Abstract
A composition and method for electrodepositing ductile, bright, well leveled copper deposits from an aqueous acidic copper plating bath having dissolved therein from about 0.04 to about 1000 milligrams per liter of a poly (alkanol quaternary ammonium salt) formed as the reaction product of a polyalkanolamine with an alkylating or quaternization agent. The polyalkanolamine constituent typically is formed as the reaction product of a polyalkylenimine (e.g. polyethylenimine) with an alkylene oxide.
