Procedure

1,2,3,4-Tetrafluoroanthraquinone and 25 g of 3-chloro-4-cyanoaniline were charged in a 50 cc, four necked flask and then the reaction was carried out at 150° C. for about 8 hours. After completion of reaction, 3-chloro-4-cyanoaniline was distilled out from the reaction solution and a column purification using a column with a silica gel was effected to give rise to 1.14 g of 2,3-bis(3-chloro-4-cyanoanilino)-1,4-difluoroanthraquinone (Dye 22') (yield 29.3 mol %). The physical properties of Dye 22' and analytical values defining the compound are tabulated in Table 23.
