실험 절차

20 g of C.I. pigment red 122 (in which the content of metal ions having a valence of at least 2 was 400 ppm), 60 g of the same aqueous dispersion of the pigment derivative (g) as obtained in Example 43 and 60 g of deionized water were mixed, 9 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 water-based pigment dispersion.
