Patent number: 7354959Abstract: The present invention is related to water-based inks for making colored hydrogel contact lenses, in particular, colored HEMA-based hydrogel contact lenses. The ink of the invention comprises at least one colorant, water, and a water-soluble and actinically-curable binder polymer which is a vinyl group-terminated polyurethane polymer, a vinyl group-terminated polyurea binder polymer, or a mixture thereof. Also, the ink of the invention is characterized by having a viscosity greater than 50 centipoise (cps), a prolonged stability, and a good adhesion to a HEMA-based hydrogel contact lens. The ink of the invention preferably further has a good compatibility with a HEMA-based hydrogel material, and/or good transferability from a mold to a HEMA-based hydrogel contact lens made in the mold. The present invention is also related to a method for making colored hydrogel contact lenses using an ink of the invention.Type: GrantFiled: October 12, 2005Date of Patent: April 8, 2008Assignee: Novartis AGInventors: Robert C. Tucker, Sandra Corti, Joshua Wallach

Patent number: 7312255Abstract: The invention relates to a mixture for the application of a polymeric coating to a substrate. Said mixtures comprises water and optionally an organic solvent, at least one water-dispersible radically polymerizable compound, at least one water-dispersible polymerizable crosslinking compound and at least one water-dispersible compound which forms free radicals upon exposure to actinic radiation. The radically polymerizable compound cannot fully set with the free radicals formed on irradiation at room temperature, but rather comprises further reactive bonds, which lead to further or complete setting with the crosslinking compound. The invention further relates to a method for application of a non-adhesive corrosion protection layer to a substrate, by application of a mixture to the surface of a metallic or polymeric substrate, drying the mixture and irradiation of the applied coating with actinic radiation of such an intensity and for such a period that a solid, hard, tough coating is formed.Type: GrantFiled: March 2, 2002Date of Patent: December 25, 2007Assignee: Chemetall GmbHInventor: Georg Gros
