Bright Orange / C.I. 16
Reactive Orange 3R (Remazol Orange 3R) is a brilliant, reddish-orange monoazo dye. It acts as a versatile workhorse in textile dyeing, widely used for dyeing cotton, viscose, and rayon. It is highly valued for its good solubility and excellent dischargeability, making it the top choice for creating patterned fabrics.
Reactive Orange 3R is a Vinyl Sulfone dye applied at 60°C. It forms a stable chemical bond with the fiber. It is a key component in "Trichromy" (color mixing), often combined with Reactive Black B and Red to create cost-effective brown, olive, and earth tones.
High concentration grade for maximum depth.
