PURPOSE: Provided is a siloxane-based high refractional and ultrahigh refractional coating composition using a high refractional composite oxide filler, which is excellent in adhesive ability, gloss ability, storage and work stability. CONSTITUTION: The high refractional and ultrahigh refractional coating composition comprises: 100pts.wt. of a base resin comprising 0.1-50pts.wt. of a compound selected from the group consisting of an organosilane represented by the formula 1:R1Si(OR2)4-a, hydrolysates thereof, and partial condensates thereof, such as methyl trimethoxy silane and vinyl triethoxy silane, and 10-60pts.wt. of a compound selected from the group consisting of an organosilane represented by the formula 2:R3bSi(OR4)4-b, hydrolysates thereof, and partial condensates thereof, such as 3-glycidoxy propyl trimethoxy silane; 10-130pts.wt. of a solvent; 1-100pts.wt. of a composite oxide comprising at least three selected from the group consisting of titanium oxide, antimony oxide, zirconium oxide, and tin oxide; 0.1-10pts.wt. of a compound selected from the group consisting of zirconium alkoxide, hydrolysates thereof, and partial condensates thereof; and 10-50pts.wt. of C1-C12 ketone or diketone. In the formula, R1 and R2 are independently C1-C6 alkyl, alkenyl, halogenated alkyl, allyl, or aromatic group, a and b are an integer of 0-3, R4 is C1-C6 alkyl.
