Procedure

20 g of C.I. pigment orange 60 having an average primary particle diameter of 85 nm (in which the content as metal ions having a valence of at least 2 was 320 ppm), 1.6 g of the pigment derivative (a′) and 110 g of deionized water were mixed, triethanolamine was added so as to adjust 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 5 hours, to obtain a pigment dispersion. The obtained water-based pigment dispersion was diluted so as to have a concentration of 3% by weight, and the diluted water-based pigment dispersion was dropped to NO.2 filter paper, to show no bleedings of the pigment derivative.
