ANTIREFLECTION FILM, OPTICAL ELEMENT AND IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an antireflection film having an antireflection layer formed to have a good stain resistance (particularly dust wiping property).

SOLUTION: This antireflection film includes a hard coating layer provided directly on or via the other layer on one surface of a transparent substrate, the antireflection layer laminated on the front surface of the coating layer. The antireflection film is a dry cured film formed of at least two types of low refractive index materials each of which satisfies a refractive index:nd20≤1.49 of a material (A) containing a polysiloxane structure as a main component and a material (B) containing a fluorine-containing material as a main component in such a manner that an amount of tribocharging (A) generated when the surface of the antireflection layer is rubbed with steep wool is -1 to +2 kV.
