Abstract:
An antifogging article excellent in both an antifogging property and abrasion resistance and a manufacturing method thereof are provided. The antifogging article includes: a substrate; a water-absorbing resin layer disposed on the substrate; and an overcoat layer disposed on the water-absorbing resin layer and including: a hydrolyzed condensate of an alkoxysilane compound; and silica particles, wherein a film thickness of the overcoat layer is 20 to 350 nm and the overcoat layer is formed from an overcoat composition containing 90 to 45 parts by mass of the alkoxysilane compound and 10 to 55 parts by mass of the silica particles relative to total 100 parts by mass of the alkoxysilane compound and the silica particles.
Abstract:
To provide a process for producing a glass substrate provided with an inorganic fine particle-containing silicon oxide film, wherein inorganic fine particles having a desired particle size may be used depending on intended optical properties, and the range of selection of the inorganic fine particles is wide.A process for producing a glass substrate provided with an inorganic fine particle-containing silicon oxide film, which comprises applying a coating liquid containing inorganic fine particles 14, a hydrolysate of an alkoxysilane, and one of or both water and a (poly)ethylene glycol, to a glass substrate 10 to form an inorganic fine particle-containing silicon oxide film 12; or which comprises forming molten glass into a glass ribbon, annealing the glass ribbon, and at the time of cutting the glass ribbon to obtain a glass substrate, applying a coating liquid containing inorganic fine particles, a hydrolysate of an alkoxysilane, and one of or both water and a (poly)ethylene glycol, to the glass ribbon to form an inorganic fine particle-containing silicon oxide film.
Abstract:
An antifogging article having an antifogging film excellent in antifogging property and in durability, an article for transportation apparatus provided with the antifogging article, and a base layer forming composition with sufficiently long pot life used for obtaining the antifogging article are provided. An antifogging article has a substrate, and an antifogging film on the substrate having a base layer made of a base material with low water absorbing property, and a water absorbing layer made of a water absorbing material having a water absorbing property higher than that of the base material, and the base material is obtained by using a composition containing (A) a raw material component of a first cured resin, (B) a silane-based coupling agent having a functional group other than an amino group having reactivity with the (A) component and a hydrolyzable group, and (C) tetraalkoxysilane and/or a polymer thereof in a prescribed ratio.
