Ixone, which is a non–nitrogenous vat dye, the simplest known for so deep a colour as green, contains in its molecule an anthracene ring system capable under the influence of solar radiation of combining with oxygon to give a colourless photo–oxide. The sensitivity of this dye to sunlight n;ay thus be explained, and the hypothesis may be extended to other dyes containing the same structure.
