An anti-fogging coating composition contains (a) an inorganic alkoxide and/or a hydroxyl group-containing polymer formed therefrom by hydrolysis and polycondensation, the inorganic alkoxide being represented by the formula (I): M(OR)n(X)a-n(I),wherein M is an inorganic element selected from the group consisting of Si, Al, Ti, Zr, Ca, Fe, V, Sn, Li, Be, B and P; R is an alkyl group; X is an alkyl group with or without functional groups or a halogen atom; a is a number representing the valence of M; and n is an integer from 1 to a; (b) a polyalkylene oxide, a weight ratio of the polyalkylene oxide to the inorganic alkoxide and/or the hydroxyl group-containing polymer being 100/1-100/150; (c) 0.5 parts by weight or less of an acid catalyst per 100 parts by weight of (a); (d) 0.01-1 part by weight of a base catalyst per 100 parts by weight of (a)+(b); (e) 100-5,000 parts by weight of an organic solvent per 100 parts by weight of (a)+(b)+(d); and (f) a stoichiometric amount or more of water for the hydrolysis of the inorganic alkoxide. |
