjet ink composition
    Patent number: 7381753
    Abstract: An inkjet ink composition having a binder including an aqueous dispersion of polymer particles, the polymer including, as polymerized units, (a) from 0 to 1 wt. % monoethylenically unsaturated acid monomer, based on polymer weight; and (b) monomer of the formula CH2?C(R1)—CON(R2)(R3) wherein R1?H, CH3 or C2H5 and R2 and R3 are independently selected from C1-C6 saturated alkyl and cycloalkyl groups; and wherein the total of (a) and (b) is at least 0.1 wt % monomer based on the polymer weight. The binder may be a copolymer of ethyl acrylate and acrylamide. An inkjet ink composition including the inkjet ink binder, a colorant, and a liquid medium is also provided.
    Type: Grant
    Filed: April 14, 2005
    Date of Patent: June 3, 2008

  • Inkjet ink composition
    Patent number: 7354476
    Abstract: An inkjet ink composition having a binder including an aqueous dispersion of polymer particles, the polymer comprising as polymerized units from 3 to 20 wt. % monoethylenically unsaturated acid monomer, based on polymer weight, and having a glass transition temperature (Tg) in the range of from ?40° C. to 120° C., and the polymer particles having a volume average particle diameter as measured by dynamic light scattering of at least 35 nanometers greater than the weight average particle diameter as measured by capillary hydrodynamic fractionation is provided. An inkjet ink composition including the inkjet ink binder is also provided.
