Title:
LIQUID DISPERSION OF FLUORIDE PARTICLES, COMPOSITION FOR FORMING OPTICAL FILM, AND OPTICAL FILM
Document Type and Number:
WIPO Patent Application WO/2022/249730
Kind Code:
A1
Abstract:
[Problem] To provide a liquid dispersion of fluoride particles, the dispersion having excellent dispersibility, being suitable for production of an optical film such as an anti-reflection film, and having a refractive index lower than that of magnesium fluoride, for example; a composition for forming an optical film; and an optical film. [Solution] The liquid dispersion of fluoride particles according to the present invention is characterized by comprising fluoride particles, an anionic surfactant as a dispersing agent for the fluoride particles, and an organic solvent, and is characterized in that the fluoride particles contain, in the compositional makeup thereof, at least aluminum and an alkali metal, and an alkaline-earth metal as an optional element, and are dispersed in the organic solvent.
