The present is drawn to the use of blocked acid monomers for thenincorporation of highly acidic groups, such as strong acids and multiple acids, onnthe surface of latex particles via emulsion polymerization. In accordance withnthis, a method of forming latex particulates having high charge density surfacesncan comprise the steps of preparing a monomer emulsion including an aqueousnphase and an organic monomer phase, wherein the organic monomer phasenincludes at least one blocked acid monomer; polymerizing the organic monomernphase to form blocked acid latex particulates dispersed in the aqueous phase;nand unblocking the blocked acid latex particulates to form acidified latexnparticulates. |
