Solvent Red 52 is a high-performance solvent dye from the anthraquinone class. It is renowned for its bright, clean, bluish-red shade and its excellent heat stability and lightfastness. Its robust anthraquinone structure allows it to withstand the high processing temperatures of engineering plastics like polycarbonate (PC) and PMMA, making it a preferred choice for demanding applications where color purity and durability are essential.
