Abstract
The claimed invention provides an antireflection film including a light-transmitting substrate, a hard coat layer, and a low-refractive-index layer, the hard coat layer and the low-refractive-index layer being formed on the light-transmitting substrate, the low-refractive-index layer including a (meth)acrylic resin, hollow silica particles, reactive silica particles, and two kinds of antifouling agents, the hollow silica particles having an average particle size of 40 to 80 nm and a blending ratio to the (meth)acrylic resin, represented by a ratio: Amount of hollow silica particles/Amount of (meth)acrylic resin, of 0.9 to 1.4, the amount of the reactive silica particles being 5 to 60 parts by mass based on 100 parts by mass of the (meth) acrylic resin, the antifouling agents including an antifouling agent that contains a fluorine compound and an antifouling agent that contains a fluoro-silicone compound.
