    摘要: According to the invention, a process for the preparation of triphendioxazines systemetrically or asymmetrically amidated on both sides comprises reducing a triphendioxazine chromophore, which is optionally already amidated on one side, to give the leuco form end amidating and re-oxidizing the leuco form. Products amidated on both sides are obtained in this manner with a high yield and product quality. Novel triphendioxazine dyestuffs are furthermore prepared in this manner.
