A dispersion includes silane-bonded inorganic oxide particles having surfaces modified with a hydrolyzable silane, and a liquid dispersion medium which contains a hydrolysate of the hydrolyzable silane; the ratio of (the number of moles of silicon atoms of the hydrolysate of the hydrolyzable silane in the dispersion medium)/(the number of moles of silicon atoms of the silane bonded to the surfaces of the particles) is 0.2 to 30; and Q4 is greater than that before the surface modification with silane, wherein Q4 corresponds to the case where the number of bridging oxygen atoms between silicon atoms of the silica particles is 4/2 per one silicon atom as determined by Si-NMR observation. The inorganic oxide particles have an average diameter of 5 nm to 100 nm and are particles of silica and at least one inorganic oxide from the group of alumina, tin oxide, zirconium oxide, titanium oxide, and antimony oxide.
