Abstract
An air drying waterborne resin composition is disclosed. Said resin composition comprises at least one amphiphlic 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.
