Beschreibung
Zusammenfassung:Provided are: silica-coated particles which have satisfactory dispersibility in resins and liquid materials, have functional groups capable of reacting with resins, and also has satisfactory slipperiness as well as water repellency; and a method for producing the silica-coated particles. Silica-coated particles, in which the surface of each of solid particles (A) is coated with silica (B), a part or the whole of a hydroxyl group on the surface of the silica (B) is reacted with at least one component (C) selected from an organoalkoxysilane and a hydrolysate thereof and an organosilazane, wherein the amount of the silica (B) is 0.5 to 100 parts by mass relative to 100 parts by mass of the solid particles (A).
