Description

Basic Red 22 is a synthetic cationic dye belonging to the azo class, widely recognized for its vibrant red color and strong affinity for polyacrylonitrile fibers. Its primary value lies in providing excellent color fastness, brightness, and leveling properties in demanding industrial dyeing processes. This product is essential for manufacturers in the textile, paper, and leather industries seeking reliable and consistent coloration. The compound, identified by CAS No. 12221-52-2, is a key component for creating a range of red to violet shades on various substrates.

Application

• Textile Dyeing: Primary application for dyeing acrylic fibers, modacrylic, and certain polyamide fibers, offering excellent wash and light fastness.
• Paper Coloring: Used in the surface coloring and tinting of specialty papers, including decorative and security papers.
• Leather Finishing: Imparts color to leather goods, providing uniform dyeing for products like upholstery, bags, and accessories.
• Ink Manufacturing: Serves as a colorant for the formulation of inks used in stamp pads, flexographic, and other specialty printing applications.
• Biological Staining: Potential use as a histological stain in laboratory settings for microscopic analysis.
• Plastics and Polymers: Can be incorporated for the mass coloration of certain plastics where compatibility is confirmed.
