Composite particles and method for making the same |
| abstract |
A composite particle is provided that includes a base particle and a plurality of hydrophilic oligomeric groups extending from an exterior portion of the base particle, the base particle including a cross-linked polyurea and at least one of a pigment and a dye. The cross-linked polyurea may form a network throughout the base particle. A method of making the composite particle includes providing either a solution containing a dye or a dispersion containing a pigment in 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 into a cross-linked polyurea, and separating the composite particle containing the cross-linked polyurea and the dye/pigment from the emulsion. |
