Description

Vat Green 11 is a high-performance vat dye belonging to the anthraquinone chemical class, known for its excellent color fastness and stability. This compound is valued for its ability to produce deep, vibrant green shades that are resistant to light, washing, and chlorine, making it a critical component for demanding textile applications. It is primarily utilized by manufacturers in the textile dyeing and printing industries, as well as in the production of specialty pigments for plastics and coatings where superior durability is required.

Application

• Textile Dyeing: Primary application for dyeing cotton, linen, viscose, and other cellulosic fibers to achieve fast green colors.
• Textile Printing: Used in printing pastes for fabrics requiring high wash and light fastness.
• Pigment Manufacturing: Serves as a colorant intermediate for producing high-quality organic pigments.
• Industrial Coatings: Imparts durable color to industrial paints and coatings.
• Plastics Coloring: Used for coloring polymers and plastics where color stability is essential.
• Leather Dyeing: Applied in the dyeing of leather goods for consistent and lasting green hues.
