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.

Abstract: The invention relates to an airdrying resin suitable for a coating composition characterized in that the resin is a polyesteramide prepared from: A) at least one anhydride chosen from the list containing succinic, glutaric, citraconic, itaconic or maleic anhydride or a combination of any of them, and B) at least one alkanol-amine, and C) at least one fatty acid, wherein the fatty acid is incorporated in the resin in an amount equivalent to an oil- length between 15 and 40%. This airdrying resin is both water- and solvent-soluble, having a combination of properties desirable for different types of applications. The invention relates also to a method for preparing such a polyesteramide resin, to a composition comprising at least one polyesteramide resin and a method for preparing such a composition, to a substrate fully or partially coated with this composition, a method for curing the coated substrate, the cured and coated substrate and the use of resin in various applications.
