New Synthetic Approaches for Pyrazole Fused Systems as Reactive Dyes

Reactive dyes are one of the most “fast” dyes when applied to a cellulosic substrate due to its covalent bonding. Although reactive dyes can be used on different non-textile applications these are a typical textile dyer’s choice for cotton wool silk and nylon due to the excellent fastness properties and bright shade range. Many textile dyeing application methods can be used such as exhaust continuous package jet dyeing garment dyeing and printing.
