PROBLEM TO BE SOLVED: To provide a cationic electrodeposition coating composition that excels in corrosion resistance, especially even in the corrosion resistance for an electrodeposition coating film in which a formed coating film is a thin film of 15 μm of a dry film thickness, and that excels in coating stability without using a harmful substance such as a lead compound and a chromium compound.SOLUTION: A cationic electrodeposition coating composition includes: an organic binder containing a cationic resin (a1); and a silane condensation reaction product of an aminosilane (b1) and a multi silyl functional silane (b2). In addition, a method for forming a coating film and a coated article using the cationic electrodeposition coating composition are disclosed. |
