Abstract

Abstract Translated from German Zur Aktivierung von Substratoberflächen für die stromlose Metallisierung eignen sich hervorragend Komplexverbindungen der Elemente der 1. und 8. Nebengruppe des Periodensystems in den Oxidationsstufen 1-4 mit a, ß-ungesättigten Ketonen der Formel worin R, und R. Alkyl, Cycloalkyl oder Aryl und R 2 und R 3 Wasserstoff oder Alkyl bedeuten, da sich diese Komplexe durch eine hohe Lagerstabilität auszeichnen. Bevorzugt sind die Palladiumkomplexe von Buten-3-on-2 und Hepten-3-on-2. For the activation of substrate surfaces for electroless metallization, complex compounds of the elements of the 1st and 8th subgroup of the periodic table in the oxidation states 1-4 with a, β-unsaturated ketones of the formula are outstandingly suitable wherein R, and R. alkyl, cycloalkyl or aryl and R 2 and R 3 are hydrogen or alkyl, since these complexes are distinguished by a high storage stability. The palladium complexes of buten-3-one-2 and hepten-3-one-2 are preferred.
