Abstract: An article with a silica-based film that contains an organic material and has excellent mechanical strength. This article includes a substrate and an organic-inorganic composite film that is formed on the surface of the substrate. The organic-inorganic composite film contains silica as its main component. A value of (0.19A+0.03) or lower (A denotes the film thickness [?m]) is obtained through X-ray diffraction analysis on the organic-inorganic composite film, with the X-ray incident angle being fixed at 1° with respect to the surface of the organic-inorganic composite film, when the intensity of a peak at a diffraction angle of 3° to 10° is standardized using the intensity of a halo pattern peak at a diffraction angle of 20° to 30°. A value of 0.

Abstract: An article with an organic-inorganic composite film that contains silica as its main component and does not separate from the substrate after the Taber abrasion test prescribed in Japanese Industrial Standards (JIS) R 3212. This composite film is formed of a coating solution containing a hydrophilic organic polymer by a sol-gel process. In this solution, for example, the amount of silicon alkoxide exceeds 3 mass % in terms of a SiO2 concentration. When the coating solution contains a phosphorus source, the molality of protons is 0.0001 to 0.2 mol/kg while the number of moles of water is at least four times the total number of moles of silicon atoms contained in the silicon alkoxide. This sol-gel process allows a film with excellent mechanical strength to be obtained even when the substrate is not heated up to a temperature exceeding 400° C. and the film thickness exceeds 250 nm.
