Reactive dye:Vinyl Sulfone dyes, also known as Remazol® dyes-
The trademarked name under which they were first introduced, are a type of fiber reactive dye that is often used in silk painting. Although silk paintings made with vinyl sulfone dyes are usually steamed to set the dye, the dyes can also be "batch cured" at warm room temperatures.
In a reactive dye a chromophore contains a substituent that reacts with the substrate. Reactive dyes have good fastness properties owing to the bonding that occurs during dyeing. Reactive dyes are most commonly used in dyeing of cellulose like cotton or flax, but also wool is dyeable with reactive dyes. Reactive dyeing is the most important method for the coloration of cellulosic fibres. Reactive dyes can also be applied on wool and nylon; in the latter case they are applied under weakly acidic conditions. Reactive dyes have a low utilization degree compared to other types of dyestuff, since the functional group also bonds to water, creating hydrolysis.
