Description

Acid Blue 260 is a synthetic acid dye belonging to the anthraquinone class, known for its bright and stable blue hue. This high-performance colorant is valued for its excellent light and wash fastness properties, making it a critical component for demanding dyeing applications. It is primarily used by manufacturers in the textile, leather, and paper industries seeking vibrant, durable coloration.

Application

Acid Blue 260 is engineered for applications requiring robust color performance. Its primary and related uses include:

• Textile Dyeing: For dyeing polyamide (nylon), wool, and silk fibers to achieve brilliant blue shades with high fastness.
• Leather Coloring: Used in the dyeing of leather goods, providing rich color penetration and stability.
• Paper Staining: Employed in the production of specialty papers, including decorative and security papers.
• Ink Formulation: As a colorant in certain types of inks where acid dye compatibility is required.
• Biological Staining: Potential use as a histological stain in laboratory settings, owing to its affinity for protein fibers.
