The reduction of vat dyes by an indirect electrolytic process is described. The dyeing procedure and the relevant dyeing parameters for this new reduction technique are discussed. The dyeing results are comparable with those obtained by standard experiments using sodium dithionite. After removal by filtration techniques of the remaining dye from the exhausted dyebath, regeneration of the reducing agent by cathodic reduction is possible. The results demonstrate the applicability of this reduction method for larger‐scale vat dyeing procedures.
