The introduction of pigmented inks is one reason for the rapid growth of ink jet technology over the last 15 years. Essential for the success of these pigmented inks has been the development of polymeric dispersants to provide a balance of dispersion quality, stability, and pen performance in ink jet devices. The Figure illustrates the ionic and steric stabilization of an aqueous pigment dispersion by a structured dispersant.
