p-Aminoazobenze ne, 4-amino-1, 1-azonaphthalene, 1-amino-4-cyclohexyl-aminoanthraquinone, and 1-amino-4-hydroxyanthraquinone, respectively, is made to react with cyanuric chloride to give a dichloro-s-triazine type pigment, (F=residual group of the pigment). Reaction of this with monoethanolamine, diethanolamine, N, N-diethylethyl-enediamine, and ethylenimine, respectively yielded dyes with general formula, where R=H or R; R=-CH2CHZOH, -CH2CH2N(C2H5)2 or The dyeing properties of these pigments with substituent groups, such as -N(CH2CH2OH)2 and -NHCH2CH2OH were considerably selective, and Nylon. Vinylon and acetate fibers were dyed well, but cotton, rayon. Tetron and acrylonitrile type fibers were not dyed by these pigments. The basic pigments having a substituent group, -NHCH2CH2N(C2H5)2, showed the characteristics of basic pigment and had less selective property, they dye silk well, and the dyeing properties to rayon, wool and acrylonitrile type fibers was increased, while that of to Nylon, Vinylon and acetate fibers decreased. The quarternary salt also showed the same dyeing property. The products containing ethyle-nimino group as substituent had a charcteristic of reactive or polymerizable pigment, they were fixed on cotton by a mere heating at 110-30°c without condensation agent such as alkali, and the dyed materials were fast against the extraction test with pyridine.
