Remazol or vinyl sulfone
by : --
dyes are usually used for silk painting and fixed by steaming, but, like Procion H dyes, may be fixed to cotton using a high-pH solution such as sodium silicate at room temperature, or by moderate heating. Vinyl sulfone dyes are particularly useful for chemical resist dyeing (PDF), in which two different types of fiber reactive dyes are used to print foreground and background in different colors. Remazol dyes are more suitable for dyeing for later discharge (bleaching) than are other fiber reactive dyes. For a large amount of additional information, see Vinyl Sulfone Fiber Reactive Dyes.
