C.I. Reactive Blue 69 is a blue reactive dye with bright shade, good solubility and high cost-effectiveness. It is especially suitable for medium to light color cellulosic fiber products that require bright blue and green tones. It has outstanding value in printing and color matching fields, but it is not suitable as the main dye for high-fastness dark color products.
