DNA Orange

An organic color pigment used in printing inks. DNA Orange is a reddish orange pigment which possesses high lightfastness, heat resistance, and acid and alkali resistance, and can withstand exposure to waxes and water. It is also highly opaque. However, it does not hold up well when exposed to solvents. Its toxicity remains in doubt. DNA Orange has poor flow characteristics, and is used primarily in inexpensive printing on kraft paper or polyethylene films. (See also Organic Color Pigments.)

Also known as Orange 2G, Dinitroaniline Red, and Permanent Red 2G ('CI Pigment Orange 5 No. 12075').
