Monoazo Dyes TRIZ Cases
- Monoazo Dye Compounds for Improved Fastness and Low Wastewater Coloration
Monoazo compounds with specific substituents improve light and wet fastness while minimizing colored wastewater discharge during textile and paper dyeing.
- Magenta Ink Jet Composition Using Anthrapyridone and Azo Dyes
Combining anthrapyridone and azo dyes in specific ratios improves lightfastness and gas resistance for stable image storage.
- Ink Set Hue Angle Control for Ozone Resistance
An ink set limits hue angle changes in yellow, magenta, and cyan dyes to preserve image stability.
