An object of the present invention is to provide an inorganic organic hybrid material capable of realizing an optical material having the opposite function of flexibility and high refractive index, and having a low yellowness and high transparency. This invention contains an inorganic component and an organic component, the content rate of an inorganic component is 20-80 mass%, the refractive index is 1.60 or more, using this inorganic organic hybrid material, thickness 1000 micrometers, width 5mm, length 70mm It is related with the inorganic organic hybrid material which does not produce a crack when the monocle-shaped test piece of this product was manufactured, and it wound at 180 degreeC on the cylindrical metal rod of 10 mm in diameter at 25 degreeC. Moreover, as a composition containing a radiation curable monomer, the inorganic particle whose size is 1-10 nm of crystallite diameter computed from the half value width of the crystalline peak by X-ray diffraction method, and a sulfur containing organic compound, It is related with the inorganic organic composite composition containing a monofunctional radiation curable monomer and a polyfunctional radiation curable monomer, and whose content of a sulfur containing organic compound is 1.5-10 mass% in conversion of a sulfur atom. |
