Description

Acid Red 194 is a synthetic, water-soluble azo dye belonging to the acid dye class, valued for its bright red hue and good fastness properties. It is a critical component for imparting vibrant and durable color to protein-based fibers like wool, silk, and nylon, as well as leather and paper. This dye is essential for manufacturers in the textile, leather finishing, and specialty paper industries seeking consistent, high-quality coloration. The compound is identified by CAS No. 11075-30-2.

Application

• Primary dyeing and printing of wool and silk textiles.
• Coloration of nylon fibers and fabrics.
• Leather finishing for dyeing leather goods such as upholstery, apparel, and accessories.
• Manufacture of colored paper and specialty paper products.
• Ink formulation for specific writing inks and jet printing inks.
• Staining and coloring for biological samples and laboratory applications.
• Production of cosmetics like hair dyes and temporary colorants (subject to regulatory approval).
• As a colorant for food packaging materials (where indirect food contact compliance is required).
