The image clarity of the electrodeposited coating of an organic coating without hydrophilic resin was inferior because a long wavelength element of 400μm or more remained on the electrodeposited coating after baking. The wettability of the organic coating was improved by adding a hydrophilic resin. It is assumed that the electrodeposited coating of the organic coating with high wettability has excellent image clarity because hydrogen gas separates quickly from the coating, reducing the size of the pores in the electrodeposited coating formed by the hydrogen gas. Using results for the size of the hydrogen gas capable of existing at the interface between the organic coating and electrodeposited coating material calculated with a static model in which the interfacial tension between the solid phase and liquid phase was in balance with the buoyancy of the gas bubbles, it was possible to explain the relative size of the pores in the electrodeposited coating by the contacl angle of the organic coating.
