Abstract: A method for manufacturing organic-inorganic hybrid coating solution is provided to ensure excellent hardness of a coating film in hard coating to a transparent plastic and to improve adhesive force between a coating layer and material. A method for manufacturing organic-inorganic hybrid coating solution comprises the steps of mixing colloidal silica, alcohol and water in a weight ratio of 0.2-3:0.2-3:0.2-3; controlling pH to become weakly acidic by adding an acid while stirring the mixture for 1 hour; adding glycidoxypropyl trimethoxysilane to the pH-controlled solution and stirring the solution at 30 °C for 24 hours; and adding ethylene diamine to the stirred solution to become the molar ratio of 1:1-3.
