A new group of compounds that are useful in the dyeing of polyamides, such as nylon, silk and wool, in orange hues. The dyes have the formula:
wherein R is -H, -CH3, - CH2CH3, -C6H5, or -CH20H;
R1 is -H or R16, wherein
-SO2 lower alkyl, -SO2 phenyl, or -SO2 phenyl substituted with one or more halo, lower alkyl, or lower alkoxy groups;
R2 is -H, -lower alkyl, -lower alkoxy, or -Cl;
R3 is -H, -lower alkyl, -lower alkoxy, or -Cl;
R4 is -H, -CH3, -CH2CH3, or -
R11 is -H or - lower alkyl;
M is -H, -Li, -Na, -K, NH4, or -N(R5)4, wherein R5 is -H or
R6 is -H, -CH3, or -CH2CH3;
n is 1, 2, 3, or 4; and
OR1 is ortho or para to the azo linkage, and when OR1 is ortho to the azo linkage, a blocking group such as -lower alkyl, -lower alkoxy, or -Cl must be present para to the azo group.
