As a part of consecutive research titled on the heading of this paper, a study on selecting of suitable oil-colors, which will be absorbed on the unsealed area of anodized aluminium plate, was carried out by the evaluation of critical surface tensions of dyed surfaces. As the results, it was found that the surface dyed by Neozapon blue, Neozapon yellow or Oil red showed the critical surface tension of 26dyn/cm to 30dyn/cm, and any of them were ink-receptive. It was ascertained that the oil-colors mentioned above had no affinity to sealed area of anodized aluminium plate. Further, the stabilization energy by the nondispersion forces on undyed surfaces were evaluated by the measurments of contact angles in three-phase system of water-hydrocarbon-sealed surface of anodized aluminium plate. It was consequently obtained that the stabilization energy of them were 7dyn/cm to 8dyn/cm.
