Description

Vat Blue 14 CAS NO 1324-27-2 is a high-performance vat dye belonging to the anthraquinone chemical class, renowned for its excellent color fastness properties. This compound is critical for achieving deep, durable blue shades that resist fading from washing, light, and perspiration. It is primarily required by manufacturers in the textile industry for dyeing and printing natural fibers like cotton, as well as for specialized applications in the coloration of paper and leather.

Application

• Textile Dyeing: Primary application for dyeing cotton, linen, and other cellulosic fibers to produce wash-fast and light-fast blue hues.
• Textile Printing: Used in printing pastes for creating sharp, durable blue patterns on fabric.
• Paper Coloration: Employed for tinting high-quality papers where color stability is important.
• Leather Finishing: Applied in the dyeing of leather goods to achieve rich, permanent blue colors.
• Industrial Pigmentation: Can be used as a colorant in specific industrial coatings and plastics where vat dye properties are beneficial.
