Patent abstract
A method of improving ink stability. A block co-polymer is added to either an under-/overprinting vehicle or an ink vehicle. The polymer increases chemical interactions between the ink the print media. The under-/overprinting vehicle and the ink vehicle interact through electrostatic interactions while the polymer increases smearfastness by interacting with the print media through non-covalent interactions.
