Description

Catonic Yellow X-8Gl is a synthetic cationic dye belonging to the methine or polymethine class, identified by CAS No. 12217-50-4. This product is engineered to provide intense, vibrant coloration with excellent substantivity to negatively charged substrates, making it a critical component for quality assurance and product differentiation. It is primarily required by manufacturers in the textile, paper, leather, and specialty ink industries seeking reliable, batch-to-batch consistent dyes for their processes.

Application

• Textile Dyeing and Printing: For coloring acrylic, modacrylic, and cationic-dyeable polyester fibers, as well as silk and wool, offering good lightfastness and wash fastness.
• Paper Coloration: Used in the production of specialty papers, including tinted papers and security papers, where strong dye fixation is required.
• Leather Finishing: Imparts bright, uniform color to leather goods in the finishing stages of production.
• Ink Manufacturing: Serves as a colorant in the formulation of inks for ballpoint pens, ink-jet inks, and other specialty writing fluids.
• Biological Staining: Potential use as a cationic stain in histology and microbiology for highlighting cellular structures.
• Plastics and Polymers: For mass coloration of certain plastics where compatibility with the polymer matrix is achieved.
