Abstract: The present invention provides a metal oxide dispersion comprises a metal oxide, a millbase and a dispersant. The dispersant in the metal oxide is selected from a group consisting of a phosphoric acid polyester copolymer, a trimethoxysilane compound, a triethoxysilanes compound, dimethylamino ethyl methacrylate (DMAEMA) and a combination thereof, and the dispersion is substantially free of water. The metal oxide dispersion of the invention is useful for manufacturing an inkjet ink to provide a high-quality color image on a contact lens or a mold so as to produce a colored contact lens.
