摘要：
This invention provides a coating composition which utilizes a free radical initiator and an organic tintability additive which remains substantially unpolymerized even after the remainder of the coating composition is cured. Superior tintability and adhesion to polycarbonate makes this coating particularly suitable for making tinted opthalmic lenses.
