Description

Acid Green 85 is a synthetic, water-soluble acid dye belonging to the anthraquinone chemical class. This high-purity dye is valued for its bright green hue and excellent fastness properties, making it a critical component for achieving consistent and durable coloration. It is primarily used in the textile industry for dyeing protein fibers like wool, silk, and nylon, as well as in the production of inks, leather, and paper. Our supply of Acid Green 85 CAS NO 12220-00-7 is backed by stringent quality control to ensure batch-to-batch consistency for industrial applications.

Application

• Textile Dyeing: Primary application for dyeing wool, silk, nylon, and other polyamide fibers to achieve vibrant green shades with good wash and light fastness.
• Leather Coloring: Used in the dyeing of leather goods, providing rich, penetrating color for footwear, apparel, and upholstery.
• Ink Manufacturing: Serves as a colorant for specialty inks, including those used in packaging, security printing, and writing instruments.
• Paper Staining: Employed in the production of colored papers, decorative tissues, and security papers requiring specific color identification.
• Biological Staining: Potential use as a histological stain in laboratory settings for microscopic analysis, though specific grade suitability must be confirmed.
• Specialty Coatings: Can be incorporated into coatings and paints where a specific acid dye colorant is required.
