Participants

Reaction Steps

20 g of C.I. pigment red 122 (in which the content of metal ions having a valence of at least 2 was 385 ppm), 80 g of the above aqueous dispersion of the pigment derivative (g) and 60 g of deionized water were mixed, 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.
