Magnetic image on an anodized Al plate was made by the electroplanting technique utilized area selective sealing technique for anodized Al. Fe cannot be deposited directly on the anodized Al plate with d. c. electroplating, but was able to be deposited after the deposition of Cu. Since Cu can be deposited on the sealed area of the anodized Al plate. Fe could be selectively deposited onto the Cu coated area. The resolution of the image with the d. c. electroplating was not so good. The B-H curve of Fe showed ferromagnetism. With a. c. electroplating of anodized Al plate using the metal sulfate aqueous solution, not only Fe but also Co or Ni were deposited uniformly on the unsealed area with one operation. The resolution of the image with the a. c. electroplating was equal to the dyed image of the unsealed area. B-H curves of these metals deposited on the alminium plates were showed ferromagnetism. Especially, B-H curve of Fe showed hard magnetism. The maximum He (coercive force) was obtained by the use of mixture solution of Fe and Co sulfate.
