1. Colored pigment particles comprising:
(i) a silica and/or silicate material having a negative zeta potential; (ii) an anionic dye; and (iii) a quaternary ammonium compound; wherein: a ratio of the quaternary ammonium compound to the silica and/or silicate material is in a range from about 1% to about 400% of the amount, by weight, of the quaternary ammonium compound sufficient to achieve a zero mV zeta potential of a 1 wt. % mixture of the dry silica and/or silicate material in deionized water; and a weight ratio of the anionic dye is in a range from about 0.01:1 to about 0.72:1, based on the weight of the quaternary ammonium compound. |
