Bismark is a synthetic water-soluble dye known for its intense dark blue to black coloration, widely used in textile dyeing, printing, and laboratory applications. It provides excellent colorfastness, brightness, and uniform dispersion in aqueous systems. This dye is favored for its stability across a broad pH range and its strong affinity for protein and synthetic fibers, making it valuable in industrial, cosmetic, pharmaceutical, and research settings.
