ABSTRACT:
The present invention is directed to an aqueous bath for the electrodeposition of bright metal deposits, and is more particularly concerned with a bath composition which provides upon the basis metal an electrodeposit having improved brightness, superior adhesion to the substrate, and as well, a condition of ductility markedly better than that obtained from certain prior art baths. The electroplating bath composition of this invention includes therein a sulfamalkylated polyamine which is a reaction product containing nitrogen substituted alkyl sulfamate units represented by the general formulae: ##STR1## WHERE M = H, Li, Na, K or NH.sub.4,
