Electrolytic Copper foil and process for producing the same

摘要

In a process for the production of an electrolytic copper foil from a sulfurically acidic copper sulfate electrolytic solution, the sulfurically acidic copper sulfate electrolytic solution contains additives of 0.1 to 1.0 g/l of an oxyethylenic surfactant, 50 to 250 mg/l of a chloride, 1 to 10 mg/l of a glue or gelatin and 1 to 10 mg/l of a nitrogen-containing organic compound.
