Reactive Blue 25 is a dichlorotriazine (DCT) reactive dye from the anthraquinone class, making it a “hot brand” dye. It is designed for optimal performance when dyeing cellulosic fibres at high temperatures (approx. 80°C). It produces a clean, greenish-blue shade and is valued for its robust performance and good fastness properties after fixation. It is a reliable choice for exhaust dyeing processes where a specific green-blue tone is needed.
