Asymmetrical polyazo chromium complex dyes comprising resorcinol as a coupling component

A chromium complex dye of the formula ##STR120## in which A is benzene or naphthalene which carries a hydroxyl or carboxyl group in o-position relative to the azo group, and which is unsubstituted or substituted by low molecular weight alkyl or alkoxy, halogen, notro, cyano, sulfo, carboxyl, phosphono, alkylsulfonyl, sulfamides or acylamino selected from the group consisting of low molecular weight alkanoylamino, low molecular weight alkylsulfonylamino, low molecular weight alkoxycarbonylamino, sulfonylamino, aroylamino and arylsulfonylamino,

• B is benzene or naphthalene which carries a hydroxyl or carboxyl group in o-position relative to the azo group, and which is unsubstituted or substituted by the substituents mentioned for A,
• C is a coupling component which contains the group X in o- or .alpha.-position relative to the azo group and apart from the group X there is no hydroxyl group or unsubstituted amino group if C is a phenol coupling component as defined below, the coupling component C being selected from the group consisting of phenols coupling in o-position and unsubstituted or substituted by low molecular weight alkyl or alkoxy, dialkylamino or acylamino which is C.sub.1 -C.sub.4 -alkanoylamino, C.sub.1 -C.sub.4 -alkylsulfonylamino, C.sub.1 -C.sub.4 -alkoxycarbonylamino, aroylamino or arylsulfonylamino;
• naphthols which are unsubstituted or substituted by C.sub.1 -C.sub.4 -alkyl or alkoxy, chlorine, amino, sulfo or acylamino which is as defined above;
• 5-pyrazolones or 5-aminopyrazoles each of which has in the 1-position phenyl or naphthyl which is unsubstituted or substituted by chlorine, nitro, C.sub.1 -C.sub.4 -alkyl or alkoxy groups or sulfo groups and which have in the 3-position a C.sub.1 -C.sub.4 -alkyl or carboxyl group;
• naphthylamines which are unsubstituted or substituted by sulfo, sulfonamido or sulfone groups;
• acetoacetamides which, if they contain an anilide nucelus, are unsubstituted in said nucleus or substituted by chlorine, bromine, nitro or C.sub.1 -C.sub.4 -alkyl, alkoxy or sulfo groups;
• 6-hydroxy-3-cyano- or 6-hydroxy-3-carboxamido-4-alkyl-2-pyridones which are substituted in the 1-position by unsubstituted C.sub.1 -C.sub.4 -alkyl, .beta.-hydroxyethyl, .beta.-aminoethyl or .gamma.-isopropoxypropyl, or by phenyl, and are unsubstituted in the 4-position or are substituted there by a C.sub.1 -C.sub.4 -alkyl group, or hydroxyquinoles,
• X is oxygen or a group of the formula --NR-- in which R is hydrogen or a C.sub.1 -C.sub.4 -alkyl group,
• Ar.sub.1 and Ar.sub.2 are the same or different and are independently of each other unsubstituted benzene or naphthalene or benzene which is substituted by chlorine, bromine, nitro, sulfo, sulfamoyl, N-monoalkylated or N,N-dialkylated sulfamoyl, alkylsulfonyl, alkyl or alkoxy, or naphthyl which is substituted by sulfo, or thiazolyl, benzothiazolyl, imidazolyl, quinolinyl, oxazolyl or benzoxazolyl,
