A novel composition is described which is an aqueous oxidizing solution containing: (a) about 0.01 to about 10% by weight of an oxidant selected from the water-soluble iodate salts and the water-soluble bromate salts; (b) about 0.005% to about 5% by weight of a water-soluble vanadate salt; and (c) about 0.05 to about 10% of a water-soluble nitrate salt. An improved process for oxidizing vat or sulfur dyes is also described wherein the reduced form of the dye is oxidized by contact with the novel composition.
