Abstract
Procedure for preparing azo dyes, free of carboxylic acid and sulfonic acid groups, and having the formula: ** (Formula) ** in which D is the residue of a carbocyclic aromatic amine DNH2, containing D as substituent at least one group chosen from nitro, cyano, -SO2NR6R7 and -SO2R8 where R6 and R7 are hydrogen, an optionally substituted alkyl, aryl or aralkyl group and R8 is an optionally substituted alkyl or aralkyl group, provided that when D contains a non-nitro substituent contains more than one chlorine substituent, R1 is hydrogen, lower alkyl or lower alkoxy, R2 is hydrogen or alternatively R1 and R2 taken together with the two carbon atoms of the benzene ring to which they are attached form a ring fused to the benzene ring, the ring of which fused may contain heteroatoms, R3 is a halogen atom, Y is an alkylene radical, R4 is hydrogen or an alkyl, alkenyl, cycloalkyl or aralkyl radical optionally substituted, R5 is hydrogen or an optionally substituted alkyl or alkenyl radical.
