Abstract
Aqueous inkjet ink compositions are provided. In an embodiment, such a composition comprises water; resin particles; and a colorant; wherein the resin particles comprise a polymerization product of reactants comprising a monomer, an acidic monomer, a multifunctional monomer, and a reactive surfactant, the resin particles having a D(z, ave) of no greater than about 150 nm, a D(v,90) of less than about 200 nm, and a polydispersity index (PDI) of no greater than about 0.050. Methods of forming and using the aqueous inkjet ink compositions are also provided.
