Title: Electrodeposition coating method
Inventor: NARUSE KAZUHIDE
IPC: C25D13/22
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To prevent a difference in film thickness at a draft part from being formed when the electrodeposition coating of the lower coating position is carried out in a half submerged state. SOLUTION: The electrodeposition coating is carried out while atomizing a coating liquid contng. an electrodeposition coating material on the draft part 11 at the time of the electrodeposition coating in a half submerged state. The concentration of a current does not occur and coating ions are surely electrodeposited at the draft part 11, thus the coating film is prevented from being broken. Further, foaming due to atomization occurs and a drop in voltage of the coating liquid in a thin layer occurs at the draft part 11, thereby generating a gradient in the thickness of the coated film, too, and thus a difference in the thickness of the coated film is reduced.

Then an information embedding part 14 embeds the watermark information in the center part, so that a series of the processes ends. The watermark information embedded by the information embedding part 14 is read by inputting a distributed image and the original image by a read means.
