Description

Cisolventblue104 is a high-purity solvent dye belonging to the anthraquinone chemical class, identified by CAS No. 71872-84-9. This compound is valued for its excellent solubility in a wide range of organic solvents and its ability to impart a strong, stable blue coloration. It is a critical material for manufacturers in the plastics, ink, and specialty coatings industries who require consistent, high-performance colorants for their formulations.

Application

• Primary colorant for solvent-based inks, including flexographic and gravure printing inks.
• Dyeing agent for engineering plastics such as polystyrene (PS), polycarbonate (PC), and polymethyl methacrylate (PMMA).
• Coloration of lacquers, wood stains, and industrial coatings where solvent compatibility is paramount.
• Manufacturing of colored synthetic fibers during the polymer melt-spinning process.
• Staining and marking of fuels and lubricants for identification purposes.
• Production of specialty color filters and optical media.
• Used in ballpoint pen inks and other writing instruments.
• Research and development applications as a tracer or indicator dye in analytical chemistry.
