Abstract:
The present invention provides inks and methods for making colored silicone hydrogel contact lenses. The ink of the invention comprises an actinically-curable binder copolymer comprising fluorine-containing segments and is characterized by having capability to be cured actinically or thermally to form a colored film on a molding surface of a mold or a silicone hydrogel contact lens and by having an increased durability in a solvated state in a silicone-hydrogel lens formulation in relation to a control colored film obtained from a control ink including an actinically-curable fluorine-free binder copolymer. The invention also provides methods for making colored silicone hydrogel contact lenses based on print-on-mold processes for producing colored contact lenses.
