Description

C.I. Basic Red 15 is a synthetic cationic dye belonging to the azo chemical class, valued for its vibrant red hue and strong affinity for polyacrylonitrile fibers. This compound is a critical component for achieving consistent, high-quality coloration in industrial dyeing and printing processes. It is primarily utilized by manufacturers in the textile, paper, and specialty ink industries seeking reliable and efficient colorants.

Application

• Textile Dyeing: Primary application for dyeing acrylic, modacrylic, and other cationic-dyeable synthetic fibers.
• Paper Coloring: Used in the production of colored papers, tissues, and paperboard where a bright red shade is required.
• Ink Manufacturing: A key pigment for specialty inks, including those for security printing and flexographic applications.
• Leather Finishing: Employed in the dyeing of leather goods to provide rich, durable red colors.
• Biological Staining: Can be used as a histological stain in laboratory settings for microscopic analysis.
• Plastics and Polymers: Suitable for mass coloration of certain plastics where color fastness is important.
