The present invention relates to an ultraviolet curable organic-inorganic composite resin and an ultraviolet curable organic-inorganic composite resin composition for an optical film. More particularly, the present invention relates to an ultraviolet curable organic-inorganic composite resin in which a ultraviolet curable metal oxide nano sol-silane compound-urethane acrylate triblock organic-inorganic composite resin is formed by reaction of a nano sol-silane coupling chelate compound obtained by surface modifying a metal oxide nano sol with a silane compound and an urethane acrylate prepolymer in a weight ratio of 2:8-8:2, and an ultraviolet curable organic-inorganic composite resin composition for an optical film. According to the above-described present invention, an inorganic nano sol with a high refractive index is used, the inorganic nano sol is coupled with a silane compound and chemically combined with an ultraviolet curable resin, and thus the resin has good light diffusion properties and light scattering phenomenon and is favorable for preparing a coating solution for an optical film and various displays. |
