Abstract:
1. An article with an organic-inorganic composite film, the article comprising a substrate and an organic-inorganic composite film that is formed on a surface of the substrate and comprises an organic material and an inorganic oxide, wherein the organic-inorganic composite film contains a network structure of silica in a form of siloxane polymer as the inorganic oxide, the organic-inorganic composite film contains the silica as its main component, the organic-inorganic composite film contains a hydrophilic organic polymer as the organic material in the network structure of silica, the organic-inorganic composite film is a single-layer film and an outermost layer, the organic-inorganic composite film is formed directly on a substrate, wherein the substrate is a glass sheet, the organic-inorganic composite film has a thickness of more than 250 nm and no more than 5 μm, and the organic-inorganic composite film does not separate from the substrate after the Taber abrasion test prescribed in Japanese Industrial Standards R 3212 that is carried out with respect to a surface of the organic-inorganic composite film, the Taber abrasion test being carried out at a rotation number of 1000 with a load of 500 g being applied.
