Abstract

The invention comprises monoazo dyes of the formula <FORM:1005646/C4-C5/1> wherein R1 is a hydrocarbon radical R2 is a hydrocarbon radical containing at least 4 carbon atoms and Hal represents halogen and the sum of the carbon atoms of R1 and R2 is at least 9 and a process for the preparation thereof characterized by coupling a diazotized aminodiphenyl ether sulphonic acid having a hydrocarbon substituent with at least 4 carbon atoms in a medium having a pH value ranging from 4 to 8 with a coupling component of the formula <FORM:1005646/C4-C5/2> wherein R1 and Hal have the meaning given above. In examples: a scarlet dye is obtained by diazotizing 41-tert-amyl-2-aminodiphenyl ether-4-sulphonic acid and coupling with 2-chloroacetyl - isoamylamino - 8 - hydroxy naphthalene-6-sulphonic acid (1) and a similar product is prepared in which the isoamyl radical is replaced by benzyl (2). Additional examples are furnished and further diazo and coupling components are listed. The dyes are particularly suitable for dyeing wool.
