Widely used in the dyeing of synthetic fibers, especially polyester and acetate. Provides bright blue shades with good lightfastness and wash resistance. Commonly applied in textile industries for coloring fabrics used in apparel, home textiles, and industrial materials. Also used in some ink formulations and for coloring plastics where a blue dispersion dye is suitable. Not suitable for natural fibers due to its insoluble nature and reliance on high-temperature dyeing processes.
