Description

Acid Blue 183 is a synthetic, water-soluble acid dye belonging to the anthraquinone chemical class, valued for its bright and stable blue hue. It is a critical component for achieving high-quality, durable coloration on protein-based fibers like wool, silk, and nylon. This dye is essential for manufacturers in the textile, leather finishing, and specialty paper industries seeking consistent, vibrant color results with good fastness properties. The compound is identified by CAS No. 12217-22-0.

Application

Acid Blue 183 is primarily utilized for dyeing and printing applications where color fastness and brilliance are paramount. Its specific uses include:

• Textile Dyeing: Exhaust and continuous dyeing of wool, silk, and polyamide (nylon) fibers and fabrics.
• Leather Coloration: Providing vibrant and uniform blue shades on finished leather goods.
• Paper Staining: Used in the production of specialty and decorative papers.
• Ink Formulation: A colorant component in certain types of inks for non-impact printing.
• Biological Staining: Potential use as a histological stain in laboratory settings.
