Procedure

20 g of C.I. pigment red 264 (in which the content of metal ions having a valence of at least 2 was 520 ppm), 60 g of the same aqueous dispersion of the pigment derivative (n) as that obtained in Example 45 and 60 g of deionized water were mixed, 11 g of 2% by weight triethanolamine was added so as to adjust the neutralization ratio of the pigment derivative to 100%, and the mixture was dispersed with a paint shaker in the presence of zirconia beads as media for approximately 7 hours, to obtain a pigment dispersion.
