Description

C.I. Acid Blue 130 is a synthetic acid dye belonging to the anthraquinone class, valued for its bright and stable blue hue. It is a critical component for achieving high-quality, durable coloration on protein-based substrates like wool, silk, and nylon. This dye is essential for manufacturers in the textile, leather, and specialty paper industries seeking consistent, vibrant blue shades with good fastness properties. Its reliable performance makes it a staple in formulations requiring precise color matching and batch-to-batch consistency.

Application

• Textile Dyeing: Primary application for dyeing wool, silk, and polyamide fibers (nylon) to achieve vibrant blue colors.
• Leather Finishing: Used in the coloration of leather goods, providing rich and even blue tones.
• Paper Staining: Employed for specialty paper products, including decorative papers and security papers requiring specific colorants.
• Ink Formulation: A colorant component in certain types of inks, particularly for non-impact printing or specialty applications.
• Biological Staining: Potential use as a histological stain in laboratory settings for microscopic analysis.
• Polymer Coloring: Can be used for mass coloration of specific synthetic polymers compatible with acid dyes.
