Abstract
An improved process and composition for the preparation of nickel or nickel alloy electrodeposits is provided. The process involves passing current from a anode to a cathode through an aqueous acidic electroplating solution containing zinc ions as impurities with the combination of at least one nickel compound, saccharin, and a sulfonated acetylenic compound or salt thereof, particularly propyne sulfonic acid. The invention is particularly useful for electroplating nickel onto a zinc die cast substrate, where zinc ion impurity build-up in the bath occurs.
