Versuchsvorschrift

2 g of 1,2,3,4-Tetrafluoroanthraquinone, 35 g of 3,4-dicyanoaniline and 60 ml of α-chloronaphthalene were charged in a 200 cc, four necked flask and then the reaction was carried out at 180° C. for about 9 hours. After completion of reaction, 3,4-dicyanoaniline and α-chloronaphthalene were distilled out from the reaction solution and then a column purification using a column with a silica gel was effected to give rise to 2.95 g of 2,3-bis(3,4-dicyanoanilino)-1,4-difluoroanthraquinone (Dye 26') (yield 78.5 mol %). The physical properties of Dye 26' and analytical values defining the compound are tabulated in Table 23. Its UV spectral is shown in FIG. 6.
