Method for making colored contact lenses and color coating composition |
| abstract |
The invention relates to a procedure for staining a contact lens, wherein at least part of the surface of the lens consisting of a polymer containing hydroxyl and/or carboxyl groups is coated with a colour coating containing as polymer-cross-linking agent a compound with at least two urethane groups or a mixture of such compounds, and urethane exchange is effected for causing cross-linking of polymers, by reacting the urethane groups with the hydroxyl and/or carboxyl groups of the bonding agent polymer and of the lens polymer. |
