Description
A synthetic blue anthraquinone dye. Indanthrone blue was first prepared as an anthraquinone derivative of indigo by Rene Bohn in 1901. He named the colorant indanthrene, but the name was changed to indanthrone when Indanthrene® became a brand name [I.G.Farbenindustrie A.G.] for the colorant. Indanthrone is rarely used as a colorant because it is similar in hue to phthalocyanine blue but is more expensive.
