Description

Vat Violet 3 is a high-purity vat dye belonging to the anthraquinone chemical class, identified by CAS No. 2379-75-1. It is valued for its excellent color fastness, lightfastness, and chemical resistance, making it a critical component for demanding coloration applications. This pigment is primarily used by manufacturers in the textile, specialty inks, and high-performance plastics industries seeking durable and vibrant violet hues.

Application

• Textile Dyeing: Used for dyeing and printing cotton, wool, and other natural fibers, especially where superior wash and light fastness are required.
• Specialty Inks & Coatings: Employed in the formulation of high-performance inks for security printing, automotive coatings, and industrial paints.
• Plastics and Polymers: Provides coloration for engineering plastics, synthetic fibers (like polyester), and other polymer matrices needing stability during processing.
• Leather Coloring: Used in the dyeing of leather goods to achieve deep, lasting violet colors.
• Paper Staining: Applied for specialty paper products requiring color permanence.
• Research & Development: Serves as a standard or intermediate in chemical synthesis and analytical research within industrial laboratories.
