    • A colorant dispersion for an ink includes a liquid medium and metal oxide particles dispersed in the liquid medium. The metal oxide particles include a mixture of i) metal oxide particle cores having an organic ligand interacted with respective surfaces thereof, ii) metal oxide particle cores having the organic ligand chemically bonded to respective surfaces thereof, and iii) products of a reaction between metal ions on respective surfaces of metal oxide particle cores and the organic ligand. The organic ligand is chosen from an organic ligand having a phenol group, an organic ligand having a carboxylate group, an organic ligand having an amine group, or combinations thereof. The metal oxide particles exhibit a color that is different from a natural color of the metal oxide particle core.
    • 用于油墨的着色剂分散体包括液体介质和分散在液体介质中的金属氧化物颗粒。 金属氧化物颗粒包括i)具有与其各自表面相互作用的有机配体的金属氧化物颗粒芯的混合物,ii)具有与其各自表面化学键合的有机配体的金属氧化物颗粒芯,和iii)金属 金属氧化物颗粒芯和有机配体的各自表面上的离子。 有机配体选自具有酚基的有机配体,具有羧酸基的有机配体,具有胺基的有机配体或其组合。 金属氧化物颗粒表现出与金属氧化物颗粒芯的天然色不同的颜色。
