Abstract

Abstract Translated from German Die Erfindung hat das Ziel, licht- und UV-empfindliche Fotokopierlacke zur Verfuegung zu stellen, die aufgrund ihrer Zusammensetzung zu Resistbildern mit einer hohen Trockenaetzbestaendigkeit fuehren. Das Ziel wird erfindungsgemaess erreicht, indem ein Fotokopierlack mit einem Gehalt von mindestens 5 Gewichtsprozent p-Cumylphenoleinheiten - bezogen auf den Gesamtfeststoff - hergestellt wird, wobei die p-Cumylphenoleinheiten in der licht- und UV-empfindlichen Komponente und/oder im Bindemittel enthalten sind. The object of the invention is to provide light- and UV-sensitive photocopying lacquers which, owing to their composition, lead to resist images with a high resistance to drying. The object is achieved according to the invention by producing a photocopying varnish containing at least 5% by weight of p-cumylphenol units, based on the total solids, the p-cumylphenol units being present in the light- and UV-sensitive component and / or in the binder.
