Abstract
A surface coordinating agent is allowed to contact an aqueous slurry of transition metal-containing pigment particles to increase the hydrophilicity of the surface of such particles. The modified pigment particles disperse easily in a wide variety of solvents, and provide stable, dispersions having a small mean pigment particle size and narrow particle size distribution.
