Procedure

20 g of C.I. pigment red 122 having an average primary particle diameter of 90 nm (in which the content of metal ions having a valence of at least 2 was 380 ppm), 55 g of the above aqueous dispersion of the pigment derivative (g) and 60 g of deionized water were mixed, aqueous ammonia was added so as to adjust the pH of a mixture liquid to 9.0, and the mixture liquid was dispersed with a paint shaker in the presence of zirconia beads as media for approximately 7 hours, to obtain a water-based pigment dispersion.
