Description

Acid Blue 119 is a synthetic anthraquinone-based acid dye known for its bright, clear blue shade and excellent fastness properties. This high-performance dye is valued for its ability to produce vibrant and durable coloration on protein fibers like wool, silk, and nylon. It is a critical component for manufacturers in the textile, leather, and specialty paper industries seeking reliable and consistent blue hues. The compound is supplied under the identifier CAS NO 30586-13-1.

Application

• Textile Dyeing: Primary application for dyeing wool, silk, and polyamide (nylon) fibers, offering good leveling and wash fastness.
• Leather Finishing: Used for coloring leather goods, providing rich and uniform blue tones with good lightfastness.
• Paper Coloring: Employed in the production of specialty and decorative papers where a stable blue color is required.
• Ink Formulation: A component in the manufacture of certain inks for non-impact printing and specialty markers.
• Biological Staining: Potential use as a histological stain in laboratory settings due to its affinity for specific tissue structures.
