Patent ID: 7887910

Claim:
A laminated optical element comprising: an optical substrate made of an optical material; an intermediate layer provided on the optical substrate; and an optical resin layer provided on the intermediate layer, wherein the optical resin layer is made of a resin composed of an organometallic polymer having an -M-O-M- bond (M is a metal atom), a metal alkoxide and/or a hydrolysate thereof having only one hydrolyzable group, and an organic polymer having a urethane bond and a methacryloxy group or an acryloxy group, and wherein the intermediate layer has a microparticle layer obtained by dispersing metal oxide microparticles in a matrix resin composed of a metal alkoxide and/or a hydrolysate thereof having a radical polymerizable group and a hydrolyzable group; and, wherein the intermediate layer has a laminate structure comprising at least two layers, at least one of which is the microparticle layer.
