Title:
ANTIREFLECTION FILM
Document Type and Number:
Japanese Patent JP2013104959
Kind Code:
A
Abstract:

To provide a manufacturing method of an antireflection film having an excellent optical characteristics, which can provide a multilayer construction in one coating process.

An antireflection film comprises: a transparent base material; a hard coat layer which is laminated on the transparent base material; and an antireflection layer which is laminated on the hard coat layer. The hard coat layer is a mixed layer in which components of the transparent base material and a binder matrix are mixed. The antireflection layer includes, in an order from the hard coat layer side, a high refractive index layer in which the binder matrix is locally present and a low refractive index layer in which low refractive index particles are locally present, with the refractive index of the high refractive index layer being in the range of 1.51-1.58, the refractive index of the low refractive index layer being in the range of 1.29-1.43, and the optical film thickness of the low refractive index layer is in the range of 110 nm to 140 nm.
