Abstract

Process for the production of alkyd resins having a final acid number of not more than 40 and a high --OH number for use in water lacquers. The resins of the invention can be made up with the aid of aminoalcohols containing more than two hydroxyl groups into optically clear water lacquers which are distinguished both by their lack of environmental problems and also by their advantageous lacquer properties.
