ABSTRACT:
This invention relates to a method of producing lustrous to brilliant zinc electrodeposits, which comprises passing current from a zinc anode to a metal cathode for a time period sufficient to deposit a lustrous to brilliant zinc electrodeposit upon said cathode; the current passing through an aqueous acidic bath composition containing at least one zinc compound providing zinc cations for electroplating zinc, and containing as cooperating additives at least one bath soluble substituted or unsubstituted polyether, at least one aliphatic unsaturated acid containing an aromatic or heteroaromatic group and at least one aromatic nitrogen heterocyclic compound.
