• 1. The single and mixture dyeing of Benzopurpurine 4B (C. I. 23500) and Sky Blue 6B (C. I. 24410) were examined kinetically.<BR>2. The diffusion coefficient of each dye decreased with a decrease in the surface concentration. The apparent activation energy of diffusion at a constant surface concentration was evaluated.<BR>3. In mixture dyeing, the dye distributions in the substrate were considerably different from that in the single dyeing, but there was good agreement between the dye distributions experimentally determined and those theoretically calculated in terms of the thermodynamics of irreversible processes.<BR>4. The interaction between two dyes in the substrate increased with an increase in the sodium chloride concentration in the dye bath and with a decrease in the temperature.
