Description

Disodium 2-[[6-[[6-Anilino-4-[4-Sulphamoylphenyl]-1,3,5-Triazin-2-Yl]Amino]-2-Naphthyl]Azo]-5-[(4-Sulphonatophenyl)Azo]Benzenesulphonate is a high-purity, water-soluble anionic dye belonging to the class of reactive or direct dyes, known for its strong color strength and excellent substantivity. This compound is engineered to deliver superior fastness properties, including light and wash fastness, making it a critical component for demanding coloration processes. It is primarily required by manufacturers in the textile, leather, and specialty paper industries seeking reliable and vibrant colorants for natural and synthetic fibers.

Application

• Textile Dyeing: Primary application for dyeing cotton, wool, silk, and nylon fabrics, offering excellent exhaustion and fixation.
• Leather Finishing: Used for coloring leather goods, providing uniform and deep shades with good rub fastness.
• Paper Coloring: Employed in the production of high-quality colored papers, including decorative and security papers.
• Ink Formulation: Serves as a colorant for specialty inks, including those for ink-jet printing and packaging.
• Biological Staining: Potential use as a histological stain in laboratory settings due to its specific affinity.
• Research & Development: Utilized as a standard or intermediate in chemical research for developing new dye molecules and studying chromophore properties.
