The relationship between the ζ potential and the codeposition of hydrophobic CF (S) and hydrophilic TiO<sub>2</sub> (A) particles have been investigated. The bath to which anionic and cationic surfactants were added in distilled water, acid copper sulfate baths, and Watts baths. The maximum ζ potential of CF (S) particles was +44 7mV and that the maximum potential of TiO<sub>2</sub> (A) particies was +13 4mV in distilled water due to the adsorbance of cationic surfactant on particies. The minimum ζ potential of CF (S) particles was -510mV and that the minimum potential of TiO<sub>2</sub> (A) particle was -150mV in deposition baths due to the adsorbance of anionic surfactant on particles. A codeposited coating was obtained in cases where the cationic surfactant was adsorbed do CF (S) particles. Such a codeposited coating was not obtained, however, in cases where the anionic surfactant was adsorbed on CF (S) particles. We further found that a codeposited coating was obtained in cases where both of the above surfactants were adsorbed on TiO<sub>2</sub> (A) particles, the amount of codeposited TiO<sub>2</sub> (A) particles obtained, however, was found to be less than that of the cationic surfactant adsorbed on CF (S) particles. In conclusion, we found that the behavior of codeposition turned out to be markedly different depending on the character of the dispersed particles involved.
