    摘要: A method comprising forming a water-in-oil emulsion of an aqueous phase comprising discrete water-insoluble particles an an aqueous solution of a water-soluble polymerizable monomer, polymerizing said monomer, phase-inverting the water-in-oil emulsion to an oil-in-water emulsion, removing the oil phase from the phase-inverted emulsion to form an aqueous latex, adding to the latex an ethylenically unsaturated polymerizable second monomer, and polymerizing said second monomer to produce hydrophobic resin-encapsulated water-insoluble particles; and the resulting encapsulated particles.
