Abstract
Abstract In accordance with certain of its aspects this invention relates to a process of producing bright zinc electrodeposits which comprises passing current from an anode to a metal cathode through an aqueous bath composition containing at least one zinc compound providing zinc ions for electroplating zinc, a bathsoluble polyether, and at least one non-aromatic Alpha , Beta unsaturated carbonyl compound for a time period sufficient to deposit a bright zinc electrodeposit upon said cathode.

The method as claimed in claim 1 wherein the non-aromatic Alpha , Beta -unsaturated carbonyl compound has a formula selected from the group consisting of:
Claim 3
Dependent Claim
32 words
The method as claimed in claim 1 wherein the Alpha , Beta -unsaturated carbonyl compound has the formula: wherein each R'' is independently hydrogen or an organic radical of one-10 carbon atoms.
Claim 4
Dependent Claim
33 words
The method as claimed in claim 1 wherein at least one Alpha , Beta -unsaturated carbonyl compound is selected from the group consisting of citral, 6-methyl-5,6-dihydrobenzaldehyde, carvOne, piperitone, isojasmone, 4-(3-cyclohexene)-3-butene-2-one, and mesityl oxide.
