Abstract: There is disclosed a process for preparing organic nano-particles comprising the steps of: (a) preparing a solution comprising an unsaturated polyester and/or a vinyl ester resin and a hydrophobic monomer; (b) dispersing the solution obtained in step (a) in an aqueous phase to form a stable emulsion where the aqueous phase is the continuous phase; and (c) using an initiator to cure the emulsion obtained in step (b) in the presence of a water soluble inhibitor to form a dispersion of nano-particles. The invention further provides organic nano-particles obtainable by the process according to the invention; various uses of said nano-particles; such as in paper, dye, toner and personal care compositions and topical medicaments comprising said nano-particles.
