| titleOfInvention | Composite Particles and Method of Making the Same |
| abstract | A composite particle is provided comprising a base particle and a plurality of hydrophilic oligomeric groups extending from an outer portion of the base particle, wherein the base particle comprises a crosslinked polyurea and at least one of a pigment and a dye. The crosslinked polyurea may form a network across the base particle. The method for preparing composite particles comprises the steps of providing either a solution containing a dye or a dispersion containing a pigment to a water-dispersible polyfunctional isocyanate dissolved in a water-miscible solvent, forming an emulsion of the solution/dispersion in water , agitating the emulsion while the polyfunctional isocyanate is converted to the crosslinked polyurea, and separating the composite particles containing the crosslinked polyurea and dye/pigment from the emulsion. |
