摘要： A subject for the invention is to form a coating film which has high transparency and excellent adhesion to organic base materials and retains long-lasting excellent effects concerning hydrophilicity, antifogging properties, droplet repellency, and antifouling properties. The invention relates to an inorganic coating composition capable of forming a hydrophilic coating film on an organic base material, the organic coating composition comprising alumina particles having an aggregate diameter in a dispersion medium of 20-400 nm and either a silicic acid oligomer or a colloidal silica, a surfactant, a water-miscible organic solvent which is capable of swelling or dissolving the organic base material and has a boiling point of 120° C. or higher at an atmospheric pressure of 0.1 MPa, and water, the content of water in the inorganic coating composition being 400-1,700 parts by weight per 100 parts by weight of all solid components of the composition, and the inorganic coating composition having a concentration of the organic solvent of 1-10% by weight and a solid concentration of 0.1-20% by weight.
