Aggregation behavior of C.I. Direct Blue 86 was discussed using analyses of its UV-Vis spectra. The experiment results show that the dye molecules are inclined to aggregate in aqueous solution. Even in a very dilute solution of 0.050 μol/L, A618/A659 = 1. 239 8, showing that the dye monomers still coexist with its dimers. The strong aggregation trend may cause dye precipitates at a higher concentration, which is an important factor that should be considered in producing a formula of ink-jet inks containing the dye as a colorant.
