Reactive Blue 220 is a high-performance, bifunctional reactive dye that produces an exceptionally bright, neutral blue shade. As a metal-complex dye, it offers very good lightfastness. It is a key component in some trichromatic dyeing systems, valued for its high fixation rate, excellent build-up, and good compatibility with other trichromatic dyes. Its outstanding brightness makes it a benchmark blue for achieving a vast spectrum of vibrant, reproducible shades.
