Abstract

Abstract Translated from German Paraffinhaltige monomerfreiewäßrige Emulsionen eines Gemisches zweier ungesättigter Polyester, von denen der eine β, y-ungesättigte Äthergruppen, aber keine einkondensierten Reste höherer Polyalkylenglykole der andere dagegen keine β, γ-ungesättigten Äthergruppen, aber einkondensierte Reste höherer Polyalkylenglykole und monofunktioneller Alkohole und/oder Carbonsäuren enthält, eignen sich hervorragend zur Herstellung extrem dünnschichtiger Überzüge ohne Verlaufsstörungen. Paraffin-containing monomer-free aqueous emulsions of a mixture of two unsaturated polyesters, one of which contains β, y-unsaturated ether groups, but no condensed residues of higher polyalkylene glycols, the other, on the other hand, no β, γ-unsaturated ether groups, but condensed residues of higher polyalkylene glycols and monofunctional alcohols and / or carboxylic acids , are ideally suited for the production of extremely thin-layer coatings without flow disturbances.
