Surface character of phthalocyanine blue pigments cotreated with acidic and basic derivatives has been studied in the respect of electrical phenomena in two kinds of different alkyd resin solutions. In short-oil-modified alkyd solution, surface potential increased proportionally as the basic treatment ratio increased; while in long-oil-modified alkyd solution, the increase of the surface potential was not proportional. In order to clarify the effect of the cotreatment on the surface potential, the elctrical conductivity of the dispersion in each resin solution was measured. The electrical conductivity increased as the basic treatment ratio increased, but the increasing rate was not proportional. The study of electrical phenomena suggested that acid and basic groups on the surface of cotreated pigment affect each other to be activated, and the treated surface interact with the resins.
