PURPOSE: Provided are a coating composition for anti-fogging, which has a ultraviolet screening effect, an improved hardness of a coated surface, and excellent antistatic property, and coated products obtained from the composition. CONSTITUTION: The coating composition comprises 0.01-80wt% of a silane compound(formula 1:£((R1O)3Si-R2-NHCOOR3-)2NR6(R4-Q-R5)|+ X-), 0-30wt% of a metal oxide(formula 2:RcdM(ORb)a), 0-10wt% of a titanium compound, 0-20wt% of an organic stabilizer, and 20-99.9wt% of distilled water in the presence of an acid or base catalyst such as acetic acid, formic acid, triethylamine, pyridine, and etc. And the coated product is produced by coating a support with the composition, wherein the support is selected from the group consisting of fabrics, an aluminium foil, a polyolefin film, polyurethane film, and etc. In the formula, R1 is methyl, ethyl, propyl, isopropyl, or hydrogen, R2, R4, and R6 are less than C20 straight or branched alkyl or phenyl, R3 is less than C50 with ethylene oxide, propylene oxide, or isopropylene oxide, Q is -OCOR5, CH2, R5 is C8-C18 straight or branched alkyl, X is an anion selected from halogen or CH3SO4, M is Si, Ti, Al, Zr, etc., a is an integer of less than 4, b is C0-C4 straight or branched alkyl or hydrogen, Rc is less than C20 straight or branched alkyl, and d is an integer of 0-3. |
