Thanks and best regards
Vat dyes are not as difficult to find as Naphthol dyes (yesterday’s question). A good retail source for vat dyes in Europe is Granat Farvekompagniet in Denmark. Look for their page of Granat Kypefarver/Batikfarver.
Vat dyes are widely available in many countries, including countries in Africa in which other classes of dye can be difficult to find. North American dyesellers from which vat dyes can be ordered include Aljo Manufacturing, PRO Chemical & Dye, and Maiwa Handprints. In Australia, Batik Oetoro sells Indanthren Vat dyes. (More information for each of these companies is available on my page, Sources for Dyeing Supplies Around the World.)
Vat dyes are not as suitable for beginners as Fiber Reactive dyes, but they are neither difficult nor dangerous to use, assuming normal safety precautions with safety goggles and gloves. The dyes are usually purchased in an insoluble oxidized form, and must be chemically reduced in order to solubilize them and get them inside the textile fiber; when the fiber is then exposed to air again, the dyes re-oxidize and become insoluble, so that the dye inside the fiber becomes fixed in place.
Vat dyes are particularly interesting for printing on fabric that has been dyed with dischargeable dyes, such as Remazol dyes or most Procion dyes. The same chemicals that are used to solubilize and reduce the vat dye will remove the existing color from the dye on the fabric, allowing the brightness of the vat dye in your design to contrast sharply with the background color. Granat Kypefarver/Batikfarver’s range of Vat dyes has been especially selected for being suitable for illumination dyeing on backgrounds made with Fiber Reactive dye.
Another useful property of Vat dyes is that most of them are less susceptible to fading than other types of dye. Not all Vat dyes are equally light resistant, but many are significantly more light-resistant than Fiber Reactive dyes or Direct dyes.
A specialized category of Vat dyes is light-sensitive pre-reduced Vat dye, which can be used to make single-color photographic prints on fabric. There are two brands of this amazing product available, with slightly different colors. Jacquard Products makes SolarFast light sensitive dyes, in fourteen different colors, and Lumi makes Inkodye, available in nine colors. Unlike sun-printed fabric paints such as Setacolor, the light-sensitive dye does not change the feel of the fabric, and it wears better than fabric paint since the dye penetrates the fiber. Since it is actually visible light that fixes the dye, rather than the heat from the infrared in sunlight as for fabric paints, inkjet transparencies with photographs or drawings can be used to make quite detailed designs.
