Description

Acid Green 104 is a synthetic acid dye belonging to the anthraquinone chemical class, valued for its bright green hue and good lightfastness. This dye is engineered to deliver consistent, vibrant coloration with strong affinity for protein-based fibers like wool, silk, and nylon. It is a critical component for manufacturers in the textile, leather, and specialty paper industries seeking reliable and high-performance green dyes for their products.

Application

• Textile Dyeing: Primary application for dyeing wool, silk, and nylon fibers to achieve a bright green shade.
• Leather Finishing: Used in the coloration of leather goods, providing rich and durable green tones.
• Paper Staining: Employed in the production of specialty and decorative papers requiring colorfast green pigments.
• Ink Formulation: A component in the manufacture of certain inks, particularly for non-impact printing or specialty applications.
• Biological Staining: Potential use as a histological stain in laboratory settings for microscopic analysis.
• Plastics and Polymers: Can be used for coloring certain types of plastics and synthetic materials.
