Abstract

The present invention discloses substituted phenyl di and trisazo dyes free of reactive groups having two or three sulfonic acid groups, of the general formula: ##STR1## wherein D.sup.1 is ##STR2## Z is hydrogen or D.sup.4 --N.dbd.N--; D.sup.2 is phenyl substituted by hydroxyl, hydroxysulfonyl, chlorine or nitro, or is naphthyl substituted by hydroxy, hydroxysulfonyl or nitro, X, independently of one another, are hydroxyl or amino, D.sup.3 is phenyl which is substituted by hydroxysulfonyl, chlorine, bromine, methyl, methoxy, ethoxy, nitro, phenylamino, sulfophenylamino or nitrosulfophenylamino, or is naphthyl which is substituted by hydroxysulfonyl; D.sup.4 is phenyl which is unsubstituted or substituted by methyl, ethyl, methoxy, ethoxy, chlorine, bromine, nitro, sulfamoyl or hydroxysulfonyl, or is naphthyl which is substituted by hydroxysulfonyl; and R.sup.2 is methyl, ethyl or allyl; the rings B and E may additionally be substituted by methyl, ethyl, methoxy, ethoxy, chlorine, bromine or hydroxysulfonyl, with the proviso that D.sup.2 has a hydroxyl group ortho to the azo bond; or the iron, manganese, cobalt, chromium, nickel or copper complexes of this dye. These compounds, part…
