ABSTRACT:
A coating composition and coating for ophthalmic lenses and other polymeric substrates having a unique combination of excellent solution stability, rapid cure rate, improved mar resistance, rapid dye absorption, and improved receptivity towards antireflective coatings. The coating comprises an abrasion resistant polymer and a dye-absorption-enhancing oligomer. The coating is tinted after curing with a dye to provide light absorbency in the coating.
