Poly(styrene-co-butyl methacrylate) and poly(styrene-co-butyl acrylate) latices were prepared by emulsion polymerization with alkali-hydrolyzable and nonhydrolyzable cationic emulsifiers and were used as a dispersant and binder for waterborne carbon black (CB) paint. CB was dispersed in the latex solutions and then coated on filter paper pretreated with dilute aqueous Na 2 CO 3 under mild conditions. The styrene (St)-rich rigid copolymer latices easily dispersed the CB but fixed a little amount of the pigment on the paper surface. In contrast, the methacrylate-and acrylate-rich soft latices tended to increase the adhesibility on it. We also demonstrated that the hydrolyzable-emulsifier-containing latices always had a higher adhesibility than the nonhydrolyzable-emulsifiercontaining ones. Thus, the hydrolyzable-emulsifier-containing latices with an appropriate St content had the highest paintability, rapid adhesion, quick drying, reduced fading, superior fastness, and so on.
