Abstract
Colloidal size particles of an organic solid such as a pigment are encapsulated in a hydrophobic addition polymer such as a polymer of styrene by a polymerization process wherein a water-immiscible (hydrophobic) monomer is dispersed in an aqueous colloidal dispersion of the organic particles and subjected to conditions of emulsion polymerization. The resulting encapsulated particles are usefully employed as toners and pigments.
