Description

C.I.Acid Blue 167 is a synthetic acid dye belonging to the anthraquinone chemical class, valued for its bright and stable blue hue. It is a critical component for achieving deep, wash-fast coloration on protein-based fibers like wool, silk, and nylon. This dye is essential for manufacturers in the textile, leather, and specialty paper industries seeking reliable and vibrant blue shades for their products.

Application

• Textile Dyeing: Primary application for dyeing wool, silk, and polyamide (nylon) fibers, offering excellent levelness and fastness properties.
• Leather Finishing: Used for coloring leather goods, providing rich and uniform blue tones with good adhesion.
• Paper Staining: Employed in the production of specialty papers, decorative papers, and security papers requiring colorfast blue elements.
• Ink Formulation: A colorant for certain types of inks, particularly where acid dye compatibility is required.
• Biological Staining: Potential use as a histological stain in laboratory settings due to its affinity for protein structures.
