Optical functional element and method of producing the same

摘要

The optical functional element contains aggregates of developed silver grains obtained by developing silver halide grains arranged so as to constitute a periodical structure. The element includes a substrate and a medium layer The aggregates of the developed silver grains are arranged in the medium layer so as to constitute said periodical structure. The element is produced by first selectively exposing a photo-curing resin layer formed on said substrate in which the silver halide grains are dispersed so as to selectively photo-cure the photo-curing resin layer, then overall exposing the photo-curing resin layer to expose the silver halide grains in the photo-curing resin layer, and thereafter developing the photo-curing resin layer.
