Abstract

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°C and subsequent buffering at a temperature of 40-110°C with an oxidizing solution based on sodium thiosulfate, a reagent metal and an acidifying compound.
