Zusammenfassung:	1. Cobalt complexes of the general formula see diagramm : EP0019128,P13,F1 wherein the sulphonic acid group is on one of the benzene rings or on an aryl nucleus of the arylazo or arylsulphonyl groups in R6 or R7 , M**+ denotes a colourless cation, for example an alkali metal ion, such as a lithium ion, sodium ion or potassium ion, or ammonium, or an ammonium substituted by C1 -C4 -alkyl groups or hydroxy-C1 -C4 -alkyl groups, R1 denotes hydrogen, chlorine, C1 -C4 -alkyl, acylamino or nitro, R2 , R3 and R5 independently of one another denote hydrogen, halogen, C1 -C4 -alkyl, C1 -C4 -alkoxy, and R6 and R7 independently of one another denote hydrogen, nitro, halogen, C1 -C4 -alkyl, C1 -C4 -alkoxy, acylamino, arylazo, C1 -C4 -alkylsulphonyl or arylsulphonyl.
