<P>PROBLEM TO BE SOLVED: To provide an antireflection coating, its manufacturing method and an article with an antireflection coating with the antireflection coating formed thereon which has a high level antireflection function even though a fluorine compound is not contained, is cured by irradiation with active energy rays, and is superior to high hardness, transparency, adhesiveness, treatment cost and treatment time. <P>SOLUTION: In the coating, a layer with a high refractive index composed of a cured product of a coating agent containing (A) metal oxide fine particles selected from titanium oxide, aluminum oxide, zirconium oxide, cerium oxide, iron oxide, tin oxide and a compound of these oxides, (B) a compound with a group selected from an acrylic group, a mathacrylic group, a vinyl group and a styryl group, and/or (C) a compound with two or more groups selected from an epoxy group and an oxetane group; and a layer with a low refractive index composed of a cured product of a coating agent containing (D) silica-based inorganic oxide fine particles with an inside cavity, (B) the compound with the group selected from the acrylic group, the mathacrylic group, the vinyl group and the styryl group, and/or (C) the compound with two or more groups selected from the epoxy group and the oxetane group are successively laminated. The coating has an antireflection ability with a high level. <P>COPYRIGHT: (C)2004,JPO |
