Description

C.I. Acid Violet 80 is a synthetic anthraquinone-based acid dye, valued for its bright and stable violet hue. It is engineered to deliver excellent color fastness and leveling properties on protein fibers like wool, silk, and nylon. This dye is essential for manufacturers in the textile, leather, and paper industries seeking high-performance, reliable coloration for their products.

Application

• Textile Dyeing: Primary application for dyeing wool, silk, and polyamide (nylon) fibers, providing vibrant violet shades with good wash and light fastness.
• Leather Finishing: Used for coloring leather goods, offering rich, uniform color penetration and durability.
• Paper Staining: Employed in the production of specialty papers, decorative tissues, and security papers requiring color consistency.
• Ink Formulation: A colorant component in certain types of inks for non-impact printing and specialty marking.
• Biological Staining: Potential use as a histological stain in laboratory settings for microscopic analysis.
• Industrial Colorant: Suitable for coloring other substrates where an acid dye mechanism is applicable.
