Solvent Yellow 163 is a high-performance solvent dye from the anthraquinone class, known for its bright, reddish-yellow shade. It exhibits excellent heat stability and lightfastness, making it particularly suitable for coloring engineering plastics that are processed at high temperatures. It is a preferred choice for the spin dyeing of polyester (PET) and for coloring polyamide (PA), providing a vibrant and highly durable color.
