The present invention relates to dyes of general formula (I), mixtures of these with further dyes and to the preparation and use thereof:n n n [Formula I]n n n n n n n n [In the meal,n n n X and Y = H, Br or Cl, but not simultaneously H,n n n R = F, Cl, Br, COOR 1 or CF 3 ,n n n R '= H or F,n n n R 1 = C 1 -C 6 -alkyl,n n n One of the W 1 and W 2 groups = hydroxy and the other is nitro and Y is always ortho to the hydroxy group;n n n Provided that R is Cl bonded to the phenyl ring in the ortho position relative to the NH group and W 1 = nitro, W 2 = hydroxy, Y = H, X = Cl and R are bonded to the phenyl ring in the meta position relative to the NH group Excluded compounds of Br]. |
