Description

C.I. Basic Blue 63 is a synthetic cationic dye belonging to the triarylmethane class, widely recognized for its intense blue coloration. It is a critical component in the production of high-quality, colorfast inks and toners, particularly for specialized printing applications. This product is essential for manufacturers in the ink, plastics, and specialty paper industries seeking reliable and consistent blue pigments.

Application

• Inkjet Inks & Toners: A primary colorant for producing cyan components in high-performance digital printing inks and laser printer/toner cartridges.
• Plastics Coloring: Used for mass coloration of various polymers, including ABS, polystyrene, and polycarbonate, where good dispersion and thermal stability are required.
• Specialty Paper & Cardboard: Employed in the dyeing of specialty papers, security papers, and decorative cardboard for packaging.
• Textile Auxiliary: Functions as a shading agent or component in dye mixtures for synthetic fibers, though its lightfastness on textiles is limited.
• Biological Staining: Used in specific histological and microbiological staining procedures as a contrast dye.
• Lacquers & Coatings: Incorporated into solvent-based lacquers and coatings for wood, metal, or plastic to provide a transparent blue hue.
