Description
Die vorliegende Erfindung betrifft eine Lösung zum Akti- Komplex reagiert und diesen so in der Lösung stabilisiert, ohne vieren von metallischen und nichtmetallischen Oberflächen zur mit seinem Verhalten bei der aktivierenden Behandlung von nachfolgenden stromlosen Metallabscheidung auf diesen und Oberflächen zu interferieren. The present invention relates to a solution to react to the Akti complex and thus stabilize it in the solution without four metallic and non-metallic surfaces to interfere with its behavior in the activating treatment of subsequent electroless metal deposition on these and surfaces.
Verfahren zu deren Herstellung. Aus der CH-PS 564 094 sind 65 Lösungen bekannt, die eine Doppelmetallkomplex-Verbindung Beispiel 1 Process for their production. From CH-PS 564 094 65 solutions are known which are a double metal complex compound Example 1

50,0 ml/1 Salzsäure (37%), 50.0 ml / 1 hydrochloric acid (37%),
2,5 g/1 Zinn(II)chlorid (dihydrat) und H2O enthält, um 1 Liter Lösung herzustellen. Contains 2.5 g / 1 tin (II) chloride (dihydrate) and H2O to make 1 liter solution.
Wird diese Lösung unstabil gelassen, so scheidet sich nach einiger Zeit metallisches Palladium ab. Wird dieser Lösung 5 jedoch 20 g/1 Hydrochinon zugesetzt, so tritt vollständige Stabilisierung ein. If this solution is left unstable, metallic palladium separates out after some time. However, if 20 g / 1 hydroquinone is added to this solution 5, complete stabilization occurs.

The palladium chloride is expediently added as a corresponding amount of a palladium chloride solution in hydrochloric acid. After briefly boiling the solution (about 2 minutes) and cooling, 10 g / 1 hydroxylamine is added as sulfate and the solution is heated to boil for a further 5 minutes. 20th
