Abstract:
1. An optical layered body comprising a light-transmitting substrate and a low refractive index layer, formed on the light-transmitting substrate, wherein 1) the low refractive index layer is formed on the outermost surface, and 2) the low refractive index layer contains an antistatic agent in an amount in the low refractive index layer of 0.5 to 30% by weight, wherein said antistatic agent contains a reaction group in the molecule, wherein the low refractive index layer is formed from a composition that contains silica particles having voids, pentaerythritol triacrylate, a polymerization initiator, the antistatic agent and at least one member selected from the group consisting of a thermoplastic resin, a thermosetting resin, an ionizing radiation-curable resin and an ionizing radiation-curable compound.
