Abstract: Provided is an antireflection film obtained by laminating, in succession, a transparent substrate, a first layer, and a second layer having a lower refractive index than the refractive index of the first layer. The first layer is obtained by curing a film containing an ionizing radiation-curable material, a quaternary ammonium salt material, a leveling agent, and a solvent, and has a structure wherein a middle layer, hard coating layer and recoating layer are laminated in succession from the transparent substrate side. The recoating layer does not contain a quaternary ammonium salt. The hard coating layer contains a quaternary ammonium salt, and the concentration of the quaternary ammonium salt in the hard coating layer gradually increases from the middle layer side to the recoating layer side.
