Antireflection film and polarizing plate and image display device using same

An antireflection film comprising:

• a low refractive index layer containing fine pores;
• and
• an antistatic layer,
• wherein the low refractive index layer is in direct contact with the antistatic layer,
• wherein, when a surface of the antireflection film is brought into contact with water for 15 minutes, a wiped portion of the surface shows a chromaticity change, ΔE, of 0.45 or less in the CIE 1976 L*a*b* color space measured under a standard illuminant D65,
• wherein the low refractive index layer containing fine pores comprises inorganic fine particles having an adsorbed water amount of 6.1% by weight or less and having a particle size of from 5 to 100 nm,
• wherein the inorganic fine particles comprises porous inorganic fine particles, hollow inorganic fine particles or a combination thereof,
• wherein said low refractive index layer is formed from at least a monomer having two or more ethylenically unsaturated groups in one molecule, and the inorganic fine particles,
• wherein a limit load after exposure to ozone of the antireflection film is at least about 1000 g.
