Abstract:
1. An antireflection film, comprising a substrate coated with a film composed of a first film compound having a first functional group and a transparent fine particle layer formed of arranged transparent fine particles each coated with a film composed of a second film compound having a second functional group and bound and fixed to a surface of the substrate, wherein: the coated transparent fine particle is fixed to the coated substrate via bond formed by coupling reactions between the first functional group and a coupling agent and between the second functional group and the coupling agent, and the coupling agent has at least one first coupling reactive group that forms a bond through a coupling reaction with the first functional group and at least one second coupling reactive group that forms a bond through a coupling reaction with the second functional group, and each of the bonds formed by the coupling reactions is an N—CH
