Vat Blue 4 & Vat Blue 6
Vat Blue 4 and Vat Blue 6 are anthraquinone-based vat dyes used in textile colouration. Although they belong to the same broad dye family, they have different chemical identities and colour characteristics.
Vat Blue 4
Vat Blue 4 is an important blue vat dye identified by CAS Number 81-77-6 and C.I. 69800. It is also known as Indanthrone and is recognised for its deep blue shade. The dye is practically insoluble in water and is applied through a reduction process that converts it into a soluble leuco form. After absorption by the fibre, oxidation restores the insoluble dye form, helping develop the final colour.
Vat Blue 6
Vat Blue 6, also known as Dichloroindanthrone or Indanthrene Blue BCF, is identified by CAS Number 130-20-1 and C.I. 69825. It is a chlorinated anthraquinone vat dye generally associated with an aquamarine to bluish-green shade. Like other vat dyes, it is practically insoluble in water and requires a suitable reduction and oxidation process during application. It is used in textile dyeing where its characteristic shade is required.
