PURPOSE:To obtain a coating compsn. which gives a coating film having improved scratch resistance, surface hardness, flexibility, transparency, antistatic properties, etc., by incorporating a specific organosilicon compd. or its hydrolyzate and a composite colloidal sol comprising tatinium and antimony oxides into the compsn. CONSTITUTION:A coating compsn. contains an organosilicon compd. of formula I [wherein R<1> is a 4-14C org. group having a functional group or a double bond; R<2> is a 1-6C (halogenated) hydrocarbon group; R<3> is 1-4C alkyl, alkoxyalkyl, or acyl; and a is 0 or 1 and b is 0-2 provided a+b is 1 or 2] or its hydrolyzate, a composite colloidal sol comprising 100 pts.wt. titanium oxide and 2-100 pts.wt. antimony oxide, and, if necessary, a metal complex of formula II (wherein M is Zn, Mn, Mg, Fe, Cu, Co, Ca, Bi, or Al; and c is 1 or 2). |
