In order to know dyeing properties of disperse dyes for polyethylene terephtalate (PET) substrate, measurements of the solubilities of disperse dyes in octane and n-butyl alcohol solutions, and pertision coefficients from these solutions have been made. The difference between the standard chemical potential of the dye in the solution phase and the PET phase (-Δμ^0 dyeing), and also in the dye crystalline phase and solution phase (-Δμ^0 soln) has been derived. From these values, the difference between the standard chemical potential of dye crystal phase and PET phase (-Δμ^0 dyed) has been derived, and the following results have been found. 1) The higher the values of -Δμ^0 soln are, the smaller the values of -Δμ^0 dyeing are, irrespective of solvents. 2) The values of -Δμ^0 dyed +Const. are roughly constant (-1〜-2Kcal/mol), and unrelated with dyes and solvents. 3) The larger the values of inorganicity/organicity of dyes are, the larger the values of -Δμ^0 soln are in water, but the smaller they are in octane.
