Vat dyes

These dyes are essentially water-insoluble and contain at least two carbonyl groups (C=O) that enable the dyes to be converted by means of reduction under alkaline conditions into a corresponding water-soluble ‘leuco compound’. It is in this form that the dye is absorbed by the cellulose; following subsequent oxidation the leuco compound regenerates the parent form, the insoluble vat dye, within the fiber.

The most important natural vat dye is Indigo or Indigotin found as its glucoside, Indican, in various species of the indigo plant indigofera. Vat dyes are used where very high light- and wet-fastness properties are required.

Derivatives of indigo, mostly halogenated (especially bromo substituents) provide other vat dye classes including: indigoid and thioindigoid, anthraquinone (indanthrone, flavanthrone, pyranthone, acylaminoanthraquinone, anthrimide, dibenzathrone and carbazole).
