AQUEOUS POLYESTER EMULSIONS AND THE USE THEREOF FOR THE PRODUCTION OF PARTICULARLY THIN-LAYER COATINGS

摘要

Paraffin-containing monomer-free aqueous emulsions of a mixture comprising two unsaturated polyesters, of which one contains .beta..?-unsaturated ether groups, but no co-condensed res dues of higher polyalkylene glycols, whilst the other contains co-condensed residues of higher polyalkylene glycols and monofuncitonal alcohols and/or carboxylic acids, but no .beta..?-unsaturated ether groups, are eminently suitable for the production of extremely thin-layer coatings without levelling faults.
