Description

Disperse Red 11 is a synthetic anthraquinone derivative dye widely used for its vibrant red color and excellent fastness properties. This high-performance colorant is essential for achieving durable and consistent coloration in hydrophobic synthetic fibers. It is a critical raw material for manufacturers in the textile and plastics industries who require reliable, high-quality dyes for polyester, acetate, and nylon. The compound is supplied under the identifier CAS NO 2872-48-2.

Application

• Primary dyeing and printing of polyester fibers and fabrics.
• Coloration of acetate and triacetate textiles.
• Mass coloration (dope dyeing) of synthetic polymers including certain nylons.
• Manufacturing of transfer papers for sublimation printing applications.
• Production of colored plastics and masterbatches for engineering resins.
• As a colorant for specialty inks and coatings.
