Editor’s Note: “A Novel Pigment Dispersant and Surfactant For Radiation Curable Waterborne Ink Jet Inks” was presented at NIP 19. Reprinted with permission of IS&T: The Society of Imaging Science and Technology. The development of waterborne radiation curable ink formulations for ink jet applications is challenged by the need for hydrolytic stability. Most conventional waterborne inks are formulated in the basic pH range (pH ≥ 8). In this case, stable waterborne pigment dispersions are form...
