INKJET INK COMPOSITION

摘要

An inkjet ink composition having a binder including an aqueous dispersion of polymer particles, the polymer including, as polymerized units, (a) from 0 60 1wt% monoethylenically unsaturated acid monomer, based on polymer weight; and (b) monomer of the formula CH<SUB>2</SUB>=C(R1)-CON(R2)(R3) 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 0.1wt% monomer based on the polymer weight. The binder may be a copolymer of ethyl acrylate and acrylamide. An inkjet composition including the inkjet ink binder, a colorant, and a liquid medium also provided.
