Method of forming antireflective coatings

摘要

An antireflective coating may be formed on visible light transmitting materials. The antireflective coating may a stack of two coating layers. The first coating layer may be formed from a composition that includes a metal alkoxide. The first coating layer may be cured by the application of ultraviolet light or heat. The second coating layer may be formed from a second composition that includes an initiator and an ethylenically substituted monomer. The second composition may be cured by the application of ultraviolet light. The antireflective coatings may be applied to a plastic lens or a plastic lens mold.
