Direct Red 111 is a stilbene-class direct dye that produces a bright, pinkish-red shade. It is a highly versatile and economical colorant primarily used in the paper industry. Its strong affinity for cellulosic fibres and its vibrant hue make it an excellent choice for colouring various grades of paper and paperboard, especially where a bright, clean, and eye-catching colour is desired for packaging or decorative purposes.
