Abstract

"Process for obtaining monoazo dyes", characterized, because the 1-amino-2-cyano-4-nitrobenzole or the 1-amino-2,4-dinitro-6-halogenbenzole or the 1-amino-2-cyano- Diazoated 4-nitro-6-halogenobenzole is coupled with a coupling component, free of sulphonic and carbonic acid groups, of formula ** (See formula) ** where R1 signifies hydrogen, halogen, alkyl or alkoxy, R2 residue -CnH2n + 1, R3 hydrogen, -CnH2n + 1, a cyanoethyl group or a group -CH2CH2COOR, where n is a number from 1 to 5, and Ac represents the remainder Acyl of a low aliphatic carbonic acid, in position p to the group (see formula) (Machine-translation by Google Translate, not legally binding)
