実験手順

20 g of C.I. pigment yellow 151 having an average primary particle diameter of 80 nm (in which the content of metal ions having a valence of at least 2 was 270 ppm), 4 g of a commercially available dye C.I. acid yellow 23 and 110 g of deionized water were mixed, a 1% sodium hydroxide aqueous solution 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 5 hours, to obtain a water-based 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 bleeding of the dye.
