Abstract
Disclosed are aqueous inkjet inks containing a polymeric ink additive as a binder. The binder contains a component capable of interacting with cellulose. Certain heterocycles having similar Hansen solubility parameters as cellulose were incorporated into the polymeric binders. Prints from these inks have better durability and optical properties than similar additives that do not have the components capable of interacting with cellulose.
