Epoxy-functional composition that protects dyes from photodegradation and cured coatings made from the composition

摘要

The present invention provides at least one dye having a conjugated chromophore that at least partially suppresses transmission of light within a wavelength range of 400 nm to 500 nm, and one or more dyes containing at least one alicyclic group or aryl group. A coating composition for an optical filter, which comprises an epoxy compound, wherein the ratio of the number of carbon atoms / the number of oxygen atoms in the epoxy compound is 3 or more, and the dry extraction of such an epoxy compound present in the composition is performed. The composition weight is greater than 33% of the dry extract weight of the composition. The coating composition can be applied on the major surface of the substrate of the optical article.
