Description

Directblack114 is a high-performance, synthetic diazo direct dye widely recognized for its deep, intense black shade and excellent substantivity to cellulosic fibers. Its primary value lies in providing a cost-effective and reliable coloring solution with good wash and light fastness properties for industrial dyeing processes. This product is essential for manufacturers in the textile, leather, and paper industries seeking consistent, high-quality black coloration. Directblack114 CAS NO 61703-05-7 is a key component in formulations requiring a strong, direct black dye with good build-up and leveling characteristics.

Application

• Primary dyeing of cotton, viscose, rayon, and other cellulosic textiles.
• Coloration of paper products, including specialty papers and packaging materials.
• Dyeing of leather goods to achieve uniform and deep black finishes.
• Used in the formulation of inkjet inks and other specialty colorant systems.
• As a colorant for wood staining and other non-textile substrates.
• In educational and research laboratories for dye chemistry studies and experiments.
