New dyes developed for use in the process are e.g. of formulae: (I (where X = -SO2NHCOR1 or -CONHSO2R1, R1 = lower alkyl (i.e. 1-4C) or aryl, R2 and R3 = H, Cl, Br alkyl, NO2,CN,SO2R (R = alkyl) or SO2NH2, R4 and R5 = H, Hal, -OCH2CH2OH, alkyl, 1-4C alkoxy or acylamino, R6 and R7 = H, alkyl, C2H4OH,C2H4O acyl, C2H4CN or C2H4COOR) and various modifications thereof (e.g. with -X attached to other benzene ring or to a subst. on that ring). The dyes overcome the problems of obtaining uniform colorations on polyamide fibres that arise from chemical, physical and structural irregularities in the fibres. Good fastness is achieved without the need to use tanning agents. The colourants can also be used on cellulose esters and ethers (e.g. secondary acetate and triacetate) and polyesters. The dyes are applied from aq. or organic-solvent solns. Pref. organic solvents have b.p. 40-170 degrees C, esp. pref. are C2Cl4, C2HCl3 and 1,1,1-trichloroethane.
