Process for providing a tortoise-shell chromatic effect to metallic substrates |
| 摘要 |
<p>The present invention relates to a chemical process for providing a tortoise-shell chromatic effect to nickelated metallic substrates, which comprises heating the metallic substrate to 100-110 DEG C and subsequent buffering at a temperature of 40-110 DEG C with an oxidizing solution based on sodium thiosulfate, a reagent metal and an acidifying compound.</p> |
