Description

Acid Red 226 is a synthetic monoazo acid dye renowned for its bright, vivid red color and excellent tinctorial strength. This high-performance dye is engineered for superior fastness properties, including lightfastness and washfastness, making it a critical component for achieving durable coloration. It is primarily utilized by manufacturers in the textile, leather, and paper industries seeking reliable and vibrant red shades for their products.

Application

• Textile Dyeing: Primary application for dyeing nylon, silk, wool, and modified acrylic fibers to achieve brilliant red hues.
• Leather Finishing: Used for coloring leather goods, providing rich, uniform color with good penetration and adhesion.
• Paper Coloring: Employed in the production of specialty papers, decorative papers, and packaging materials.
• Ink Formulation: A key pigment for manufacturing inks used in ballpoint pens, stamp pads, and other writing instruments.
• Biological Staining: Potential use as a histological stain in laboratory settings for microscopic analysis.
• Plastics and Polymers: Can be used for coloring certain types of plastics where acid dye compatibility exists.
