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 formulain-line-formulae description="In-line Formulae" end="lead"?CH2═C(R1)—CON(R2)(R3)in-line-formulae description="In-line Formulae" end="tail"?wherein R1═H, CH3or C2H5and 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.
