1. A process for mass-colouring synthetic polyamide, in which the synthetic polyamide containing the dyes or dye mixtures is melted and the melt is spun or shaped using known methods, which comprises using as dye either mixtures of the 1 : 2 chromium complex of a monoazo dye of the formula I see diagramm : EP0138749,P9,F1 in which R**1 and R**3 , independently of each other, are each -H or -Cl, and R**2 is H, C1 -C4 alkyl and/or Cl, and the 1 : 2 chromium complex of a monoazo dye of the formula II see diagramm : EP0138749,P9,F2 in which R**4 is -H or -Cl, and R**5 is -H, -Cl, -CH3 , C1 -C2 -alkylsulfonyl or -SO2 NH2 , or a mixed 1 : 2 chromium complex of a monoazo dye each of the formula I and the formula II in which R**1 , R**2 , R**3 , R**4 and R**5 are as defined above. |
