Acid Blue 15 is a general-purpose leveling acid dye from the triarylmethane class. It produces a neutral to slightly reddish-blue shade and is known for its good solubility and reliable dyeing performance on protein and polyamide fibers. Its primary advantage is its excellent leveling characteristic, which ensures a consistent and uniform color, even on materials with variable dye affinity. This makes it a cost-effective and dependable choice for piece and yarn dyeing.
