Description

Acid Blue 119 is a synthetic anthraquinone-based acid dye known for its bright and stable blue color. This high-performance dye is valued for its excellent fastness properties, including good lightfastness and washfastness, making it a reliable choice for demanding applications. It is primarily used in the textile industry for dyeing protein fibers like wool and silk, as well as polyamide fibers such as nylon, and finds additional use in leather and paper coloration. Acid Blue 119 CAS NO 1324-80-7 is supplied as a high-purity powder to ensure consistent and reproducible dyeing results.

Application

• Dyeing of natural protein fibers including wool and silk.
• Coloration of synthetic polyamide fibers, particularly nylon for apparel and carpets.
• Leather dyeing for footwear, garments, and upholstery.
• Paper coloration for specialty and decorative papers.
• Ink formulation for specific printing applications.
• As a colorant for certain types of anodized aluminum.
