Reactive Blue 19 is one of the most famous and widely used reactive dyes, celebrated for its exceptionally brilliant, pure royal blue shade. As a vinyl sulfone (VS) dye based on an anthraquinone chromophore, it offers a unique combination of shade brightness and high fixation. It is a versatile workhorse for dyeing all types of cellulosic fibres, providing a level of vibrancy that is a benchmark in the industry.
