Anti-reflection member, manufacturing method thereof, and cathode-ray tube
First Claim
1. An anti-reflection optical element comprising;
- a substrate,a hard coat layer,an anti-reflection film having first and second layers,said first layer being formed on said substrate by a PVD method and having a target material of Sn, Zn, In or an alloy consisting of In and Sn, wherein said first layer is a transparent conductive oxide layer containing a material selected from SnO2, ZnO, In2 O3 and ITO, and said second layer has a refractive index which is lower than that of said first layer.

Abstract
A anti-reflection member provided with an antistatic function and an electromagnetic radiation shielding function and having a reflection preventing optical thin film excellent in adhesion with the hard coat layer.
The anti-reflection member comprises a laminate composed of substrate, hard coat layer, and reflection preventing optical thin film having at least two layers, the first layer of the reflection preventing optical thin film provided in contact with the hard coat layer comprises a transparent conductive oxide film (for example, SnO2, ZnO, In2 O3, or ITO) formed by reactive physical vapor phase deposition, and the second layer of the reflection preventing optical thin film consists of a material (for example, SiO2 or MgF2) having a refractive index smaller than that of the first layer.
