ABSTRACT:
The instant invention is directed to an aqueous bath for the electrodeposition of a bright iron-nickel alloy and to a process utilizing the same, the bath comprising iron ions, nickel ions, an iron complexing agent containing at least two complexing groups independently selected from the group consisting of carboxy and hydroxy provided at least one group is a carboxy group, and a reaction product of a polyamine and an alkylating or sulfonating agent, whereby there is achieved a marked improvement in the brightness of the electrodeposit as well as excellent leveling in both the high and low current density areas. Optionally, by the addition of acetylenic brighteners of a particular structural formula even further improved results may be obtained.
