Description

Acid Blue 113 is a synthetic acid dye belonging to the anthraquinone class, valued for its bright, clear blue shade and good lightfastness. It is a critical component for achieving durable and vibrant coloration on protein fibers like wool, silk, and nylon. This dye is essential for manufacturers in the textile and leather industries seeking high-quality, consistent colorants for their products. Its specific chemical identity is confirmed by CAS No. 3351-05-1.

Application

• Textile Dyeing: Primary application for dyeing wool, silk, and polyamide (nylon) fibers to achieve a bright blue color with good wash and light fastness.
• Leather Coloring: Used in the dyeing of leather goods, providing rich and penetrating blue shades.
• Paper Staining: Employed for specialty paper coloring where a specific blue hue is required.
• Ink Formulation: A colorant component in the manufacture of certain inks, particularly for non-food contact 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.
