PROBLEM TO BE SOLVED: To provide a cationic electrodeposition coating composition that can ensure high rust prevention and high throwing power even with a very thin film thickness (for example, a film thickness of about 7 μm), and is excellent in other coating film performance. . SOLUTION: It contains silica particles having an average particle size of 10 μm or less with a pore volume of 0.44 to 1.8 ml / g, a minimum precipitation pH in electrodeposition coating of 11.90 to 12.00, and 15 μm 240 V. A cationic electrodeposition coating composition having a coating film resistance of 1,000 to 1,500 kΩ · cm and a coated product obtained therefrom. [Selection] Figure 1 |
