ANTIREFLECTION FILM AND METHOD FOR PRODUCING THE SAME

摘要

Disclosed is an antireflection film comprising a transparent supporting body and an organic-inorganic composite layer directly bonded to the surface of the transparent supporting body. In this antireflection film, the surface of the organic-inorganic composite layer is subjected to a water- and oil-repellent treatment. The refractive index of the transparent supporting body is not less than 1.57. The organic-inorganic composite layer contains an organic portion composed of the polymer of a graft polymer chain and an inorganic portion composed of a crosslinked structure formed by hydrolysis and condensation polymerization of an alkoxysilane. The refractive index of the organic-inorganic composite layer is within the range of 1.35-1.49.
