Abstract
A liquid composition that can provide a film having excellent antifogging performance and weather resistance. The liquid composition contains nanocomposite particles. The nanocomposite particles contain metal particles and a perfluorocarbon sulfonic acid resin or a sulfonic acid salt resin thereof. The perfluorocarbon sulfonic acid resin has an equivalent weight of 550 to 800. The nanocomposite particles have an average particle size of 15 to 100 nm.
Claims14
A liquid composition comprising nanocomposite particles,
- the nanocomposite particles containing metal particles and a sulfonic acid salt resin of a perfluorocarbon sulfonic acid resin,
- the sulfonic acid salt resin being a salt obtained by replacing a hydrogen ion of a sulfonic acid group by a cation,
- the cation being at least one selected from the group consisting of Na+ and Li+,
- the perfluorocarbon sulfonic acid resin having an equivalent weight of 550 to 800, and
