要約
(EN)
The purpose of the present invention is to make the surface of a film, which is made from a polysiloxane-type organic-inorganic complex and of which the surface has higher hardness than that in the inside thereof, further inorganic. An organic-inorganic composite thin film according to the present invention has a layer comprising (a) a condensation product of an organosilicon compound represented by formula (I): RnSiX4-n (wherein R's independently represent an organic group in which Si is bound to a carbon atom directly; X's independently represent a hydroxy group or a hydrolysable group; n represents 1 or 2; R's may be the same as or different from each other when n is 2; and X's may be the same as or different from each other when (4-n) is 2 or more) and (b) an organic polymeric compound, wherein a layer produced by condensing the condensation product of the organosilicon compound represented by formula (I) is formed on the surface of the film, the concentration of carbon atoms at the depth of 10 nm from the surface is smaller by 20% or more than the concentration of carbon atoms at the depth of 100 nm from the surface, and the O/Si elemental ratio at the depth of 2 nm from the surface of the film is 1.8 to 2.5.
