ABSTRACT:
Improved electrolytic tin deposition from aqueous, acid electroplating baths is achieved by addition of a new formula of brighteners. These results are achieved by further addition of unsaturated aliphatic acids or their derivates and still better results are achieved by further addition of certain heterocyclic quarternary compounds.
