Title:
MULTILAYER FILM, OPTICAL MEMBER INCLUDING MULTILAYER FILM, AND METHOD FOR PRODUCING MULTILAYER FILM
Document Type and Number:
WIPO Patent Application WO/2024/053125
Kind Code:
A1
Abstract:
Provided are: a multilayer film which, even when including a surface low-refractive-index layer having a film thickness increased to or above a given value in order to reduce light reflectance, sufficiently exhibits the self-cleaning function of the surface due to photocatalytic reaction and can retain hydrophilicity in the dark for a long period; an optical member including the multilayer film; and a method for producing the multilayer film. This multilayer film is a multilayer film provided to a glass, a resin, etc. and comprises: a layer including a specific cerium oxide; and, disposed directly thereon or disposed thereover on another layer, a layer including a specific silicon oxide or a layer including a specific magnesium fluoride. The optical member includes the multilayer film, and the method is for producing the multilayer film.
