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. |
