The invention relates to a suspension of cerium oxide particles, of which the particles (secondary particles) have an average size of at most 200 nm, these secondary particles consisting of primary particles whose average size measured by TEM is of at most 150 nm with a standard deviation of at most 30% of the value of said average size, and for which the ratio of the average size measured by TEM to the average size measured by BET is at least 1.5. This suspension is prepared from a solution of a cerium III salt, comprising a colloidal dispersion of cerium IV, which is brought into contact, in the presence of nitrate ions and under an inert atmosphere, with a base; the medium obtained is subjected to a thermal treatment under an inert atmosphere and then acidified and washed. The suspension can be used for polishing.

Various coating compositions, including silica based compositions, methods of preparing and using such compositions, and applications of such compositions are provided herein. In one embodiment, a process for incorporating UV-protecting nanoparticles into a sol-gel matrix along with resulting compositions and uses are described. In accordance with one embodiment, the nanoparticle synthesis and coating solution may be prepared in a single vessel, eliminating the need for additional processing steps.

As one sensor layer structure for a capacitive touch panel, a layer structure in which a transparent electroconductive layer is formed on each of opposite surfaces of a single film substrate, so-called GFD structure, is used. In the structure, for sufficiently suppressing internal reflection from the transparent electroconductive layer, it is necessary to employ a technique of forming one or more refractive index adjustment (IM) layers on each of the opposite surfaces of the single film substrate. This causes a problem that production yield is likely to deteriorate, and a production cost is increased. The present invention is directed to solving such a problem and, specifically, to laminating a refractive index adjustment zone-formed pressure-sensitive adhesive layer capable of being produced easily and at low cost, to each transparent electroconductive layer of a double-sided transparent electroconductive film, so as to effectively suppress internal reflection in the resulting laminate.
