Solvent Yellow 33 is a high-performance solvent dye from the quinoline class, renowned for its excellent heat stability and good lightfastness. It produces a brilliant, clean, greenish-yellow shade. Unlike many standard azo dyes, its robust structure allows it to withstand the high processing temperatures of engineering plastics like polycarbonate (PC) and polymethyl methacrylate (PMMA), making it a preferred choice for demanding applications.
