  • Patent number: 9683108
    Abstract: There is provided an antireflective laminate having a low refractive index and excellent mechanical strength, which comprises a coating layer of an ionizing radiation curing-type resin composition comprising ionizing radiation curing group-containing hollow silica fine particles. The antireflective laminate comprises a light transparent base material and at least a low refractive index layer having a refractive index of not more than 1.45 provided on the light transparent base material, wherein the low refractive index layer comprises an ionizing radiation curing-type resin composition and silica fine particles having an outer shell layer with the interior of the silica fine particles being porous or void, and, for a part or all of the silica fine particles, at least a part of the surface of the silica fine particle has been treated with an ionizing radiation curing group-containing silane coupling agent.
