Coating composition and coated article

A coating composition comprising (A) a hydrolytic condensate of an alkoxysilane, (B) silica colloid sol, and (C) a curing catalyst as essential components,

• the alkoxysilane hydrolytic condensate (A) is obtained from hydrolytic condensation of a hydrolyzable radical-containing organosilicon compound comprising at least 10% by weight of a compound having the general formula (I):
• wherein R1 to R4 are each independently hydrogen, halogen, alkyl, alkoxy or aryl radical, R5 and R6 are each independently hydrogen, C1-C10 alkyl or C6-C10 aryl, R5 and R6 may bond together to form a C3-C13 carbocyclic or heterocyclic ring with the carbon atom to which they are attached, the carbon-containing radicals of R5 and R6 may have a C1-C5 alkyl, C2-C5 alkenyl or C1-C5 alkoxy substituted thereon, and
• Y is each independently a radical of the formula:
• wherein R10 is C2-C6 alkylene, R11 and R12 are each independently C1-C5 alkyl, and n is 0, 1 or 2.
