The absorption isotherms of Zambesi Black D (C. I. No.27700) (I) and aniline→p-cresidine→γ-acid (II) were determined under the same condition described in part IV. (I) and (II) showed nearly equal the mean standard affinity. (4.4 kcal). (I) contains a longer conjugated chain of double bonds than (II). These results are explained by taking into account the hydration of dye.
