    • A method for production of a carboxy terminated dendritic polyester is disclosed. Said process comprises ring opening addition of at least one anhydride of a di, tri or polyfunctional aromatic and/or cycloaliphatic carboxylic acid to at least one hydroxy functional dendritic polyester having a hydroxyl value of at least 50 mg KOH/g. Said ring opening addition is performed at a molar ratio said anhydride to hydroxyl groups of between 0.2 to 1 and 1 to 1 and at a reaction temperature of 130-150 °C. Yielded carboxy terminated dendritic polyester has a glass transition temperature of at least 35 °C. The invention relates in further aspects to a powder coating composition comprising the carboxy terminated dendritic polyester obtainable by said process and the use of said carboxy terminated dendritic polyester in a resin composition.

    • An air drying waterborne resin composition is disclosed. Said resin composition comprises at least one amphiphilic air drying dendritic polymer, at least one non-amphiphilic air drying alkyd resin, at least one drier initiating and/or promoting autoxidation, and water, and optionally at least one anionic and/or nonionic surfactant, and/or at least one coalescent agent. Said at least one amphiphilic air drying dendritic polymer is built up from a polyhydric dendritic core polymer having terminal hydroxyl groups and at least one unsaturated carboxylic acid and at least one adduct, obtainable by addition of a monoalkylated polyethylene glycol to a dicarboxylic acid or anhydride and/or a diisocyanate, each bonded to at least one terminal hydroxyl group in said polyhydric dendritic core polymer.
