Abstract
The present invention provides an ink and a method of using the ink for making colored contact lenses. The ink comprises at least one colorant, a silicone-containing binder polymer, a solvent, a vinylic-monomer mixture, and optionally a photoinitiator or thermal initiator. The silicone-containing binder polymer is a copolymerization product of a polymerizable mixture including (i) at least one hydrophilic vinylic monomer; (ii) at least one functionalizing vinylic monomer containing at least one functional group selected from the group consisting of hydroxyl group —OH, amino group —NHR (wherein R is hydrogen or C1 to C8 alkyl), carboxylic group —COOH, epoxy group, amide group —CONHR, and combinations thereof; (iii) at least one silicone-containing vinylic monomer or macromere.
