Abstract
Abstract A process for the production of water-soluble alkyd resins and to protective coating compositions made therefrom. The resins are prepared by reacting polycarboxylic aliphatic or aromatic acids, anhydrides or mixtures thereof having four to 20 carbon atoms with a polyhydric aliphatic or cycloaliphatic alcohol of two to 10 carbon atoms to give a reaction product having an acid number of 50-250. The product is then reacted with N,N-bis( 2hydroxyalkyl)-2-hydroxy-ethoxyacetamide to give the alkyd resins.
