    摘要： [Problem]
    The invention provides titanium oxide fine particles which are excellent in transparency and are less photocatalytically active while maintaining a high refractive index, a dispersion of such fine particles, and a method for producing such a dispersion.
    [Solution]
    A method for producing a dispersion of iron-containing rutile titanium oxide fine particles including a step (1) of neutralizing an aqueous metal mineral acid salt solution containing Ti and Fe in Fe 2 O 3 /(TiO 2 + Fe 2 O 3 ) = 0.001 to 0.010 to form an iron-containing hydrous titanic acid; a step (2) of adding an aqueous hydrogen peroxide solution to form an aqueous solution of iron-containing peroxotitanic acid having an average particle size of 15 to 50 nm; a step (3) of adding a tin compound so as to satisfy TiO 2 /SnO 2 = 6 to 16; a step (4) of adding a sol of silica-based fine particles which contain Si and a metal element M in SiO 2 /MO x/2 = 99.9/0.1 to 80/20, the addition being made so as to satisfy SiO 2 /(oxides of the other elements) = 0.08 to 0.22; and a step (5) of hydrothermally treating the solution obtained in the step (4).

    摘要： An object of the invention is to provide surface-treated fine particles which, when added to coatings for the production of films, exhibit excellent reactivity with respect to organosilicon compounds and resins that are matrix components of the coating films, and thereby allow the films to exhibit excellent performance. Oligomer-modified fine particles include inorganic oxide fine particles having a surface modified with an oligomer, the oligomer being derived from a metal alkoxide represented by Formula (1): R n M 1 (OR') z-n (1) wherein M 1 : one or more elements selected from Si, Ti, Zr and Al; R and R': one or more groups selected from alkyl groups of 1 to 8 carbon atoms, aryl groups and vinyl groups; n: an integer of from 0 to (z - 2); and z: the valence of M 1 . The oligomer has a polymerization degree of 3 or more. The oligomer has a weight average molecular weight in the range of 1000 to 10000.
