Abstract

Improvements introduced in the object of the main patent number 368,836, granted on September 7, 1970, by: Procedure for the production of water-insoluble monoazo dyes, which in one of the possible tautomeric forms are represented by the formula: ** (See formula) ** wherein Z2 is a hydrogen atom or a lower alkyl radical; R1 is a hydrogen atom or an alkyl, aryl, cycloalkyl or aralkyl radical; R2 is an alkyl radical containing 5 or more carbon atoms; and benzene ring B can be further substituted by nitro, cyano, alkyl, alkoxy, chlorine, bromine, phenyl or phenoxy; characterized in that they comprise diazotizing an amine of the formula: ** (See formula) ** and coupling the resulting diazo compound with a coupling component of the formula: ** (See formula) ** where R1, R2, Z2 and B are defined as above.
