Abstract (en)
[origin: WO2022123012A1] The present invention relates to a very specific electroplating bath for depositing a black chromium layer, and a respective method for electroplating such a layer. The electroplating bath comprises two specific groups of compounds defined as (D) and (E), present in a particularly defined molar ratio ranging from 0.9 to 2.65, based on (E) : (D). The black chromium layer is excellently suited for decorative purposes.
