Description
Chromium, 2,4-dihydro-4-[(2-hydroxy- 5-nitrophenyl)azo]-5-methyl-2-phenyl-3H-pyrazol-3 -one 4-hydroxy-3-[(2-hydroxy-1- naphthalenyl)azo]benzenesulfonamide N-[7-hydroxy-8-[(2-hydroxy- 5-nitrophenyl)azo]-1-naphthalenyl]acetamide sodium complexes is a high-performance, complex chromium-based azo dye. This compound is engineered for exceptional color strength, lightfastness, and stability in demanding industrial applications. It is primarily sought after by manufacturers in the textile, leather, and specialty coatings industries requiring durable and vibrant coloration.
Application
- Textile Dyeing: For dyeing natural and synthetic fibers, particularly where high wash and light fastness are critical.
- Leather Finishing: Used in the coloration of leather goods, providing rich, penetrating shades with good rub resistance.
- Industrial Coatings & Paints: Imparts color to coatings for plastics,纸张 (paper), and other substrates requiring organic pigment performance.
- Ink Formulation: A key component in the production of printing inks for packaging and publications.
- Specialty Plastics: For the mass coloration of polymers where heat stability during processing is required.
- Paper Coloration: Used in the surface coating or beater dyeing of paper and board.
