Reactive Blue 71 is a “hot brand” reactive dye based on a phthalocyanine chromophore. It is designed for high-temperature dyeing applications where it achieves excellent fixation and durability. It produces a brilliant, clean turquoise shade, characteristic of phthalocyanine colourants. This dye is a reliable choice for achieving vibrant and long-lasting turquoise colours on cellulosic fibres with good overall fastness properties, particularly in high-temperature exhaust dyeing.
