Inkjet ink binder and inkjet ink composition

摘要

An inkjet ink binder including an aqueous dispersion of polymer particles, the polymer comprising as polymerized units from 3 to 20 wt.% monoethylenically unsaturated acid monomer, based on polymer weight, and having a glass transition temperature (Tg) in the range of from -40 DEG C to 120 DEG C, and the polymer particles having a volume average particle diameter as measured by dynamic light scattering of at least 35 nanometers greater than the weight average particle diameter as measured by capillary hydrodynamic fractionation is provided. An inkjet ink including the inkjet ink binder is also provided.
