Abstract: An alkyd resin modified by radicals of at least one drying fatty acid or the isomerization or conjugated derivative thereof, containing urethane groups and having an acid number of 30 to 70 and a hydroxyl number of 20 to 120 may be prepared by reacting an alkyd resin modified by radicals of at least one drying fatty acid or derivative thereof and containing free OH groups with a mono- or polyisocyanate. The alkyd resin reacted with the isocyanates may have acid and hydroxyl numbers greater than those desired. Alternatively, a first alkyd resin modified by radicals of at least one drying fatty acid and having an acid number below that desired and a hydroxyl number above that desired in the final product is reacted with a mono- or polyisocyanate to obtain a second alkyd resin containing urethane groups which is then reacted with a dicarboxylic acid anhydride. A second alternative method is to react the drying fatty acid modified alkyd resin having a hydroxyl number higher than that desired with a dicarboxylic acid anhydride to obtain a partially esterified alkyd resin which is reacted with a mono- or polyisocyanate. The alkyd resin containing urethane groups may be at least partially neutralized with ammonia and/or an amine and/or an alkali. The salt may be used in an aqueous varnish composition. In an example, pentaerythritol, linseed fatty acid and phthalic anhydride are esterified, followed by the addition of further phthalic anhydride. The resin dissolved in dimethylformamide is reacted with toluylene diisocyanate, the product neutralized with ammonia and diluted with water to form a lacquer.
