Abstract
The present invention relates to a cationic electrodeposition coating composition comprising silica particles having pore volume of 0.44 to 1.8 ml/g and average particle size of no more than 10 μm, the composition showing square root of diffusion coefficient (εTc) of no less than 2.5 upon diffusing a solution onto a coating film therewith; a cationic electrodeposition coating composition comprising silica particles having pore volume of 0.44 to 1.8 ml/g and average particle size of no more than 10 μm, wherein the composition shows minimum deposition pH of 11.90 to 12.00 during electrodeposition coating, and film resistance of 1,000 to 1,500 kΩ.cm2 at film thickness of 15 μm and applied voltage of 240V; and an article coated with such cationic electrodeposition coating composition. Therefore, the present invention can also provide a coating film formed with the cationic electrodeposition coating composition which can ensure higher corrosion resistance and higher throwing power in addition to other excellent coating properties, even if the resulting coating has extremely thin film thickness (e.g., about 7 μm).
