Indanthrone blue introduction

Indanthrone blue, also called indanthrene, is an organic dye made from 2-aminoanthraquinone treated with potassium hydroxide in the presence of a potassium salt. It is a pigment that can be used in the following mediums: acrylic, alkalyd, casein, encaustic, fresco, gouache, linseed oil, tempera, pastel, and watercolor painting. It is used to dye unmordanted cotton and as a pigment in quality paints and enamels. As a food dye, it has E number E130, but it is not approved for use in either the United States or the European Union.[1][2] Indanthrene Blue RS was patented in 1901 by Rene Bohn as the first anthraquinone vat dye, one of the dyes with very good fastness to light and washing.
