Abstract:
A method for producing an optical article. A first layer that is light-transmissive is formed on an optical substrate directly or with an additional layer in between. A silicide material, light-transmissive thin film is formed on the surface of the first layer.
Abstract:
A method for producing an optical article includes: forming a first layer that is light-transmissive on an optical substrate directly or with another layer in between; and reducing the resistance of at least a portion of a surface layer of the first layer by ion-assisted deposition of at least one composition selected from the group consisting of titanium, niobium, oxides of titanium, and oxides of niobium.
Abstract:
A process for producing an optical article having an antireflection layer formed directly or via another layer on a flexible optical base material, includes: forming a primary layer contained in the antireflection layer; and adding at least any one of carbon, silicon, and germanium to a surface of the primary layer to reduce a resistance.

Abstract:
A method for producing an optical article having a filter layer formed directly or with another layer in between on an optical substrate, the filter layer transmitting light in a predetermined wavelength band and blocking light with a wavelength longer and/or shorter than the predetermined wavelength band, includes: forming a first layer to be included in the filter layer, and adding at least one of carbon, silicon, and germanium to the surface of the first layer, thereby reducing the resistance of the surface of the first layer.
Abstract:
A process for producing an optical article having an antireflection layer formed directly or via another layer on an optical base material, includes: forming a primary layer contained in the antireflection layer; and forming a light transmissive conductive layer containing a metal containing germanium as a main component and/or a compound of germanium and a transition metal on a surface of the primary layer.

A multilayer antireflection layer includes a high refractive index layer and a low refractive index layer that are laminated alternately, the high reflective index layer having a grain boundary, and particles forming the grain boundary having an average particle diameter of 30 nm or less.
Abstract:
An optical article includes: an optical base material; a primer layer formed on the optical base material; a binder layer; and a hardcoat layer formed on the primer layer via the binder layer, the primer layer having a thickness of at least 700 nm, the binder layer having a lower refractive index than the refractive index of the primer layer and the refractive index of the hardcoat layer, and the binder layer having a thickness of at least 35 nm.
Abstract:
An optical article includes an antireflection coating that is configured from alternately laminated n+1 low-refractive-index layers and n high-refractive-index layers (where n is an integer of 2 or more) . At least one of the n high-refractive-index layers is a first-type layer formed by vapor deposition using only a first deposition source that includes zirconium oxide as the main component. The remaining layers) in the n high-refractive-index layers is a second-type layer (s) formed by vapor deposition using only a second deposition source that includes titanium oxide as the main component. The n+1 low-refractive-index layers are third-type layers formed by vapor deposition using only a third deposition source that includes silicon oxide as the main component. The proportion of the total thickness of the second-type layer (s) in the total thickness of the n high-refractive-index layers is from 15% to 90%.
