Acid Yellow 42 is a high-performance milling acid dye known for its excellent fastness properties and strong colour value. As a disazo dye, it gives superior durability compared to many monoazo types, making it ideal for applications requiring high wash fastness and light fastness. It gives a bright, greenish-yellow shade and exhibits good levelling properties on wool and nylon. Its robust performance makes it a preferred choice for high-quality textiles, premium leather, and specialty papers.
