    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.

    Abstract: The present invention provides an actinically or thermally curable ink for making colored silicone hydrogel contact lenses. The ink of the invention comprises at least a pigment, a polymeric dispersant, a solvent and an actinically or thermally curable silicone-containing binder polymer including ethylenically unsaturated groups and segments derived from at least one silicone-containing vinylic monomer or macromere. The ink of the invention is characterized by having capability to be cured actinically or thermally to form a colored coat on a silicone hydrogel contact lens, wherein the ink is characterized by having an longer print life using a pad-printing system by at least 30% comparing to the ink which has the same composition except of no polymeric dispersant, wherein ink life is a number of printed parts that can be achieved in a print cycle.
