Coating composition and lens coated therewith

摘要

There are provided a coating composition, for use on a plastic lens with a refractive index exceeding 1.60, for avoiding interference fringes and unevenness in the reflected color, and a lens coated with such coating composition. The coating composition contains an organic silicon compound represented by R<1>aR<2>bSi-(OR<3>)4-(a+b) and modified sol of a double structure in which nuclei composed of tin oxide colloid particles are surrounded by tin oxide-tungsten oxide complex colloid particles, and the plastic lens is coated with such coating composition.
