Abstract
Modified cationic latexes are prepared from nonionic or cationic latexes having particles containing chemically bound epoxide groups at or near the particle surface by reacting the latex with a nucleophile such as dimethyl sulfide and an acid such as acetic acid to form a latex having stabilizing onium ions chemically bound to the particle at or near the particle surface.
