anthraquinone dye (synthetic dye, <dye by composition or origin>, ... Materials (hierarchy name)) |
|
Note: An important class of synthetic vat dyes whose structure is based on anthraquinone. The resonance structure from the aromatic rings and the carbonyl groups provide the chromophore. Anthraquinone dyes were first sold commercially in 1901. They are vat dyes that must first be reduced with caustic soda and sodium hydrosulfite to produce a soluble compound, then once impregnated in the fiber and dried, they are oxidized with sodium perborate to form the original colorant. Anthraquinone dyes are lightfast and wash fast. Examples of anthraquinone dyes include anthrapyrimidine yellow (Pigment Yellow 108), anthraquinoid red (Pigment Red 177), and indanthrone blue (Pigment Blue 60).
