Basic Red 12 is a cationic methine dye that produces a brilliant, clean, bluish-red shade, often described as a fuchsine or magenta colour. It is a versatile dye that exhibits a strong affinity for both paper pulp and acrylic fibres, providing high colour value and consistent results. Its primary use is in industrial applications where a bright, vibrant red with a distinct bluish undertone is desired at an economical price point.
