| 摘要 |
<p>A surface derivatizing agent having an α, η-diketo moiety, a beta-hydroxy acid moiety, a hydroxamic acid moiety, a phosphonic acid moiety, or a phenolic moiety, or that is a trimethylsilyl donor, is allowed to contact an aqueous slurry of pigment particles selected from the group consisting of transition metal containing pigment particles, transition metal oxide containing pigment particles, and complexes of transition metals or transition metal oxides, to increase the hydrophobicity of the surface of such particles. The modified pigment particles disperse easily in a wide variety of organic solvents, and provide stable dispersions having a small mean pigment particle size and narrow particle size distribution.</p> |
