ルへの濡れが向上したことを意味する。The flushing time of the pigment composition of Example 1 was shorter than that of the pigment composition of Comparative Example 1 and the pigment composition of Comparative Example 2. The coloring degree of the flushing wastewater is
The pigment of Example 1 was the smallest. This means that the surface treatment of the organic pigment with the ester compound (A) improved the wetting of the ink pigment into the ink vehicle.

ことがわかる。As for the fluidity, the pigment composition of Example 1 was the best in comparison with the pigment compositions of Comparative Example 1 and Comparative Example 2. The gloss was higher in Example 1 than in Comparative Examples 1 and 2. From these facts, it can be seen that, in the case of the azo lake pigment, not only the ink fluidity is improved, but also the gloss is improved and the flushing time at the time of preparing the ink is shortened.
