Document Type and Number:
Japanese Patent JP5194465
Kind Code:
B2
Abstract:
A coated steel sheet that has excellent bending workability, press formability, film adhesiveness after processing, solvent resistance, chemical resistance, stain resistance, weather resistance, electrical conductivity, and corrosion resistance, good surface appearance, and sufficient film hardness is provided. The coated steel sheet is produced by successively forming a galvanized layer and a chemical conversion coating free from chromium on both faces of a steel sheet, and forming a monolayer film on the chemical conversion coating at one face of the steel sheet. The monolayer film contains a polyester resin cured with a cross-linker and resin particles. The resin particles have an average particle size in the range of 3 to 40 µm, a glass transition temperature in the range of 70°C to 200°C, and hardness higher than that of the polyester resin.
