    摘要： A method of forming an aqueous dispersion of particles of zinc stearate includes the steps of forming a mixture of at least one surfactant and water, heating the mixture to a temperature of from about 40° C. to less than a melting temperature of zinc stearate, adding a metal-containing stearate to the mixture under agitation, adding to the mixture a solution of a zinc salt in water, whereby upon inclusion of both the metal-containing stearate and the zinc salt in the mixture, the zinc salt reacts with the metal-containing stearate to form the particles of zinc stearate, continuing the heating and agitation following completion of the latter of the adding of the solution of zinc salt or the adding of the metal-containing stearate to continue the reaction, and cooling to obtain the aqueous dispersion of particles of zinc stearate. The method forms a stable aqueous dispersion of nanometer sized zinc stearate particles particularly useful in coating toner particles.
