A polishing composition comprising an abrasive grain; a modified microfibril cellulose in which at least a part of the cellulose units has a hydroxyl group at the C6 position oxidized to a carboxyl group; and a dispersion medium, wherein each content of Na and K is 100 ppm or less relative to the solids weight.

Polishing composition

Disclosed is a silica-based composite fine particle dispersion including a silica-based composite fine particle which comprises a mother particle containing amorphous silica as a main component with a child particle containing crystalline ceria as a main component on a surface thereof. Features of the silica-based composite fine particle include a silica to ceria mass ratio of 100:11 to 316, and when subjected to X-ray diffraction, only the crystalline phase of ceria is detected, and when subjected to X-ray diffraction for measurement, the crystalline ceria has a crystallite diameter of 10 to 25 nm.

Silica-based composite fine particle dispersion and method for manufacturing same

Conductive substrate having on their surface a coating formed from a coating solution for forming a transparent conductive coating prepared by dispersion of dissolving in water and/or organic solvent such conductive particles as having (a) an average particle diameter of not more than 500 .ANG., wherein (b) an amount of particles having a particle diameter of not more than 600 .ANG. is more than 60% by weight, (c) an amount of particles having a particle diameter of not more than 100 .ANG. is more than 5% by weight and (d) an amount of particles having a particle diameter of more than 1000 .ANG. is not more than 15% by weight, and a matrix comprising a silica polymer having (A) an average degree of polymerization of 1,500-10,000, and (B) an amount of the polymer having a degree of polymerization of not more than 3,000 being not more than 50% by weight, and (C) an amount of the polymer having a degree of polymerization of more than 10,000 being not more than 20% by weight, are excellent in adhesion and surface smoothness and also excellent in durability and transparency. Display devices provided with the above-mentioned transparent conductive substrates as the display panel are excellent in resolving power, and give constantly clear and sharp images.
