Pigment Red 22 is a red powder also known as "Fast Brilliant Red N". Pigmentred is a naphthol derivative that is used in textile printing, water-based inks, solvent-based inks, as well as, self-drying inks and latex paints. Pigment Red 22 is also used as a tattoo ink. The reduction of dithionite in Pigment Red 22 produces 2,4-toluylenediamine, a highly toxic compound.
