PURPOSE: An organic/inorganic composite coating composition is provided to have excellent coating membrane with only one coating, to have excellent pigment dispersity, and to obtain 3H or more in surface hardness even with a coating thickness of 8 microns or less. CONSTITUTION: An organic/inorganic composite coating composition comprises 20-50 weight% of an inorganic resin synthesized by reacting inorganic colloidal sol and silane, 10-20 weight% of an urethane-based polymer resin synthesized by reacting a bifunctional or trifunctional isocyanate-based compound with a molecular weight of 200-3000, 10-20 weight% of a pigment dispersion for expressing color, and 10-50 weight% of an organic solvent, and additionally comprises 0.01-1.0 weight% of a perfluoroalkylsilane-based fluorine compound for obtaining anti-fouling performance to improve a leveling of a coating film. |
