Abstract (en)

Coating a substrate with one or more layers, comprises applying coating liquids comprising one or more hydroxyl groups-containing polymers as binders, by curtain coating, where the coating liquid contains no surfactants and a greater amount of at least one organic solvent, and exhibits a boiling point of less than 100[deg] C.

Abstract (de)

Die Erfindung betrifft ein Verfahren zur Beschichtung von Substraten, insbesondere Papieren, mit einer oder mehreren Schichten von insbesondere Polyvinylacetalen oder Polyvinylalkohol mittels Curtain-Coating ohne die Verwendung von Surfactants, wobei die mindestens ein organisches Lösungsmittel enthalten. Die Beschichtungen weisen eine Barriere gegen Öl, Fett und/oder Sauerstoff auf.
