Description

C.I.Vat Violet 1:1 is a high-performance vat dye belonging to the anthraquinone chemical class. This pigment is valued for its excellent color fastness properties, particularly its superior resistance to light, washing, and chlorine bleaching. It is primarily used by manufacturers in the textile industry for dyeing and printing cellulosic fibers like cotton, as well as for specialized applications requiring durable coloration. The compound is supplied under the CAS registry number 53027-59-1.

Application

• Textile Dyeing: Primary application for dyeing cotton, viscose, and other cellulosic fibers to achieve deep, fast violet shades.
• Textile Printing: Used in printing pastes for fabrics, offering sharp prints with excellent wash and light fastness.
• Yarn Dyeing: Suitable for dyeing yarns intended for high-quality denim, workwear, and home textiles.
• Pigment Manufacturing: Can be used as a precursor or component in the production of high-performance organic pigments.
• Specialty Applications: Potential use in the coloration of paper or for technical applications where chemical resistance is required.
