Abstract
Provided are an optical member having abrasion resistance and transparency and a method of producing the optical member. The method of producing the optical member includes coating a coating material containing hollow particles and a solvent on a substrate and further coating a coating material containing a binder and a solvent to form a film in which the binder lies between the hollow particles; and then drying the film.
Claims16
A method of producing an optical member, comprising:
- forming an antireflection film on a substrate, wherein forming the antireflection film comprises:
- coating a liquid having particles dispersed in a dispersion medium and then coating a solution containing a component necessary for forming a binder to form a layer in which spaces between the particles are filled with the binder;
- and
- drying the layer.
1 more element
An optical member comprising an antireflection film formed on a substrate, wherein
- the antireflection film has a layer formed of multi-stacked particles aligned in the direction parallel to the substrate surface;
- and
- spaces between the particles in the layer are filled with the binder.
