Abstract
Aqueous inkjet ink compositions are provided. In an embodiment, such an aqueous inkjet ink composition comprises water; resin particles; a colorant; and optionally, a wax. The resin particles comprise a polymerization product of reactants comprising a monomer, an acidic monomer, a hydrophilic monomer, a difunctional monomer, and a reactive surfactant. The acidic monomer, the hydrophilic monomer, and the difunctional monomer may be present at an amount in a range of from about 10 weight % to about 30 weight % in the resin particles. Methods of forming and using the aqueous inkjet ink compositions are also provided.
