The visible spectra of 1 -substitutedbenzoylaminoanthraquinones were measured in some solvents ; benzene, ethanol and acetone ; to discuss solvent effect on spectra. Taking the data of o-dichlorobenzene solution into consideration, following relations are found. 1) Independent of polarity of solvents, the maximal absorption wavenumbers (ν) are linearly related to Brown-Okamoto's σ^+ values. 2) The νmax of 1-benzoylaminoanthraquinone in the solution increases linearly with the value of dielectric constant of solvent. 3) Applying the Yukawa-Tsuno's Equation to the νmaxS of 1-acylaminoanthraquinones in the solution, the contribution (r) of resonance effect of substiluent increases in proportion to the value of dielectric constant of solvent. 4) Correlation between ρ values and the values of dielectric constant of solvents is under investigation.
