The styrene-butadiene based anionic and amphoteric latices were prepared and then the flow and electrokinetic behavior of these latices were evaluated. The interaction of these latices with pigment particles and base paper were also determined. The interaction of three component system consisting of amphoteric latex, anionic latex and clay particles was also examined. The effect of the difference of anionic and amphoteric groups on the coating color properties, coating layer structure and the printability are presented. Based on a variety of component systems having ionic latices, the role of ionic groups of latices in a variety of phenomena in coating process, such as the control of binder migration using amphoteric latex-based was color discussed in detail.
