Patent ID: 8202921

Claim:
An aqueous alkyd resin emulsion containing a resin obtained by reaction of a composition comprising: 10 to 35 wt. % of at least one polyhydric alcohol having at least two hydroxyl groups which has a molecular weight of at least 60 g/mol, 3 to 15 wt. % of at least one polyetherpolyol having a molecular weight of 400 to 8000 g/mol, 10 to 60 wt. % of at least one monobasic carboxylic acid, and 10 to 40 wt. % of at least one polybasic carboxylic acid having at least two carboxyl groups or its anhydride, wherein the resin obtained by the reaction further comprises at least one nitrogen-containing basic group which is provided by a molecule which has at least one nitrogen-containing basic group or a molecule which has at least one protected nitrogen-containing basic group, and which has a molecular weight of at least 100 g/mol, wherein the nitrogen-containing basic group is attached to the resin by a covalent bond.
