A method of producing silica-based particles includes, when a dispersion liquid of composite oxide particles is prepared by simultaneously adding an aqueous silicate solution and/or an acidic silicic acid solution and an aqueous solution of an alkali-soluble inorganic compound in an alkali aqueous solution or in an alkali aqueous solution with seed particles dispersed therein, if required, the aqueous silicate solution and/or the acidic silicic acid solution and the aqueous solution of alkali-soluble inorganic compound are added so that the molar ratio of MO

Provided are silica-based fine particle dispersion sols, processes for producing the sols, coating compositions containing the dispersion sol, curable coating films obtained from the coating composition, and substrates having the coating film. The process including (1) mixing an aqueous aluminate solution to an alkaline silica sol which contains water-dispersible silica fine particles in a given ratio; (2) heating the mixture liquid obtained in step (1) to 60 to 200 C. and stirring the mixture liquid at the temperature for 0.5 to 20 hours; and (3) contacting the mixture liquid obtained in step (2) with a cation exchange resin to remove by ion exchange alkali metal ions contained in the mixture liquid and thereby controlling the pH of the mixture liquid to be in the range of 3.0 to 6.0.
