                 Abstract: Based on the principle of like dissolves like, 1,4-diamino-2,3-dicarboxylic anhydride anthraquinone
                 was used as raw material to prepare eight oil-soluble 1,4-diamino-2,3-phthalimide anthraquinone dyes by
                 substitution  reaction  with  primary  amines  of  different  carbon  chain  lengths.  The  solubility  and  UV
                 absorption properties of the synthesized 8 dyes in common organic solvents were tested. The results show
                 that the maximum absorption wavelength of the eight products was in the range of 669~672 nm, which
                 was not affected by the alkyl chain length. The oil solubility of dyes was significantly improved compared
                 with  that  of  1,4-diamino-2,3  dicarboxylic  anhydride  anthraquinone.  Among  them,  1,4-diamino-2,3-
                 dicarboxylic anhydride anthraquinone was insoluble in tetrahydrofuran, and product Anthra-n-6 (n-hexylamine
                                                                                         3
                 substituted)  had  the  highest  solubility  in  tetrahydrofuran,  which  reached  9 × 10  g/mL  (25  ℃ ).
                 1,4-Diamino-2,3-dicarboxylic  anhydride  anthraquinone  was  not  used  as  printing  dye,  while  Anthra-n-6
                 exhibited the best printing effect. The printed density value was 1.17, L, a and b values were 79.7, 10.2,
                 and 25.9, respectively.
