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 <?in-line-formulae description="In-line Formulae" end="lead"?>CH<SUB>2</SUB>-C(R1)-CON(R2)(R3) <?in-line-formulae description="In-line Formulae" end="tail"?> wherein R1=H, CH<SUB>3 </SUB>or C<SUB>2</SUB>H<SUB>5 </SUB>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.
