摘要： An antireflection film is provided which is insoluble, wear-resistant, and weatherable, and simultaneously having non-fogging property. A non-fogging optical member employing the non-fogging antireflection film, and a process for producing the film are also provided. The non-fogging antireflection film is formed from a composition derived by polycondensation of a hydrolyzate of an inorganic alkoxide conducted in the presence of a polyacrylic acid compound.
