Description

Vat Violet 1 CAS NO 1324-55-6 is a synthetic organic pigment belonging to the vat dye class, known for its excellent color fastness and stability. This compound is valued for its ability to produce a deep, rich violet hue that is resistant to fading from light, washing, and chemicals. It is primarily required by manufacturers in the textile, ink, and specialty coatings industries seeking durable and high-performance colorants for their products.

Application

• Primary dyeing and printing of cellulose fibers such as cotton, viscose, and linen.
• Coloration of industrial fabrics requiring high lightfastness and washfastness, including awnings, tarpaulins, and workwear.
• Manufacturing of artist's pigments and high-quality inks for security printing and archival documents.
• Production of specialty paints and coatings for automotive, marine, or outdoor applications where color durability is critical.
• Potential use as a colorant for plastics and masterbatches, subject to compatibility and thermal stability testing.
• Research and development applications in organic semiconductor materials or as a chemical intermediate in synthesis.
