PROBLEM TO BE SOLVED: To deposit a mat metallic layer free of nickel and chromium. SOLUTION: For coating a substrate with a first mat metallic layer, and obtaining a coated-substrate having a matting-treated surface, the first mat metallic layer is metallized with a second metallic layer which partakes of the mat effect of the first metallic layer. The first mat metallic layer does not comprise nickel, and the second metallic layer does not comprise nickel and chromium (VI). Metal for producing the first mat metallic layer is at least one metal among copper, silver, tin, zinc and alloys comprising no nickel, and metal for producing the second metallic layer is at least one metal among copper, tin, zinc, chromium (III), silver, gold, ruthenium, platinum, palladium and their alloys.
