Sulfonylaminophenalenones and acylaminophenalenones were synthesized by the acylation of 2-amino phenalenone with aromatic sulfonyl chlorides and aromatic or aliphatic dicarboxylic chlorides. The visible absorption spectra of these compounds were measured. The wave number (ν) corresponding to the absorption maxima λ<SUB>max</SUB> of 2- (<I>p</I>-substituted phenylsulfonyl) amino-1-phenalenones were linearly related to the Hammetts substituent constants (σ) (ρ+0.038). Their dyeing properties as disperse dye on polyester fiber were examined. Dyeabilities of the 2-sulfonylamino-1-phenalenones were good, but those of the acylaminophenalenones were poor. The colors of dyed cloth were yellow except for the 2, 2-phthaloylaminodi (1-phenalenone) (pale reddish yellow). Most of the dyed fiber showed good fastness to light and to sublimation, especially sublimation fastness of the acylaminophenalenones were excellent.
