| titleOfInvention |
Monoazo dyestuffs derived from p-sulfo-halophenyl diazo moiety and p-amino-O-alkyl coupler moiety |
| abstract |
Dyestuffs of the formula <IMAGE> wherein R1 represents a non-ionic substituent, R2 and R3 represent hydrogen, alkyl, acyl or aryl and wherein the two benzene rings A and B can in addition also be substituted by the non-ionic substituents as well as their preparation and their use for dyeing and printing fiber materials containing nitrogen, especially fiber materials consisting of polyamides, to give level orange to red dyeings with good dyestuff yields. |
