Abstract
It has been found that aminated polyepichlorohydrins prepared by reacting polyepichlorohydrin with an amine selected from the group consisting of secondary aliphatic amines and secondary alicyclic amines result in a zinc electroplating bath brightener. Additionally, an aqueous, acid electroplating bath containing the aminated polyepichlorohydrin as well as polyoxyethylene condensates, and aromatic aldehydes and ketones act synergistically to provide bright, lustrous electrodeposits of zinc.
