Description

Vat Violet 13 is a high-performance vat dye belonging to the anthraquinone chemical class, known for its excellent color fastness and stability. This pigment is valued for its ability to produce deep, vibrant violet shades that are highly resistant to light, washing, and chemical degradation. It is primarily required by manufacturers in the textile industry for dyeing and printing natural fibers like cotton, as well as by producers of specialty inks and high-grade artists' pigments.

Application

• Dyeing of cotton, wool, and other natural cellulosic fibers to achieve violet shades with superior wash and light fastness.
• Textile printing applications for fashion and home furnishings requiring durable color.
• Manufacturing of specialty inks, including security inks and high-performance printing inks.
• Production of high-quality artists' pigments and colorants for fine arts.
• Coloration of paper and leather where color stability is critical.
• Potential use as an intermediate or colorant in the synthesis of other complex organic compounds.
