    摘要： Hollow silica-based particles having cavities inside the outer shell having a low refractive index. The method of producing the silica-based particles comprises the following steps (a) and (b): (a) a step in which, when an aqueous silicate solution and/or an acidic silicic acid solution and an aqueous solution of an alkali-soluble inorganic compound are simultaneously added in an alkali aqueous solution to prepare a dispersion liquid of composite oxide particles, an electrolytic salt is added at the molar ratio of a mole number of the electrolytic salt (ME) versus that of SiO2 (MS) [(ME)/(MS)] in the range from 0.1 to 10, and (b) a step of furthermore adding an electrolytic salt, if necessary, to the dispersion liquid of composite oxide particles and then removing at least a portion of elements constituting the composite oxide other than silicon by adding an acid to prepare a dispersion liquid of silica-based particles.

Also provided is a display device having a front panel constituted of a substrate with such a transparent film applied thereto. The transparent film-forming coating liquid comprises inorganic oxide particle groups, in each of which 2 to 10 inorganic oxide particles on an average are linked in the form of a chain, and a polar solvent. In the transparent film-forming coating liquid, the inorganic oxide particles have an average particle diameter of 4 to 200 nm. The inorganic oxide particles are silica particles, and the silica particles are porous particles and/or hollow particles each having a cavity inside.

    摘要： An anti-glare film comprises an anti-glare layer, and a low-refraction-index layer formed on at least one surface thereof and comprising a low-refraction-index resin and a hollow silica particle. The film has an internal haze of 0 to 1%, a haze of 5 to 6.5%, a transmitted image clarity of 20 to 30%, and a reflected light of the film has a* of 0.5 to 1.3 and b* of −2.3 to −0.5. The particle may have a mean particle diameter of about 50 to 70 nm and a refraction index of about 1.2 to 1.25. The film may have an uneven surface, and the average inclination angle of the surface may be about 0.7 to 1°. The anti-glare layer may comprise plural polymers and have a domain formed by a phase separation, and a difference in refraction index between the polymers may be about 0 to 0.04.

    摘要： Provided is a process for producing electrode catalyst fine particles capable of affording formed catalysts such as membranes excellent in uniformity and strength and also employable as catalyst to exhibit high catalytic activity over long periods because fine metal particles are highly distributed on carriers to make particle growth or the like less likely to occur. Electrode catalyst fine particles comprise fine particles which have an average particle diameter of 10 nm to 10 μm and in which fine metal particles are supported on carrier particles, wherein a potential difference (absolute value of (II) minus (I)) between a flow potential (I) of a water dispersion of the fine metal particles at 1 wt % concentration and a pH of 3 to 8 and a flow potential (II) of a water dispersion of the carrier particles at 1 wt % concentration and a pH of 4 to 10, is in the range of 10 to 3000 mV.
