3-Sulfo-N-propargyl-pyridmium-bromid vorgeschlagen. Es hat sich jedoch gezeigt, daß der Glanzeffekt dieser Verbindung verhältnismäßig gering ist. Aus diesem Grunde müssen sehr große Mengen dieser Verbindung verwendet werden. Dies ist nicht nur vom wirtschaftlichen Standpunkt aus unerwünscht, sondern führt auch dazu, daß das Bad schnell mit organischen Zersetzungsprodukten verunreinigt wird.3-sulfo-N-propargyl-pyridmium-bromide suggested. However, it has been shown that the gloss effect of this compound is relatively small. Out for this reason, very large amounts of this compound must be used. This is not just dated from an economic point of view undesirable, but also leads to the fact that the bath quickly with organic Decomposition products is contaminated.
Es wurde nunmehr gefunden, daß die obenerwähnten Nachteile dadurch beseitigt werden können, wenn man als primäres Glanzmittel ein spezielles N-Propargylpyridiniumsalz verwendetIt has now been found that the above-mentioned disadvantages can be eliminated if a special N-propargylpyridinium salt is used as the primary brightener
So wird also gemäß der Erfindung ein galvanische N-Propargylpyridiniumsalze als Glanzbildner und sekundäre Glanzmittel enthaltendes Nickelbad vorgeschlagen, das dadurch gekennzeichnet ist, daß das Bad ein N-Propargylpyridiniumsalz der allgemeinen FormelThus, according to the invention, a galvanic Suggested nickel bath containing N-propargylpyridinium salts as brighteners and secondary brighteners, which is characterized in that the bath is an N-propargylpyridinium salt of the general formula

Die Erfindung bezieht sich auf ein galvanisches Nickelbad. Wenn man auf galvanischem Wege Nickelüberzüge herstellen will, dann muß man den Bädern sogenanntes Glanzmittel zusetzen. Man unterscheidet primäre Glanzmittel, die in sehr geringen Konzentrationen von beispielsweise 0,002 bis 0,2 g/l verwendet werden, und sekundäre Glanzmittel, welches beispielsweise in einer Konzentration von 1 bis 30 g/l verwendet werden. Die richtige Kombination dieser Materialien ergibt spiegelglänzende überzüge, wobei unter Umständen auch ein Einebnungseffekt zu verzeichnen ist. ' ' iThe invention relates to a galvanic nickel bath. If you have nickel plating by electroplating want to produce, then you have to add so-called brighteners to the baths. One distinguishes primary brighteners used in very low concentrations of, for example, 0.002 to 0.2 g / l and secondary brighteners, which can be used, for example, in a concentration of 1 to 30 g / l be used. The right combination of these materials results in mirror-like coatings, whereby under certain circumstances a leveling effect can also be recorded. '' i
Es sind bereits Verschiedene Glanznickelsysteme, die aus einer Kombination aus einem primären Glanzmittel und einem sekundären Glanzmittel bestehen, bekannt.There are already various bright nickel systems that consist of a combination of a primary brightening agent and a secondary brightener are known.
So ist in der deutschen Auslegeschrift 1 066 068 ein Glanznickelbad beschrieben, welches neben einem sekundären Glanzmittel, üblicherweise aromatische Sulfonsäuren, als primäres Glanzmittel ein Pyridiniumsalz enthält, das am Stickstoffatom durch eine Kette mit einer dreifachen Umsättigung substituiert ist und am Kern bis zu drei Halogenatome oder Sulfonsäuregruppen enthalten kann. Ein Beispiel für ein solches primäres Glanzmittel ist N-2-Propinpyridin-bromid. Ein Nachteil der mit solchen Bädern hergestellten Nickelüberzüge besteht darin, daß die Nickelüberzüge einen stark irisierenden Schleier innerhalb eines großen Stromdichtebereichs, der üblicherweise für die galvanische Abscheidung verwendet wird, zeigt.Thus, in the German Auslegeschrift 1 066 068, a bright nickel bath is described, which in addition to a secondary brighteners, usually aromatic sulfonic acids, as the primary brightener a pyridinium salt contains, which is substituted on the nitrogen atom by a chain with a triple unsaturation and can contain up to three halogen atoms or sulfonic acid groups on the core. An example one such primary brightener is N-2-propyne pyridine bromide. A disadvantage of the nickel coatings produced with such baths is that the Nickel coatings create a highly iridescent haze within a wide range of current densities that are commonly found used for electrodeposition shows.

Die erfindungsgemäßen Nickelbäder ergeben brillante Nickelabscheidungen mit einer vorzüglichen Duktilität und einer guten Glanzentwicklung im Bereich niedriger Stromdichte. Außerdem ist die Einebnungsgeschwindigkeit sehr hoch. Ein wesentlicher Vorteil der erfindungsgemäßen Bäder ist, daß die Glanzmittel innerhalb verhältnismäßig großer Konzentrationen enthalten sein können, so daß eine genaue Kontrolle der Konzentrationen der Glanzmittel im Bad nicht nötig ist.The nickel baths according to the invention produce brilliant nickel deposits with an excellent one Ductility and good gloss development in the area of low current density. In addition, the leveling speed is very high. A major advantage of the baths according to the invention is that the brighteners can be used within relatively large concentrations may be included, so that a precise control of the concentrations of the brighteners in the Bath is not necessary.
Ein anderer Vorteil liegt darin, daß die im erfindungsgemäßen Bad enthaltenen Glanzmittel auch bei langer Elektrolyse keine schädlichen Zersetzungsprodukte bilden. Another advantage is that the brighteners contained in the bath according to the invention are also included do not form harmful decomposition products for long periods of electrolysis.
Die primären Glanzmittel sind in einer Konzentration von 0,005 bis 0,10 g/l enthalten. Die jweils gewählte Konzentration hängt von der Badtype und auch von anderen Faktoren, wie z. B. Konzentration der Nickelsalze, den Arbeitsbedingungen, dem gewünschten Glanzgrad und dem gewünschten Einebnungsgrad ab. Konzentrationen zwischen 0,01 und 0,05 g/l werden bevorzugt verwendet.The primary brighteners are contained in a concentration of 0.005 to 0.10 g / l. The each The concentration chosen depends on the type of bath and other factors, such as B. Concentration the nickel salts, the working conditions, the desired degree of gloss and the desired level of flattening away. Concentrations between 0.01 and 0.05 g / l are preferred.
Typische Verbindungen, welche als primäre Glanzmittel wirksam sind, sind die folgenden:Typical compounds that are effective as primary brighteners are the following:
