1-Cyclohexylamino-, 1-bromo-4-cyclohexylamino-, 1-amino-4-cyclohexylamino-and 1, 4-his (cyclohexylamino)-anthraquinones were synthesized from 1-chloroanthraquinone. Their visible absorption spectra in solution were measured and their dyeing properties on synthetic fibers evaluated. When compared with the corresponding amino-, methylamino-, isopropylamino-, and anilin oanalogs, etc., cyclohexylaminoanthraquinones showed the absorption peaks at longer wavelength. It thus seems that cyclohexylamino group is most effective in shifting the absorption maximum. In general, those visible absorption peaks appeared at longer wavelengths in nonpolar solvent such as benzene than in polar solvent such as ethanol. Their dyeing properties on synthetic fibers were of 2-3 grade, except that of 1, 4-his (cyclohexylamino) anthraquinone which is of 1 grade.
