Abstract
The present invention is directed to latex particulates having a greater concentration of acid at their surfaces than at their cores. A method of making such particulates can comprise copolymerizing an acidic monomer with a non-acidic monomer so as to yield a copolymer chain having more acidic monomer at one end than at the other.
