Abstract:
1. A coated steel sheet coated with a composite coat, wherein said composite coat is a coat formed by compounding ethylene-unsaturated carboxylic acid copolymerization resin particles (A) having an average particle diameter of 20 to 100 nm and a silanol group and/or an alkoxysilyl group, which is obtained by reacting a water dispersion of ethylene-unsaturated carboxylic acid copolymerization resin particles with an epoxy group-containing silane compound, silicon oxide particles (B) having an average particle diameter of 5 to 50 nm, an organic titanium compound (C), a phosphate compound, and at least one compound (D) selected from the group consisting of a thiocarbonyl compound, a niobium oxide and a guanidine compound, wherein an amount of a coat of said composite coat is 0.5 to 3 g/m
