Reactive Yellow 42 is a disazo reactive dye known for its good overall fastness properties, often referred to as a “milling” type reactive dye. It produces a neutral to slightly greenish-yellow shade with good resistance to washing and light. This makes it a suitable choice for dyeing items that require higher durability than standard reactive dyes, such as workwear, towels, and home furnishings made from cotton or viscose.
