Description

C.I.Mordant Green 22 is a synthetic organic dye belonging to the mordant dye class, identified by CAS NO 10290-07-0. Its primary value lies in its ability to form stable, colorfast complexes with metal ions, particularly chromium, resulting in deep, durable green shades. This product is essential for industrial applications requiring high wash and light fastness, primarily serving the textile dyeing and leather finishing sectors where robust coloration is critical.

Application

• Textile Dyeing: Used for dyeing wool, silk, and nylon fibers, producing greens with excellent fastness properties when pre-mordanted with metal salts.
• Leather Finishing: Applied in the coloring of leather goods, providing rich, stable green hues that resist fading.
• Wood Staining: Employed in specialized wood stain formulations to achieve consistent and durable green tones.
• Paper Coloring: Utilized for tinting specialty papers where color stability is required.
• Biological Staining: May serve as a histological stain in laboratory settings for microscopic analysis.
• Ink Manufacturing: A component in the production of certain industrial and specialty printing inks.
