Antireflection film and antireflection layer-affixed plastic substrate
First Claim
1. An anti-reflection film comprising a hard-coat layer formed on a substrate, and laminated layers of transparent, high index of refraction oxide layers and transparent, low index of refraction oxide layers laminated on top of each other on the hard-coat layer, characterized in that at least one of the transparent, high index of refraction oxide layers comprises an Nb2O5 layer formed by a reaction sputtering method.

Abstract
A colorless antireflection film excellent in productivity and high in transparency, and an antireflection layer-affixed plastic substrate. An antireflection film and an antireflection layer-affixed plastic substrate having moisture-proofing and gas-barrier properties and being excellent in optical characteristics. An antireflection film comprising a hard coat layer formed on a substrate, and a transparent, high-refractive-index oxide layer and a transparent, low-refractive-index oxide layer alternately laminated on the hard coat layer. The transparent, high-refractive-index oxide layer is compose of a Nb2O5 layer formed by a reactive sputtering method. An antireflection film using a substrate consisting of an organic material, wherein an inorganic, moisture-proofing layer having a refractive index approximate to that of the organic material is formed in contact with one surface of the substrate.
