Method for producing matt copper deposits |
| abstract |
The present invention relates to a method for deposition of a matte copper coating wherein a first copper layer is deposited from an aqueous copper electrolyte which does not contain an organic compound comprising divalent sulfur. A second copper layer is then deposited onto the first copper layer from an aqueous copper electrolyte comprising a first and a second water soluble sulfur-containing additive wherein the first water soluble sulfur-containing compound is an alkyl sulfonic acid derivative and the second water soluble sulfur-containing additive is an aromatic sulfonic acid derivative. The method provides copper layers with a homogeneous and adjustable matte appearance for decorative applications. |
