Mediator systems obtainable by mixing a salt of an electrochemically active complexing metal (M1) capable of forming a plurality of valence states with a hydroxyl-containing complexing agent, which may likewise be present as salt, and with a salt of an electrochemically inactive complexing metal (M2) in an alkaline aqueous medium, wherefor the molar ratio of metal ion M2 to metal ion M1 is from 0.8:1 to 2:1 are useful for reducing dyes and dyeing cellulosic textile material.

Mediator systems based on mixed metal complexes, used for reducing dyes

From 5 to 60% by weight aqueous alkaline solutions of reduced indigoid dyes are prepared by reducing the indigoid dye electrochemically in the presence of a mediator.
