- Halogen-Cyano Disperse Azo Dyes for Hydrophobic Fiber Fastness
Halogen- and cyano-substituted disperse azo dyes improve light and washing fastness while maintaining level dyeing on polyester and other hydrophobic fibers.
- Water-Soluble Azo Dye Composition for Lightfast Brown Papers
Single water-soluble azo dyes with multiple azo groups give brown papers stronger lightfastness without relying on complex dye mixtures.
- Cyano-Halogen Azo Dye Composition for Fast Polyester Dyeing
Cyano-halogen phthalimide azo dyes improve light and washing fastness on polyester while maintaining level dyeing and simpler synthesis.
