Description
A class of water-insoluble dyes. A brown sulfur dye, called cachou de Laval, was first prepared in France in 1873 by heating sawdust with sulfur and caustic soda. A second sulfur dye, vidal black was made in 1893. To prepare a sulfur, or sulfide, dye, an insoluble dye is reduced with sulfur or sodium sulfide to make a colorless, water-soluble compound. The dye is then applied, usually to cotton. Once dried, the dye is oxidized back to its colored, water-insoluble state. In general, sulfur dyes are dark colors with moderate lightfastness, good washfastness and poor bleach fastness. Example of sulfur dyes are indophenol and sulfur black (CI 5318).
