<p>Paraffin-containing monomer-free aqueous emulsions of a mixture comprising two unsaturated polyesters, of which one contains alpha , gamma -unsaturated ether groups, but no co-condensed residues of higher polyalkylene glycols, while the other contains co-condensed residues of higher polyalkylene glycols and monofunctional alcohols and/or carboxylic acids, but no alpha , gamma -unsaturated ether groups, are eminently suitable for the production of extremely thin-layer coatings without levelling faults.</p> |
